燃氣發電機組為什么被用戶喜愛?
燃氣發電組為什么被用戶喜愛:首先就是天然氣輸送不受氣候影響,可以就地儲存,城市或區域配有一定規模天然氣分布式能源供電系統,自主發電能力提高,較單純依賴大電網供電系統具有更高的安全性。
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,天然氣分布式能源項目可成為終端可調節的發電系統,對天然氣和電力具有雙重”削峰填谷”作用,有效緩解天然氣冬夏季峰谷差,提高夏季燃氣設施的利用效率,增強供氣系統安全性。
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,天然氣分布式能源能實現能源的梯級利用,充分利用發電余熱,就地供電,可減少電力與熱力長距離輸送的損耗,能源綜合利用率在80%以上,超過大型煤電發電機組一倍,同時節約電網,熱力管網輸送環節的投資費用,產生巨大地經濟效益。
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,采用清潔一次性能源的分布式功能系統,可大幅度減少二氧化碳等污染排放。十二五規劃預計的天然氣分布式能源裝機5000萬千瓦,相當于減少1億千瓦燃煤裝機,減少消耗2億噸煤炭,減排4億噸二氧化碳。
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,燃氣發電機組在環境適應能力方面,也比傳統柴油發電機組要強。同時注意事項也不能少:
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、燃氣發電機組機房應遠離明火區域;
1. The gas generator room should be kept away from open flame areas;
2、燃氣發電機組機房應寬敞、明亮且要求安裝換氣扇以保證良好的通風;
2. The gas generator room should be spacious, bright, and require the installation of ventilation fans to ensure good ventilation;
3、燃氣發電機組安裝時底盤與地基應用平墊鐵找平。接觸面積應在60%以上,且分布均勻;
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、室內安裝照明、開關、線路及其電器應采用防爆措施,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、燃氣發電機組機房內應符合消防要求,配備滅火器等消防器械;
5. The gas generator room should meet fire safety requirements and be equipped with fire extinguishers and other firefighting equipment;
6、燃氣發電機組機房內安裝可燃氣體報警裝置,可燃氣體泄露時能及時發現;
6. Install combustible gas alarm devices in the gas generator room, which can detect combustible gas leaks in a timely manner;
7、60kw以下單臺燃氣發動機燃氣管路的外部主要管道內徑應不小于2吋,靠近發動機的部分內徑應不小于1吋。60kw以上燃氣發電機組則分別是3吋和兩吋。且必須安裝燃氣閥門(不銹鋼球閥)、型放水閥、防回火裝置,燃氣管路焊接完成應清理焊渣(用高壓空氣);
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、燃氣必須脫硫、脫水、除塵,其中含流量≤0.25Nm3,氫氣≤10%
8. Gas must undergo desulfurization, dehydration, and dust removal, with a flow rate of ≤ 0.25Nm3 and hydrogen gas of ≤ 10%
