煤礦瓦斯發(fā)電，既可以有效地解決煤礦瓦斯事故、改善煤礦安全生產(chǎn)條件，又有利于增加潔凈能源供應(yīng)、減少溫室氣體排放，達到保護生命、保護資源、保護環(huán)境的多重目標(biāo)。安徽煤礦案例

　　Coal mine gas power generation can effectively solve coal mine gas accidents, improve coal mine safety production conditions, increase clean energy supply, reduce greenhouse gas emissions, and achieve multiple goals of protecting life, resources, and the environment. Anhui Coal Mine Case

　　對于瓦斯發(fā)電機組，燃氣燃料的能量只有約35%被發(fā)電機組轉(zhuǎn)化為電能，30%—35%隨高溫?zé)煔馀懦觯ㄅ艧煖囟冗_550℃），20%—25%被發(fā)電機冷卻水帶走，通過機身散熱等其他損失占10%，排氣余熱和冷卻水損失的能量比有用能量還多。占燃氣發(fā)電機燃料近35%熱能的煙氣余熱資源基本上被白白浪費掉。金瑞團隊針對這一工況，充分利用瓦斯發(fā)電機組煙氣余熱，安裝金瑞JR-WS瓦斯發(fā)電機組配套的余熱鍋爐，產(chǎn)生的蒸汽帶動汽輪機組二次發(fā)電。使礦井資源得到了充分利用，礦山環(huán)境得到有效保護，實現(xiàn)了企業(yè)的節(jié)約發(fā)展、清潔發(fā)展和可持續(xù)發(fā)展，創(chuàng)造了良好的經(jīng)濟、環(huán)保和社會綜合效益。

　　For gas generator sets, only about 35% of the energy from gas fuel is converted into electrical energy by the generator set, 30% -35% is discharged with high-temperature flue gas (exhaust temperature reaches 550 ℃), 20% -25% is taken away by the generator cooling water, and other losses such as heat dissipation through the body account for 10%. The energy lost from exhaust waste heat and cooling water is more than the useful energy. The waste heat resources from flue gas, which account for nearly 35% of the thermal energy generated by gas-fired generators, are basically wasted. The Jinrui team made full use of the waste heat from the flue gas of the gas generator set for this working condition, installed the waste heat boiler matched with the Jinrui JR-WS gas generator set, and generated steam to drive the steam turbine unit for secondary power generation. The mining resources have been fully utilized, the mining environment has been effectively protected, and the enterprise has achieved energy-saving, clean and sustainable development, creating good economic, environmental and social comprehensive benefits.

　　天然氣是地球上最豐富的燃料之一，國外權(quán)威機構(gòu)預(yù)言，天然氣將在21世紀取代石油，成為第二大能源。同時，天然氣也是發(fā)動機的優(yōu)質(zhì)燃料，它對發(fā)動機潤滑油品質(zhì)破壞性小，燃燒更充分，燃燒室內(nèi)沒有積炭和膠質(zhì)，因而可延長發(fā)動機的使用壽命，降低發(fā)動機的維修費用。氣體燃料發(fā)動機的排放指標(biāo)優(yōu)于汽油機和柴油機，同時燃氣發(fā)動機排出廢氣中顆粒排放物極少，對大氣污染程度小，能滿足國內(nèi)的發(fā)動機排放要求，有較好的環(huán)保效果。

　　Natural gas is one of the most abundant fuels on Earth, and authoritative foreign institutions predict that it will replace oil as the second largest energy source in the 21st century. At the same time, natural gas is also a high-quality fuel for engines. It has less destructive effect on the quality of engine lubricating oil, burns more thoroughly, and there is no carbon or gum buildup in the combustion chamber. Therefore, it can extend the service life of the engine and reduce maintenance costs. The emission standards of gas fuel engines are superior to gasoline engines and diesel engines. At the same time, gas engines emit very little particulate matter in the exhaust gas, which has a low degree of air pollution and can meet the domestic engine emission requirements, with good environmental protection effects.
