The process of gasification is one of the promising technologies of clean combustible gas production from low-grade coals, such as lignite, coal mud and subbituminous LR coals, and from biomass and waste. However, depending on the type of gasification material, the following aspects require investigation and development: the selection of a gasification technology (including parameters and gasifying...
The paper presents an attempt to evaluate the impact of coal and coal mine methane cocombustion on the physics of the heat exchange in an 140 t/h pulverized-coal boiler through an analysis of 21 combinations of the boiler operating parameters – three different boiler loads (50, 75, and 100%) and seven values of the fired gas thermal contribution (0–60%). The obtained results are the temperature distribution...
