瓦斯发电机组对瓦斯的要求
开发利用瓦斯气具有保护全球环境,改善煤矿安全和增加新能源等多重功效。为合理利用瓦斯气变害为用瓦斯发动机并配套成发电机组:这既鰩决了抽排气对大气环境的污染。又收了瓦斯气这一绿色能源。
The development and utilization of gas has multiple effects such as protecting the global environment, improving coal mine safety and increasing new energy. In order to make reasonable use of the gas to change the harm into using gas engine and form a complete set of generator set, this will not only solve the pollution of the exhaust gas to the atmospheric environment. The green energy of gas is also collected.
利用瓦斯气进行发电,这是变废喂饱的一条经济,有效途径。况且国内拥有丰富的煤层气资源,该机可用瓦斯气(矿井气)、煤层气作为燃料也可用沼气,天然气等燃气作为燃料使用,可配成发电机组或其他都鼓励输出,满足不同客户的要求。
It is an economic and effective way to use gas to generate electricity. Moreover, China has rich resources of coalbed methane. The machine can use gas (mine gas), coalbed methane as fuel, biogas, natural gas and other gas as fuel, and can be equipped with power generation units or other incentives to output to meet the requirements of different customers.
瓦斯发电机组对瓦斯的要求:
Requirements of gas generator set for gas:
在距离燃气机组燃气进气阀1m内
Within 1m from the gas inlet valve of gas turbine
1、瓦斯温度≤40°C;
1. Gas temperature ≤ 40 ° C;
2、瓦斯压力3~20kpa,压力变化率≤1kpa/min;.
2. Gas pressure 3~20kpa, pressure change rate ≤ 1kpa/min
3、H2S≤200mg/Nm;
3、H2S≤200mg/Nm;
4、对于CH4体积含量≤30%的瓦斯,CH4与02体积含量之和≥28%,02体积含量≥16%;5、瓦斯中水分含量≤40mg/Nm;
4. For gas with CH4 volume content ≤ 30%, the sum of CH4 and 02 volume content ≥ 28%, and 02 volume content ≥ 16%; 5. Moisture content in gas ≤ 40mg/Nm;
6、杂质粒度≤5um,杂质含量≤30mg/Nm;
6. Impurity particle size ≤ 5um, impurity content ≤ 30mg/Nm;
如果可燃气体中含硫及氨成分较高,不仅会严重腐蚀火花塞电极,而且会使机油中的酸值增加,腐蚀机组内部零件,同时易于生成沉淀物,增加对发动机的磨损和腐蚀。
If the sulfur and ammonia content in the combustible gas is high, it will not only seriously corrode the spark plug electrode, but also increase the acid value in the engine oil, corrode the internal parts of the unit, and at the same time, it is easy to generate sediment, which will increase the wear and corrosion of the engine.
