对于瓦斯发电机组，我们了解的内容并不多，所以为了让大家更多的了解它，我们从瓦斯发电机组余热回收的工作原理了解起来。

　　For the gas generator set, we do not know much, so in order to let you know more about it, we understand the working principle of waste heat recovery from the gas generator set.

　　在瓦斯发电机组排气系统安装热管余热回收装置，即热管空预器（热风利用）或热管换热器（热水利用）或热管蒸发器（低压饱和蒸汽利用），通过热动力循环设备（即大功率风机或热水利用管道循环泵或蒸汽管道）将低温交换介质（空气或者软化水）送到余热回收装置，经加热的低温交换介质变成热源直接或者再次交换后输送给终端客户使用。

　　Gas generator exhaust system installed in the heat pipe waste heat recovery unit, the heat pipe air preheater (hot air use) or (using) hot water or heat pipe evaporator heat pipe heat exchanger (low pressure saturated steam utilization), through thermodynamic cycle equipment (i.e. high power fan or hot water circulating pump use pipe or steam pipe) will exchange medium (air or demineralized water) at low temperature to waste heat recovery unit, After heating the low temperature exchange medium into a heat source directly or exchange again after delivery to the end customer for use.

　　余热回收的方式根据各个企业所需要的热源不同有空气置换余热、软化水置换余热产生热水以及软化水置换余热产生蒸汽三种。余热回收后的主要用途有以下几种：

　　According to the different heat sources needed by various enterprises, there are three ways of waste heat recovery: air replacement waste heat, softened water replacement waste heat to produce hot water, and softened water replacement waste heat to produce steam. The main uses of waste heat recovery are as follows:

　　余热制冷：目前广泛采用溴化锂吸收式制冷。用热管蒸发器吸收低浓度瓦斯发电机组余热回收的热量。

　　Waste heat refrigeration: lithium bromide absorption refrigeration is widely used at present. Heat pipe evaporator is used to absorb heat recovered from waste heat of low concentration gas generator set.

　　余热发电：通过多台瓦斯发电机组尾气的余热回收，安装热管蒸发器，产生的饱和蒸汽并往后拖动汽轮机组进行二次发电，发电后的冷凝水亦可制冷或者供暖，给企业带来可观的经济效益。

　　Waste heat power generation: through the waste heat recovery of exhaust gas of several gas generator sets, the heat pipe evaporator is installed to generate saturated steam and drag the steam turbine set backward for secondary power generation. The condensed water after power generation can also be refrigerated or heated, bringing considerable economic benefits to the enterprise.

　　煤矿巷道暖井（风井供热风）：在北方的冬季，煤矿风井巷道都需要热风炉暖井。把低浓度瓦斯发电机组产生的高温尾气经过热管空预器，将冷空气加热，可以得到高温热风通过烟道与风井处得热管空预器再次换热后的热空气送入风井，从而降低井下热风炉的热量输出，节约电能。

　　Coal mine roadway heating shaft (air shaft heating air) : in the northern winter, coal mine air shaft roadway needs hot stove heating shaft. By heating the cold air through the heat pipe air preheater and passing the high temperature tail gas generated by the low-concentration gas generator set, the high temperature hot air can be sent to the air shaft through the flue and the air shaft to obtain the hot air after the heat exchange by the heat pipe air preheater again, so as to reduce the heat output of the underground hot blast stove and save electric energy.

　　烘干、采暖和洗浴用热源：企业生产工艺中的烘干、采暖和洗浴常年需要热源。在发电机组烟道出口加装一台热管换热器（热管省煤器），通过热水循环泵几个低温水送到热管换热器，经过热交换的软化水为热源（90℃以上）供给企业生产使用，冷却后的软化水在返回热管换热器，如此往复循环。

　　Heat source for drying, heating and bathing: the drying, heating and bathing in the production process of the enterprise need heat source all the year round. A heat pipe heat exchanger (heat pipe economizer) is installed at the flue outlet of the generator set, and several low temperature water is sent to the heat pipe heat exchanger through the hot water circulation pump. The softened water through the heat exchange is supplied to the enterprise for production and use (above 90℃), and the softened water after cooling is returned to the heat pipe heat exchanger, and so on.
