PLANT FOR USE OF METHANE-CONTAINING GAS OF COAL DEPOSITS FOR PRODUCTION OF THERMAL AND ELECTRIC ENERGY

摘要

A plant for use of methane-containing gas of coal deposits for production of thermal and electric energy has device for collection and enrichment of methane-containing gas, device for purification of collected saturated methane-containing gas for following use, appliance for conversion of chemical energy of methane-containing gas to other forms of energy, gas conduits that connect devices for collection and enrichment of gas, its saturation and conversion of its energy. It includes cogeneration plants on basis of gas-piston engines with electric generators and boiler-utilizers for combined production of thermal and electric power, device for priority takeoff of methane-containing gas of degassing of coal beds developed from wells drilled from underground workings with respect to methane concentration, its distribution between block for preparation of fuel gas and collector of depleted gas, block for preparation of fuel gas for saturation of taken out gas with largest concentration of methane (fuel gas) with gas of technological wells of natural gas from gas mains and preparation for following use, collector of depleted gas with plug, cyclone for gas from technogenous wells purification with tank-degasser for discharge of drop moisture connected with tank for preparation of fuel gas, gas conduit with throttle for supply of natural gas from gas mains to block of saturation of fuel gas, system of technological gas conduits, system of automation and control of the appliance.
