Abstract

Language:

The aim of this paper is to study the combustion processes of organizing non-standard fuel burning using a numerical approach in a boiler unit BKZ –210–140 with steam capacity of 210 t/h. The Euler-Lagrange aerothermochemical technique of describing physical and chemical processes in the furnace volume by the FIRE 3D application package was utilized. Special attention is paid to the numerical modeling results, which conclude on aerodynamics processes, heat exchange, and combustion in the furnace volume. The research object is the vertical water-tube boiler unit E-210-140, equipped with four straight-flow burners for burning Chihezsky and Pavlovsky brown coal. The results of mathematical modeling demonstrate the feasibility of burning Pavlovsky brown coal in the researched boiler furnace, as the resulting furnace exit gas temperature aligns closely with normative calculation methods, indicating the adequacy of the models used. Additionally, the distribution patterns of particles in the furnace volume substantiate their aerodynamic behavior, and the temperature distribution suggests that screen surfaces operate under lesser load, reducing the likelihood of slagging when combusting Pavlovsky brown coal.
