The Study On The Use Of Coal Mine Gas Based On CCHP Technologies

China is a coal-bed methane and coal seam gas reserves, abundant countries, the annual emissions from coal mine gas up to 130 billion m3, for the safety in production terms, a long time, using the amount of less than 1 billion m3, the majority were in vain discharged into the atmosphere, causing a huge waste of energy, but also increased the pressure on greenhouse gas emissions.Increasingly scarce in the energy tension of today, the use of thermoelectric cooling and power production technologies, cascade development and utilization of coal mine gas-rich energy resources, for ease pressure on domestic energy, reduce China's dependence on international energy markets, for our country, is necessary.This paper mainly coal gas as an object of study, based on Wang Fu Mining Group Company Camp mine mouth coal-bed methane power plant project as a baseline research platform, the application CCHP technical principle, the right bed methane gas source parameter determination of the conditions, throughout the whole mine heat load, cooling load, load distribution scheme for a reasonable analysis and calculation, as a basis for the completion of a thermoelectric cooling system, generator sets, heating units and cooling units selection analysis and matching; Application of first law of thermodynamics and the second law of thermodynamics, the CCHP systems and program analysis of thermal economy, based on the financial evaluation and economic evaluation method of the system of technical and economic analysis, and obtain the corresponding conclusion for the conditional mine, follow-up launched a large-scale CCHP systems, promoting energy-saving emission reduction, increase enterprise efficiency, this paper can be a very good reference value.
