  3. This work investigates heat transfer characteristics in a bubbling fluidized bed with a submerged superheater tube bundles under conditions of an integrated fluidized bed heat exchanger (Integrated Recycle Heat Exchanger, Intrextm) of a large-scale circulating fluidized bed boiler. The effect of mean bed particle size, normalized suspension density, and fluidizing number on the average heat transfer coefficient between the immersed horizontal tubes and the bed was evaluated. The physical parameters of bed particles and fluidizing air in the external heat exchanger were measured at different CFB unit loads. Bubble fraction and contacting time of emulsion phase on the heat transfer surface were calculated on the basis of operating data of fluidized bed heat exchanger. A mechanistic heat transfer model was used to predict the heat transfer coefficient. Depending on emulsion density and the local dynamics of gas and bed particles, the average heat transfer coefficient (havg) varied in a range of 255-381 W/(m2K), showing an increasing trend with the decrease in bed particle size. Moreover, havg decreased with increasing emulsion contact time on the tube surface with the reduction of the solids mixing. Obtained results were compared with literature data.

    [Streszczenie]
  5. The effect of pressure drop on bed-to-wall heat transfer at membrane walls in a 966 MWth circulating fluidized bed (CFB) furnace was studied. By using the hydrodynamic parameters and the mechanistic heat transfer model based on cluster renewal approach, bed-to-wall heat transfer coefficient was estimated. Furthermore, the heat transfer conditions in the CFB furnace were analyzed by taking into account concurrently percentage contributions of particle convection, gas convection, cluster convection, gas conduction and also radiation from dispersed phase and clusters. The heat transfer mechanisms in a CFB furnace have been analyzed for dilute phase and dense phase conditions above the secondary air injection, where membrane wall surfaces are located. The increased operating pressure drop enhances the particle convection component due to increase of cluster thermal conductivity was well as with decrease of boundary layer thickness. The local bed-to-wall heat transfer coefficient increases with operating furnace pressure, because of increased bed particle concentration. Also, the experimental results showed that the variation in share of convective mode and radiative mode was depended on local suspension density. The reported results from the cluster renewal approach were compared with the open CFB literature.

    [Streszczenie]
  7. The effect of bed particle size on the local heat transfer coefficient between a fluidized bed and vertical rifled tubes (38mm-O.D.) has been determined in a large-scale circulating fluidized bed (CFB) reactor. Bed particles with different Sauter mean particle diameter within the range of 0.219-0.411mm and particle density in the range of 2650-2750 kg/m3 were used as bed material in this heat transfer study. A gas fluidized bed furnace with 27.6x10.6m cross-section above refractory line and 48m in height was used. Air coal firing conditions at the membrane wall in the form of water tubes welded with lateral fins corresponded to a suspension density covering the range of 1.36-6.22kg/m3, furnace temperatures in the range of 1080-1164K, a superficial gas velocity varied from 2.99 to 5.11m/s and solids circulation flux covered a range of 23.3-26.2kg/(m2s). For these operating conditions, the heat transfer analysis of CFB reactor with detailed analysis of bed-to-wall heat transfer coefficient along furnace height was investigated. In this work, the overall heat transfer coefficient was estimated using a mechanistic heat transfer model based on cluster renewal approach. The experimental results show that: (i) higher heat transfer coefficients along furnace height were found under finer bed particles size dp<0.241mm, (ii) heat transfer data confirms strong dependency of the overall heat transfer coefficient on suspension density and also hydrodynamic conditions within CFB furnace, (iii) for small bed particles, dp<0.233mm, the particle convection component plays dominant role in heat transfer mechanism, (iv) for large bed particles, dp>0.366mm, the effect of particle size on contribution of radiation from dispersed phase become essential with particle diameter increasing, and (v) for all bed particles with diameters in the range of 0.240-0.411mm, the gas convection heat transfer coefficient between the fluidized bed (Geldart B particles) and the rifled tubes increased as the bed particles size increased.

  9. The interrelation between fuzzy logic and cluster renewal approaches for heat transfer modeling in a circulating fluidized bed (CFB) has been established based on a local furnace data. The furnace data have been measured in a 1296 t/h CFB boiler with low level of flue gas recirculation. In the present study, the bed temperature and suspension density were treated as experimental variables along the furnace height. The measured bed temperature and suspension density were varied in the range of 1131–1156 K and 1.93–6.32 kg/m3, respectively. Using the heat transfer coefficient for commercial CFB combustor, two empirical heat transfer correlation were developed in terms of important operating parameters including bed temperature and also suspension density. The fuzzy logic results were found to be in good agreement with the corresponding experimental heat transfer data obtained based on cluster renewal approach. The predicted bed-to-wall heat transfer coefficient covered a range of 109–241 W/(m2K) and 111–240 W/(m2K), for fuzzy logic and cluster renewal approach respectively. The divergence in calculated heat flux recovery along the furnace height between fuzzy logic and cluster renewal approach did not exceeded ±2%.

