Solid fuel plays significant role in the development of civilization as the main fuel source. Use of low-grade (ash content ∼ 40-45%) coal is partially offset environmental problems also affect human health when it is burned. As the main industrial corporations use coal, in particular low-grade high-ash content coal from Ekibastuz coal basin because of its cheap cost the atmosphere of megacities like Almaty is polluted by noxious volatile. In this study were developed a mathematical model of turbulent heat and mass transfer process occurring in the combustion chamber of SB-39 of Aksusskaya TPP for control the concentration of volatile and to recommend the optimize methods for burning process. Based on 3D computer modeling investigated formation of harmful dust and gas emissions during the combustion of low-grade coal and offered cost-effective methods of burning.
