A combined cooling heating and power technology applied in low-concentration mine gas oxidization utilization

为了提高我国低浓度抽采瓦斯和乏风瓦斯的利用率,提出一种将低浓度瓦斯氧化并利用余热进行冷热电联供方法。该方法利用热逆流氧化技术实现对低浓度瓦斯高效氧化,抽取部分高温烟气生产高品位的蒸汽推动汽轮机发电,同时可从汽轮机抽取低压蒸汽,一部分用于供暖,一部分用于溴化锂吸收式制冷机制冷。分析表明,该方法实现了对低浓度瓦斯的有效氧化,减少了温室气体排放,并对余热实现了梯级利用,大大提高了系统的热能利用率,具有良好的推广应用价值。

To improve the utilization ratio of low-concentration mine gas and ventilation air methane（ VAM） ,a combined cooling heating and power technology（CCHP） applied in low-concentration mine gas oxidization utilization was present in this paper.The method can oxidate mine gas efficiently by using thermal reverse-flow reactor,and extract part of high temperature gas to produce steam,drive tur-bine,and refrigerate.This technology can oxidize low-concentration gas efficiently,and achieves energy cascade utilization.The technolo-gy is worthy of popularization and application.
