        燃氣輪機與燃氣發(fā)電機組的對比

        返回 2020.10.09 來(lái)源:http://m.elmasticar.com 0
        燃氣內燃機的發(fā)電效率通常在30%-40%之間,比較常見(jiàn)的機型一般可以達到35%。燃氣內燃機更突出的優(yōu)點(diǎn)正是發(fā)電效率比較高,其次是設備集成度高,安裝快捷,對于氣體中的粉塵要求不高,基本不需要水,設備的單位千瓦造價(jià)也比較低。但是內燃機也有一些不足的地方,首先,內燃機燃燒低熱值燃料時(shí),機組出力明顯下降,一臺燃燒低熱值8000大卡/立方米天然氣燃料的500千瓦級燃氣內燃發(fā)電機組,在使用低熱值4000大卡/立方米的焦化煤氣時(shí),出力可能下降到350~400kW左右。
        The power generation efficiency of gas-fired internal combustion engine is usually between 30% and 40%, and the more common models can reach 35%. The most prominent advantage of gas-fired internal combustion engine is high power generation efficiency, followed by high equipment integration, fast installation, low requirements for dust in gas, basically no water, and the unit kilowatt cost of the equipment is relatively low. However, the internal combustion engine also has some shortcomings. First of all, when the internal combustion engine burns low calorific value fuel, the unit output drops obviously. A 500 kW gas-fired internal combustion generator set burning 8000 kcal / m3 natural gas fuel with low calorific value may drop to 350-400kw when using coking gas with low calorific value of 4000 kcal / m3.
        此外,內燃機需要頻繁更換機油和火花塞,消耗材料比較大,也影響到設備的可用性和可靠性?xún)蓚€(gè)主要設備利用指標,對設備利用率影響比較大,有時(shí)不得不采取增加發(fā)電機組臺數的辦法,來(lái)消除利用率低的影響。內燃機設備對焦化煤氣中的水分子含量和硫化氫比較敏感,可能導致硫化氫和水形成硫酸腐蝕問(wèn)題,需要采取一些必要措施加以克服。
        In addition, the internal combustion engine needs to change the engine oil and spark plug frequently, and the consumption of materials is relatively large, which also affects the availability and reliability of the two main equipment utilization indexes, and has a greater impact on the equipment utilization rate. Sometimes, it is necessary to increase the number of generating units to eliminate the impact of low utilization rate. Internal combustion engine equipment is sensitive to water molecular content and hydrogen sulfide in coking gas, which may lead to sulfuric acid corrosion of hydrogen sulfide and water, and some necessary measures should be taken to overcome it.
        焦化發(fā)電機組
        燃氣輪機比較適用于高含氫低熱值和氣體含雜質(zhì)較多的劣質(zhì)燃料,一些燃氣輪機甚至使用原油和高硫渣油燃料。燃氣輪機自身的發(fā)電效率不算很高,一般在30%~35%之間,但是產(chǎn)生的廢熱煙氣溫度高達450~550℃,可以通過(guò)余熱鍋爐再次回收熱能轉換蒸汽,驅動(dòng)蒸汽輪機再發(fā)一次電,形成燃氣輪機--蒸汽輪機聯(lián)合循環(huán)發(fā)電,發(fā)電效率可以達到45%~50%,一些大型機組甚至可以超過(guò)55%。
        Gas turbine is more suitable for the inferior fuel with high hydrogen content and low calorific value and gas containing more impurities. Some gas turbines even use crude oil and high sulfur residue fuel. The power generation efficiency of gas turbine itself is not very high, generally between 30% and 35%, but the temperature of waste heat flue gas generated is as high as 450 ~ 550 ℃, which can be recycled by waste heat boiler to convert steam, drive steam turbine to generate electricity again, and form gas turbine steam turbine combined cycle power generation. The power generation efficiency can reach 45% ~ 50%, and some large units can even exceed 55% 。
        采用燃氣輪機的優(yōu)勢相對比較多,首先是設備的可用性和可靠性都比較高,綜合利用率一般可以保持在90%;其次,對于燃料的適應性比較強,含硫、含塵高一點(diǎn)問(wèn)題都不大;再有就是發(fā)電出力一般不會(huì )減少,甚至因為燃料進(jìn)氣量增加而有所增加;此外,燃氣輪機功率密度大體積小,比較適合再移動(dòng),便于轉移運行現場(chǎng),這對于存在一些不確定性的焦化廠(chǎng)項目的焦化煤氣利用非常有利。但是,世上的事務(wù)有一利,必有一弊,沒(méi)有十全十美的事情。
        The advantages of using gas turbine are relatively more. Firstly, the availability and reliability of the equipment are relatively high, and the comprehensive utilization rate can generally be maintained at 90%; secondly, the adaptability of fuel is relatively strong, and the problems of high sulfur content and dust content are not obvious; thirdly, the power generation output will not decrease in general, even increased due to the increase of fuel intake; In addition, the gas turbine has large power density and small volume, which is suitable for re moving and easy to transfer the operation site, which is very beneficial to the utilization of coking gas in coking plant projects with some uncertainties. However, the affairs of the world have one advantage and one disadvantage. There is no perfect thing.
        燃氣輪機進(jìn)氣壓力比較大,越是發(fā)電效率高的機組燃料進(jìn)氣壓力越高,因為焦化煤氣本身沒(méi)有什么壓力,這就需要使用燃氣壓縮機,壓縮燃氣需要消耗大量的能量,影響到設備的實(shí)際輸出功率,一些項目甚至需要消耗燃氣輪機15%~20%的功率,對于聯(lián)合循環(huán)項目達到影響可能是10%~15%的輸出功率;采用聯(lián)合循環(huán)系統存在與蒸汽輪機相同的水資源條件要求,系統比較復雜,投資也比較大,同時(shí)搬遷也比較困難。
        The inlet pressure of gas turbine is relatively large, and the higher the unit with high power generation efficiency, the higher the fuel inlet pressure. Because coking gas itself has no pressure, it needs to use gas compressor. Compressing gas needs to consume a lot of energy, which affects the actual output power of the equipment. Some projects even need to consume 15% ~ 20% of the power of the gas turbine, which has an impact on the combined cycle project The impact may be 10% - 15% of the output power; the combined cycle system has the same water resource requirements as the steam turbine, which is more complex, more investment, and more difficult to relocate.
