浅谈煤层气发电技术及应用前景

Discussion on coalbed methane(CBM) power generation technology and application prospect

目前,全球能源危机日益严重,环境污染带来的社会影响也与日俱增,成为全球经济发展的痛点,引发全世界关注。煤层气,又称煤矿瓦斯,是与煤伴生的一种清洁、高效的气体资源。煤层气发电是煤层气资源高效利用的最佳方式之一,因其燃烧热值高、燃烧后对环境污染小,现阶段受到越来越多的重视。介绍了我国煤层气的资源量及应用情况,详细阐述了煤层气发电的关键技术;在国家政策指引的背景下,对煤层气发电技术的应用前景进行展望。结果表明,煤层气发电技术能充分利用煤层气能源,大大提高煤层气燃烧效率,打破了人们对煤层气利用效率低下的传统观念。

At present, the global energy crisis is growing, and the social impact of environmental pollution is becoming more and more serious. Now, the worldwide is concerning the pain spot of environmental pollution. Coalbed methane, which is also called coal mine gas, is a kind of clear and efficient gas resources associated with coal. CBM power generation is one of the best ways for the efficient utiliza- tion of CBM resources. At the present stage, more and more attention is being paid on CBM power generation, because of its high calorif- ic value and lower pollution to the environment. First of all, this paper introduced the resources and applications of the CBM in China; secondly, this paper described the key technologies of CBM power generation;finally, under the guidance of national policy, the applica- tion prospect of CBM power generation technology was prospected. The results show that, coalbed methane power generation technology can makes full uses of coalbed methane energy, improve combustion efficiency of coalbed methane, and has broken the traditional con- cept about inefficiency utilization of coalbed methane.
