摘要
为了预防煤矸石山堆积带来的自燃发火问题,并充分利用煤矸石氧化产生的热量,有必要估算煤矸石山内部的热量,设计热能提取与利用方案,分析热棒-热泵联合取热的经济效益及环境效益。煤矸石山内可以埋设热棒转移出煤矸石氧化热能,然后通过热泵提取热能进行利用。结果表明,利用热棒进行取热,对煤矸石山自燃问题的治理非常有效,而且将提取的热能用于居民供暖与热水供应,能够获得良好的综合效益。
In order to prevent the problem of spontaneous combustion caused by the accumulation of coal gangue,and to fully utilize the heat generated by the oxidation of coal gangue,it is necessary to estimate the heat inside the coal gangue,design a thermal energy extraction and utilization plan,and analyze the economic and environmental benefits of heat rodheat pump combined heat extraction.A thermal rod can be buried in the coal gangue hill to transfer the oxidation heat energy of the coal gangue,and then the heat energy is extracted through a heat pump for utilization.The results show that using heat rods for heat extraction is very effective in treating the problem of spontaneous combustion in coal gangue hills,and using the extracted heat energy for residential heating and hot water supply can achieve good comprehensive benefits.
