煤矿瓦斯发电技术综述

Research on Generation Technology of Coal Mine Gas

煤矿瓦斯是煤层伴生物,主要成分是甲烷,储量丰富,与天然气储量相当。开发利用煤矿瓦斯具有安全、节能、环保、增效等重要意义。介绍了3种煤矿瓦斯开发方式及其产气特点,阐述了国内外瓦斯发电现状,并对燃气轮机和燃气内燃机应用条件进行了比较,提出了煤矿瓦斯发电需要解决的"技术安全、瓦斯浓度的适应性和压力的变化"三大技术问题,重点论述了利用燃气发动机进行瓦斯发电的三大类、十项专有的关键技术,并就瓦斯发电市场前景进行了展望。

The coal mine gas is the accompaniment of coal seam, whose main component is methane and whose reserve is equivalent to the reserve of natural gas. The development of coal mine gas is important to safety, energy saving, environment protection and increasing efficiency. The developing methods and gas production characteristic of three coal mine gas were first introduced, the status of gas power generation was then described, the application conditions of gas turbine and internal combustion engine were further compared, the three key problems like technology safety, gas concentration adaptability and pressure variation were subsequently put forward, and finally ten items key technologies, which were divided into three main types, of gas power generation were mainly discussed and the market prospect of gas power generation was simultaneously forecast.
