Description

technical field [0001] The invention belongs to the technical field of waste heat energy recovery in coalfield fire areas, and specifically refers to the realization of thermal energy power generation in coalfield fire areas by utilizing heat pipe heat conduction technology and the principle of thermoelectric power generation. Background technique [0002] Coal fire refers to a large-area coalfield fire that is caused by coal burning due to oxidation and heat accumulation under natural environment or human factors and continues to develop. Coal fires are common in countries and regions such as India, the United States, Russia, Australia, Indonesia, and Central Asia, but coal fires are particularly serious in China. Spontaneous combustion of coal in coalfield fire areas not only has a huge impact on the economy, society and ecological environment, but also poses a great threat to human health and animal survival. At present, coal fire treatment generally adopts a comprehensi...
