Abstract

When developing coal seams with high gas content, attempts are often made to use coal mine methane, which is co-extracted by the degasification system, for internal energy needs by burning it in gas piston units. In addition, a progressive approach in this area is the co-use of the heat of the exhaust gases. By combining these two approaches – methane utilization and exhaust gas heat recovery – it is possible to create a synergistic effect in the mining industry. The study economically substantiates the hypothesis of using waste heat boilers for heat supply to industrial and individual consumers. According to the calculation results, the use of KU-80-3M will pay for the project in less than 2 years. The application of the proposed project for the recovery of high-potential heat of exhaust gases during coal mine methane combustion in surface gas piston units, namely the use of a waste heat boiler with a higher water vapor productivity will increase the production of water vapor; reduce the energy intensity index of cogeneration; increase the operational efficiency of mining production and reduce the emission of coal mine methane into the atmosphere in a less energy-intensive manner.

Keywords

Utilization of coal mine methane, gas piston units, energy efficiency, waste heat boiler, coal seam, heat, cogeneration systems.
