The use of binary mixtures in TPP steam generators as fuels is caused by various reasons, such as improvement of ignition conditions and the possible environmental benefits of burning binary mixtures. Since the existing boilers of TPP were calculated for ... see more

Theoretically, the combustion stability of solid fuel, which during the combustion process is decomposed according to the “solid phase – liquid phase – gas” scheme, is investigated. The physical and mathematical models for th... see more

The object of research is the combined 2-component solid fuel «coal-municipal solid waste» (MSW) in 5 parts with concentrations of 0–100 (wt. %) of each component. One of the most problematic places is the improvement of solid waste gasification processes... see more