  11. This work shows heat transfer characteristics in a bubbling fluidized bed (BFB) with a
    submerged tube bundles. The effect of mean bed particle size (dp) and fluidizing number on
    the average heat transfer coefficient (havg) between immersed horizontal tube bundles and a
    BFB has been determined in an external heat exchanger (EHE). Operating conditions at
    horizontal tube bundles in an EHE corresponded to dp in the range of 0.219-0.444mm, gas
    velocity covering the range of 0.14-0.25m/s, minimum fluidization velocity varied from
    0.0228 to 0.0979m/s, bed temperature in the range of 929-1083K, metal temperature covered
    a range of 646-698K and suspension density of 768-982kg/m^3. A packet-renewal model was
    used to predict the havg. At a given emulsion density, the local dynamics of gas and bed
    particles, the havg varied in the range of 255-381W/(m^2K) and showed an increasing trend
    with the decrease in dp. Moreover, havg decreased with increasing emulsion contact time on
    the tube surface due to the reduced solids mixing (i.e. the replacement rate of bed particles by
    bubbles). The findings showed that large distorted bubbles and solids sliding at tube surface
    led to an increase in the bed-to-tube heat transfer coefficient.

  14. In the present work, the heat transfer study focuses on assessment of the impact of bed temperature on the local heat transfer characteristic between a fluidized bed and vertical rifled tubes (38mm-O.D.) in a commercial circulating fluidized bed (CFB) boiler. Heat transfer behavior in a 1296t/h supercritical CFB furnace has been analyzed for Geldart B particle with Sauter mean diameter of 0.219 and 0.246mm. The heat transfer experiments were conducted for the active heat transfer surface in the form of membrane tube with a longitudinal fin at the tube crest under the normal operating conditions of CFB boiler. A heat transfer analysis of CFB boiler with detailed consideration of the bed-to-wall heat transfer coefficient and the contribution of heat transfer mechanisms inside furnace chamber were investigated using mechanistic heat transfer model based on cluster renewal approach. The predicted values of heat transfer coefficient are compared with empirical correlation for CFB units in large-scale.

  16. The Fuzzy Logic (FL) approach is proposed in this paper to determine the overall heat transfer coefficient in thecombustion chamber of a large-scale 670 t/h circulating fluidized bed (CFB) boiler. The FL model for the prediction of bed-to-wall heat transfer coefficient was successfully validated against data from the boiler.

  24. This paper focuses on assessment of the effect of flue gas recirculation (FGR) on heat transfer behavior in a 1296t/h supercritical coal-fired CFB combustor. The performance test in supercritical CFB combustor with capacity 966MWth was performed with low level of flue gas recirculation rate 6.9% into furnace chamber, for 80% unit load at the bed pressure of 7.7kPa and the ratio of secondary air to the primary air SA/PA=0.33.Heat transfer behavior in a supercritical CFB furnace between the active heat transfer surfaces (membrane wall and superheater) and bed material has been analyzed for Geldart B particle with Sauter mean diameters of 0.219 and 0.246mm. Bed material used in the heat transfer experiments had particle density of 2700kg/m3. A mechanistic heat transfer model based on cluster renewal approach was used in this work. A heat transfer analysis of CFB combustion system with detailed consideration of bed-to-wall heat transfer coefficient distributions along furnace height is investigated. Heat transfer data for FGR test were compared with the data obtained for representative conditions without recycled flue gases back to the furnace through star-up burners.

  28. The purpose of this work is to find a correlation for heat transfer to walls in a 1296 t/h supercritical circulating fluidized bed (CFB) boiler. The effect of bed-to-wall heat transfer coefficient in a long active heat transfer surface was discussed, excluding the radiation component. Experiments for four different unit loads (i.e. 100% MCR, 80% MCR, 60% MCR and 40% MCR) were conductedat a constant excess air ratio and high level of bed pressure (ca. 6 kPa) in each test run. The empirical correlation of the heat transfer coefficient in a large-scale CFB boiler was mainly determined by two key operating parameters, the suspension density and the bed temperature. Furthermore, the data processing was used in order to develop the empirical correlation ranges between 3.05 to 5.35 m·s-1 for the gas superficial velocity, 0.25 to 0.51 for the ratio of the secondary to the primary air, 1028 to 1137K for bed temperature inside the furnace chamber of a commercial CFB boiler,and1.20 to 553 kg·m-3 for suspension density. The suspension density was specified on the base of pressure measurements inside the boiler’s combustion chamber using pressure sensors. Pressure measurements were collected at the measuring ports situated on the front wall of the combustion chamber. The obtained correlation of the heat transfer coefficient is in agreement with the data obtained from typical industrial CFB boilers.

