AB  - Coal-fired power plant technologies should provide higher efficiency of energy conversion, reduction of pollutants emission, operation of facilities in a wide range of loads and efficient utilization of variable quality fuels. In order to achieve these tasks, mathematical modeling is regularly used worldwide for optimization of boiler operation. Reduction of pollutants emission is the task of greatest concerns. Among the most important pollutants are oxides of nitrogen and sulfur. Combustion process modifications for NOx control and sorbent injection for SO2 control are cost-effective clean coal technologies, used either standalone or with other methods. An in-house developed computer code was applied for simulation of processes in the 350 MWe boiler furnace, tangentially fired by pulverized lignite. Predictions suggested optimal combustion organization providing the NOx emission reduction of up to 20 -30%, with the flame position improvement. Boiler thermal calculations showed that the facility was to be controlled within narrow limits of working parameters. SO2 reduction by injection of Ca-based sorbent particles into the furnace was simulated for different operation parameters. Such a complex approach enables effective evaluation of alternative solutions, considering emissions, flame position and efficiency of furnace processes and the boiler unit. (C) 2013 Elsevier Ltd.

AB  - The European normatives prescribe content of 200 mg/Nm(3) NO for pulverized coal combusting power plants. In order to reduce content of NOx in Serbian thermal power plant (TPP) square Kostolac B square its necessary to implement particular measures until 2016. The mathematical model of lignite combustion in the steam boiler furnace is defined and applied to analyze the possibility of implementing certain primary measures for reducing nitrogen oxides and their effects on the steam boiler operation. This model includes processes in the coal-fired furnace and defines radiating reactive two-phase turbulent flow. The model of turbulent flow also contains sub-model of fuel and thermal NOx formation and destruction. This complex mathematical model is related to thermal and aerodynamic calculations of the steam boiler within a unified calculation system in order to analyze the steam boiler overall work. This system provides calculations with a number of influential parameters. The steam boiler calculations for unit 1 (350 MWe) of TPP square Kostolac B square are implemented for existing and modified combustion system in order to achieve effective, reliable and ecological facility work. The paper presents the influence analysis of large number of parameters on the steam boiler operation with an accepted concept of primary measures. Presented system of calculations is verified against measurements in TPP square Kostolac B square. (C) 2015 Elsevier Ltd. All rights reserved.

AB  - The objective of the research was to find if an agreement of the results of a numerical investigation with experimental data could be achieved considering the two-phase medium in thermal equilibrium. Influence of the gray radiative properties on the radiative heat exchange inside pulverized lignite fired furnaces was investigated using the computational fluid dynamics (CFD) code based on a comprehensive mathematical model of the process. Radiative heat exchange was calculated using Hottels zonal model. Heat transfer rates and wall fluxes increased for small values of the total extinction coefficient, K-t LT 0.2 m(-1); decreased for large values of K-t, K-t GT 2.0 m(-1); and were maximal for moderate values of K-t, 0.2 LT K-t LT 2.0 m(-1). Heat transfer rates and wall fluxes decreased with the increase of the scattering albedo, though the decrease was considerable only for omega GT 0.5. Agreement with the experimental data was obtained for the moderate values of the K-t and for scattering albedo 0.1 LT omega LT 0.5. (C) 2014 Elsevier Masson SAS. All rights reserved.

AB  - Comparison of the numerical investigation results was carried out when the simple gray gas (SGG) and weighted sum of gray gases (WSGG) models are used to model the radiative properties of the gas phase inside the lignite fired furnaces. Comprehensive mathematical model of the tangentially fired furnace by pulverized lignite was made. Gas radiative properties were modeled by the SGG and WSGG models. Radiative heat transfer was modeled by the zonal model. Gas-phase variables and absorbed wall fluxes were compared on the basis of the relative differences that were determined for all control volumes and surface zones. Average relative differences of the gas-phase temperatures were about 1.0%. Average relative differences of the absorbed wall fluxes were from 2.0% to 5.0%. Absorbed wall fluxes determined by the SGG model were bigger than those determined by the WSGG model. Differences of the heat transfer rates of the absorbed radiation through the furnace walls were expressed in percents of heat transfer rates determined by the SGG model and were similar to the average relative differences of absorbed wall fluxes. Results justify application of the SGG model in comprehensive mathematical models of lignite-fired furnaces. (C) 2012 Elsevier Ltd. All rights reserved.

