Here we present the results of 3D computer modeling of combustion coal-dust in the combustion chamber of
the boiler BKZ-75. Calculations performed by the numerical model for the conditions adopted by the
organization of the actual process on Shahtynskaya Thermal Power Plant. Carried out in this paper, the
research allowed identifying the main patterns of distribution of heat exchange performance in the entire
volume of the combustion chamber of the researched boiler and at the exit from it. The authors carried out
numerical experiments of 3D computer modeling for describing complex processes of heat and mass transfer.
Proposed the numerical methods of solving a system of equations describing heat and mass transfer, and a
program package has been developed for solving combustion problems. New computer modeling results of
turbulent heat-and mass transfer process received during burning coal-dust fuel in the combustion chamber of
the BKZ-75 boiler. The developed technologies will make it possible to exclude inefficient and costly methods
of conducting research in the field of fuel-burning energy industry. Numerical modeling including
thermodynamic, kinetic and three-dimensional computer modeling of burning low-grade Kazakhstan coal will
optimize the process of ignition, combustion and stabilization of coal combustion, and also develop technical
solutions for the modernization of existing power plants and for the design of new power boilers.
