Coal mine gas power generation can effectively solve coal mine gas accidents, improve coal mine safety production conditions, increase clean energy supply, reduce greenhouse gas emissions, and achieve multiple goals of protecting life, resources, and environment.

对于瓦斯发电机组，燃气燃料的能量只有约35%被发电机组转化为电能，30%—35%随高温烟气排出（排烟温度达550℃），20%—25%被发电机冷却水带走，通过机身散热等其他损失占10%，排气余热和冷却水损失的能量比有用能量还多。占燃气发电机燃料近35%热能的烟气余热资源基本上被白白浪费掉。我公司针对这一工况，充分利用瓦斯发电机组烟气余热，安装炫风节能RGZFQ-X-X瓦斯发电机组配套的余热锅炉，产生的蒸汽可以带动汽轮机组二次发电，或者供暖及矿山坑道井口保温等。

For gas generator sets, only about 35% of the energy of gas fuel is converted into electrical energy by the generator set, 30-35% is discharged with high-temperature flue gas (exhaust temperature reaches 550 ℃), 20-25% is taken away by generator cooling water, and other losses such as heat dissipation through the body account for 10%. Exhaust waste heat and cooling water lose more energy than useful energy. The waste heat resources of flue gas, which account for nearly 35% of the thermal energy of gas generator fuel, are basically wasted in vain. Our company aims to fully utilize the waste heat from the flue gas of the gas generator set in this working condition, and install a waste heat boiler that is matched with the RGZFQ-X-X gas generator set. The generated steam can drive the steam turbine set for secondary power generation, or for heating and insulation of the mine tunnel wellhead.

传热效率高，节能效果显著。由于热管内部是真空的，管内工质汽、液相变传热的热阻很小，具有很高的导热能力。

High heat transfer efficiency and significant energy-saving effect. Due to the vacuum inside the heat pipe, the thermal resistance of the vapor liquid phase change heat transfer of the working fluid inside the pipe is very small, and it has high thermal conductivity.

安全可靠可长期连续运行。常规余热回收设备一般都是间壁式换热，冷热流体分别在器壁的两侧流过，任何一根管壁损坏都会造成泄漏，甚至停产。而由热管组成的热管余热回收装置，则是二次间壁换热，即热流体的热量要通过热管的加热段的管壁和冷凝段的管壁才能传到冷流体，而热管一般不可能在加热段和冷凝段同时破坏，所以，大大增强了设备运行的可靠性。

Safe and reliable for long-term continuous operation. Conventional waste heat recovery equipment generally uses wall to wall heat exchange, with cold and hot fluids flowing through both sides of the wall. Any damage to the wall of a pipe can cause leakage or even shutdown. The heat pipe waste heat recovery device composed of heat pipes is a secondary wall heat exchange, which means that the heat of the hot fluid can only be transferred to the cold fluid through the wall of the heating section and the condensing section of the heat pipe. However, the heat pipe is generally impossible to be damaged in both the heating and condensing sections, greatly enhancing the reliability of equipment operation.

管壁温度可调，通过调整热管冷热段换热面积改变热管表面工作温度，避免酸露点腐蚀。

The temperature of the pipe wall can be adjusted, and the surface working temperature of the heat pipe can be changed by adjusting the heat exchange area of the cold and hot sections of the heat pipe to avoid acid dew point corrosion.

清灰方便。该装置两侧设有快开清灰门，清灰方便。

Easy to clean ash. The device is equipped with quick opening ash cleaning doors on both sides, making ash cleaning convenient.

热管余热回收器单支热管可更换。

The single heat pipe of the heat pipe waste heat recovery device can be replaced.