Aiming to increase the MVC Kikinda energy plant capacity, one gas turbine of 14 MW or 17 MW is going to be installed. In regard to relatively high gas temperature and a large amount of the unused oxygen from the air in the exhaust gas, it is specified to split exhaust gas into the two equal streams and import them into the two existing steam boilers, each having production of 16.67 kg/s (60 t/h). In order to use the exhaust gas heat, as well as oxygen contained within, it is necessary to replace the existing burners and to reconstruct the heat exchangers in the steam boiler vertical convective pass.

AB  - Considerable research efforts focus on modeling NOx formation/destruction and predicting NOx emission so that it can be controlled. A motivation for this numerical study was to examine the efficiency of combustion modifications in the furnaces of Kostolac B 350 MWe boiler units, tangentially fired by pulverized lignite. Numerical analysis was done by an in-house developed NOx submodel, coupled with differential comprehensive combustion model, previously developed and validated. The NOx submodel focuses on homogeneous reactions of both the fuel and the thermal NO formation/destruction processes. The submodel was validated by comparison of predicted NOx emissions with available measurements at the boiler units. Selected predictions of the emission, the furnace exit gas temperature, NO concentration, gas temperature, and velocity field are given for the case-study furnace under different operating conditions. The individual or combined effects of coal and preheated air distribution over the individual burners and the burner tiers, the grinding fineness and quality of coal, and the cold air ingress were investigated. Reduced emissions of up to 20-30% can be achieved only by proper organization of the combustion process. Obtained results were verified by the boiler thermal calculations. An optimal range of the furnace exit gas temperatures was proposed, with respect to the safe operation of the steam superheater. Simulations by means of a computer code developed for the purpose, showed that the air staging using overfire air ports might provide the NOx emission reduction of up to 24% in the test-cases with relatively high emission and up to 7% of additional reduction in already optimized cases.

AB  - A possibility of simplification of the scattering phase function of a pulverized coal flame was analyzed in the paper. It was showed that the type of radiation scattering of a pulverized coal flame is between two limiting cases: isotropic and forward scattering. A comprehensive mathematical model of a tangentially fired furnace by pulverized coal was formed. Radiative heat transfer was modeled using the six-flux model. Grid independent results of the numerical simulations were obtained. The mathematical model was verified by comparison of the results of numerical simulations with results of measurements. The influence of the type of radiation scattering on results of numerical simulation was analyzed through the relative and average differences of the gas-phase temperatures, the total radiation fluxes, and the absorbed wall fluxes of the left furnace wall. The investigation showed that the total radiation fluxes were considerably influenced by the type of radiation scattering. On the other hand, the gas-phase temperatures and the absorbed wall fluxes were much less influenced by the type of radiation scattering. The results justify the use of the scattering phase function corresponding to isotropic scattering in radiation models of comprehensive mathematical models of pulverized coal fired furnaces.

It was showed that the type of radiation scattering of a pulverized coal flame is between two limiting cases: isotropic and forward scattering. A comprehensive mathematical model of a tangentially fired furnace by pulverized coal was formed. Radiative heat transfer was modeled using the six-flux model. Grid independent results of the numerical simulations were obtained. The mathematical model was verified by comparison of the results of numerical simulations with results of measurements. The influence of the type of radiation scattering on results of numerical simulation was analyzed through the relative and average differences of the gas-phase temperatures, the total radiation fluxes, and the absorbed wall fluxes of the left furnace wall. The investigation showed that the total radiation fluxes were considerably influenced by the type of radiation scattering. On the other hand, the gas-phase temperatures and the absorbed wall fluxes were much less influenced by the type of radiation scattering. The results justify the use of the scattering phase function corresponding to isotropic scattering in radiation models of comprehensive mathematical models of pulverized coal fired furnaces.

AB  - One of the main tasks during the design or simulation and analyses of the utility steam boiler operation is the prediction of a distribution of mill gases and hot air flow rates between burners sections. These are the boundary conditions for the combustion process in the boiler furnace, and they strongly influence the steam boiler economy and reliability of operation. A computer code for the prediction of mill gases and hot air distribution between boiler burners has been developed. The code is based on simultaneous calculations of material and heat balances for the fail mill and corresponding air tracts. This paper presents a methodology of performed calculations, the code structure, and results obtained for the steam boiler furnace of 350 MWe thermal power plant equipped with eight fall mills.
