燃气发电机组为什么被用户喜爱?
燃气发电组为什么被用户喜爱:首先就是天然气输送不受气候影响,可以就地储存,城市或区域配有一定规模天然气分布式能源供电系统,自主发电能力提高,较单纯依赖大电网供电系统具有更高的安全性。
Why are gas-fired power generation units favored by users? Firstly, natural gas transmission is not affected by climate and can be stored on-site. Cities or regions are equipped with a certain scale of natural gas distributed energy power supply system, which improves their independent power generation capacity and has higher safety than relying solely on large power grid power supply systems.
其次,天然气分布式能源项目可成为终端可调节的发电系统,对天然气和电力具有双重”削峰填谷”作用,有效缓解天然气冬夏季峰谷差,提高夏季燃气设施的利用效率,增强供气系统安全性。
Secondly, natural gas distributed energy projects can become terminal adjustable power generation systems, which have a dual "peak shaving and valley filling" effect on natural gas and electricity, effectively alleviating the peak valley difference of natural gas in winter and summer, improving the utilization efficiency of gas facilities in summer, and enhancing the safety of gas supply systems.
然后,天然气分布式能源能实现能源的梯级利用,充分利用发电余热,就地供电,可减少电力与热力长距离输送的损耗,能源综合利用率在80%以上,超过大型煤电发电机组一倍,同时节约电网,热力管网输送环节的投资费用,产生巨大地经济效益。
Then, natural gas distributed energy can achieve cascade utilization of energy, fully utilize the waste heat of power generation, provide on-site power supply, reduce the loss of long-distance transmission of electricity and heat, and achieve a comprehensive energy utilization rate of over 80%, which is twice that of large coal-fired power generation units. At the same time, it saves investment costs in the power grid and heat pipeline transmission links, generating huge economic benefits.
最后,采用清洁一次性能源的分布式功能系统,可大幅度减少二氧化碳等污染排放。十二五规划预计的天然气分布式能源装机5000万千瓦,相当于减少1亿千瓦燃煤装机,减少消耗2亿吨煤炭,减排4亿吨二氧化碳。
Finally, adopting a distributed functional system of clean disposable energy can significantly reduce pollution emissions such as carbon dioxide. The 12th Five Year Plan predicts a natural gas distributed energy installed capacity of 50 million kilowatts, which is equivalent to reducing 100 million kilowatts of coal-fired installed capacity, reducing coal consumption by 200 million tons, and reducing carbon dioxide emissions by 400 million tons.
除此之外,燃气发电机组在环境适应能力方面,也比传统柴油发电机组要强。同时注意事项也不能少:
In addition, gas-fired generator sets have stronger environmental adaptability than traditional diesel generator sets. At the same time, precautions must also be taken:
1、燃气发电机组机房应远离明火区域;
1. The gas generator room should be kept away from open flame areas;
2、燃气发电机组机房应宽敞、明亮且要求安装换气扇以保证良好的通风;
2. The gas generator room should be spacious, bright, and require the installation of ventilation fans to ensure good ventilation;
3、燃气发电机组安装时底盘与地基应用平垫铁找平。接触面积应在60%以上,且分布均匀;
3. When installing a gas generator set, the chassis and foundation should be leveled with flat pad iron. The contact area should be over 60% and evenly distributed;
4、室内安装照明、开关、线路及其电器应采用防爆措施,且固定牢固;
4. Indoor installation of lighting, switches, circuits, and their electrical appliances should adopt explosion-proof measures and be firmly fixed;
5、燃气发电机组机房内应符合消防要求,配备灭火器等消防器械;
5. The gas generator room should meet fire safety requirements and be equipped with fire extinguishers and other firefighting equipment;
6、燃气发电机组机房内安装可燃气体报警装置,可燃气体泄露时能及时发现;
6. Install combustible gas alarm devices in the gas generator room, which can detect combustible gas leaks in a timely manner;
7、60kw以下单台燃气发动机燃气管路的外部主要管道内径应不小于2吋,靠近发动机的部分内径应不小于1吋。60kw以上燃气发电机组则分别是3吋和两吋。且必须安装燃气阀门(不锈钢球阀)、型放水阀、防回火装置,燃气管路焊接完成应清理焊渣(用高压空气);
7. The inner diameter of the external main pipeline of the gas pipeline of a single gas engine below 60kw should not be less than 2 inches, and the inner diameter of the part near the engine should not be less than 1 inch. Gas generators with a power of over 60kW are 3 inches and 2 inches respectively. And gas valves (stainless steel ball valves), type drain valves, and anti backfire devices must be installed. After welding the gas pipeline, welding slag should be cleaned (using high-pressure air);
8、燃气必须脱硫、脱水、除尘,其中含流量≤0.25Nm3,氢气≤10%
8. Gas must undergo desulfurization, dehydration, and dust removal, with a flow rate of ≤ 0.25Nm3 and hydrogen gas of ≤ 10%