  30. The role of bed particle size in the heat transfer to membrane walls of a supercritical circulating fluidized bed (CFB) combustion system was studied. In this work, values of the heat transfer coefficient between the membrane walls and the bed include contributions of particle convection, gas convection, cluster convection, gas conduction and also radiation. The heat transfer conditions in the CFB combustor were analyzed for five sizes of bed inventory, with Sauter mean particle diameters of 0.219, 0.232, 0.246, 0.365 and 0.411 mm (Geldart group B). The operating parameters of a circulating fluidized bed combustor covered a range of 3.13–5.11 m s−1 for superficial gas velocity, 22.3–26.2 kg m−2 s−1 for the circulation rate of solids, 0.11–0.33 for the secondary to primary air ratio and 7.16–8.44 kPa pressure drop. Furthermore, the bed temperature, suspension density and the main parameters of cluster renewal approach were treated as experimental variables along the furnace height. To estimate the local bed to wall heat transfer coefficient, some experimental data from CFB boiler and some simple correlations were used. A simple semi-empirical method was proposed to estimate the overall heat transfer coefficient inside the furnace as a function of particle size and suspension density with an accuracy of 21%. Computationally obtained results were compared with the experimental data for CFB unit in a large-scale. It was observed that both bed particle sizes as well as the suspension density significantly influence heat transfer conditions.

  32. Experimental research has been carried out in a supercritical circulating fluidized bed combustor in order to indicate the effect of the bed particle size on bed-to-wall heat transfer coefficient. Bed inventory used were 0.219, 0.246 and 0.411mm Sauter mean particles diameter. The operating parameters of a circulating fluidized bed combustor covered a range from 3.13 to 5.11 m/s for superficial gas velocity, 23.7 to 26.2 kg/(m2s) for the circulation rate of solids, 0.33 for the secondary air fraction and 7500 to 8440 Pa pressure drop. Furthermore, the bed temperature, suspension density and the main parameters of cluster renewal approach were treated as experimental variables along the furnace height. The cluster renewal approach was used in order to predict bed-to wall heat transfer coefficient. A simple semi-empirical method was proposed to estimate the overall heat transfer coefficient inside the furnace as a function of particle size and suspension density. The computationally obtained results were compared with the experimental data of this work.

  34. In the present work the effect of flue gas recirculation on bed-to-wall heat transfer in a large-scale CFB combustor is investigated. A mechanistic model based on a cluster renewal approach is used in this investigation. The heat transfer mechanism in a CFB combustor has been analysed for a dilute phase and a dense phase conditions above the secondary air injection, where membrane wall surfaces and radiant superheaters are located. Experimental heat transfer studies were conducted on a 1296 [t·h-1] supercritical CFB combustor at the high bed pressure (ca. 7.7 [kPa]), the ratio of secondary air to primary air SA/PA=0.33 and also under flue gas recirculation rate 6.9% using the bed material of mean size in the range of 219 to 246 [mm] (group B). The fluidizing gas velocity and the solid circulation flux varied in the range of 3.89-4.27 [m·s-1] and 23.7-25.6 [kg·(m-2·s-1)], respectively. Furthermore, the bed temperature and the suspension density were regarded as experimental variables along furnace height. The percentage contributions of convection and radiation heat transfer components were estimated. The variation in contributions was depended on the operating conditions i.e. both solid suspension density and bed temperature. During all tests, the average contribution of convection and radiation heat transfer components varied between 29%-45% and 55%-71%, respectively. The results confirmed an increasing trend of the heat transfer coefficient (110-241 [W· (m-2·K-1)] with an increase in average suspension density (1.93-1200 [kg·m-3]).

  36. The purpose of this work was to determine the impact of a operating conditions on the deNOx system effciency in a 966 MWth supercritical circulating fluidized bed boiler. Experimental tests were carried out on a full-scale DeNOx system installed in the world’s largest once through supercritical circulating fluidized bed boiler. In this work, the e ects of the following parameters were studied: flue gas temperature inside the separators between 636oC and 845oC, relative  ammonia mass flow over the range 0.22–1.00 and three relative values of O2 concentration (i.e. 0.94, 1.0 and 1.13). The eciency of deNOx system increases (ca. 53%) with increasing relative ammonia mass flow. A maximum DeNOx system eciency (ca. 70%) was achieved at flue gas temperature in the range from 720oC to 790oC. In the case of all unit loads, deNOx system effciency from 36% to 70% was observed and performs a standard emissions relate to permissible concentration of NOx in the flue gas.

  69. In this paper the results of experimental studies of particle velocity fields in a free stream are presented. Measurements of particle velocity were carried out by means of a novel laser sheet technique, in which the laser beam was modulated with the help of an electronic modulator. Thanks to that, it was possible to register multiexposure pictures, called specklegrams, which record single particle trajectories in selected areas of the flow. On the basis of this, three components of particle velocity vector can be estimated. The novel algorithm for quantitative analysis of specklegrams was proposed. It consists in using the scanline, which is the searching of the particle trajectories by their rotating and the application of the correlation technique for the determined periodic brightness distribution function
