焦化發(fā)電機(jī)組屬于高效利用工業(yè)廢氣的設(shè)備,具體為焦?fàn)t煤氣發(fā)電機(jī)組。
Coking power generation units are equipment that efficiently utilize industrial waste gas, specifically coke oven gas power generation units.
焦?fàn)t煤氣發(fā)電機(jī)組是一種將焦?fàn)t煤氣轉(zhuǎn)化為電能的設(shè)備。焦?fàn)t煤氣是在煉焦過(guò)程中產(chǎn)生的可燃性氣體,主要由氫氣、甲烷、一氧化碳等可燃成分以及氮?dú)狻⒍趸嫉炔豢扇汲煞纸M成,具有熱值高、雜質(zhì)多等特點(diǎn)。焦?fàn)t煤氣發(fā)電機(jī)組通過(guò)預(yù)處理去除煤氣中的雜質(zhì),然后利用燃?xì)獍l(fā)動(dòng)機(jī)將煤氣的化學(xué)能轉(zhuǎn)化為機(jī)械能,再通過(guò)發(fā)電機(jī)將機(jī)械能轉(zhuǎn)化為電能。
Coke oven gas generator set is a device that converts coke oven gas into electrical energy. Coke oven gas is a combustible gas produced during the coking process, mainly composed of combustible components such as hydrogen, methane, and carbon monoxide, as well as non combustible components such as nitrogen and carbon dioxide. It has the characteristics of high calorific value and high impurities. The coke oven gas generator unit removes impurities from the gas through pretreatment, and then uses a gas engine to convert the chemical energy of the gas into mechanical energy, which is then converted into electrical energy through a generator.
焦化發(fā)電機(jī)組主要依賴于焦化過(guò)程中產(chǎn)生的煤氣進(jìn)行發(fā)電,其應(yīng)用領(lǐng)域主要集中在鋼鐵、化工等行業(yè),為其提供所需的電力和熱能。與瓦斯發(fā)電機(jī)組相比,焦化發(fā)電機(jī)組更多地依賴于煤炭資源,其環(huán)保性能相對(duì)較差,碳排放量較高,但在煤炭資源豐富的地區(qū)具有較高的經(jīng)濟(jì)性和實(shí)用性。
Coking power generation units mainly rely on the gas generated during the coking process for power generation, and their application areas are mainly concentrated in industries such as steel and chemical, providing them with the required electricity and heat energy. Compared with gas power generation units, coking power generation units rely more on coal resources, with relatively poor environmental performance and higher carbon emissions. However, they have higher economic and practical viability in areas with abundant coal resources.
焦化發(fā)電機(jī)組,是火電設(shè)備還是余熱發(fā)電設(shè)備?
Is the coking generator set a thermal power equipment or a waste heat power generation equipment?
余熱發(fā)電設(shè)備
Waste heat power generation equipment
焦化發(fā)電機(jī)組屬于余熱發(fā)電設(shè)備,特別是干熄焦余熱發(fā)電機(jī)組,它利用焦炭的余熱通過(guò)轉(zhuǎn)換變成電能。
Coking power generation units belong to waste heat power generation equipment, especially dry quenching waste heat power generation units, which use the waste heat of coke to convert it into electrical energy.
干熄焦余熱發(fā)電技術(shù)是指采用惰性氣體將紅焦降溫冷卻的一種熄焦方法,其熄焦過(guò)程中的余熱又通過(guò)轉(zhuǎn)換變成電能。合理利用干熄焦余熱發(fā)電技術(shù),既能有效吸收紅焦的熱量,節(jié)約水資源,又能獲取日常工作所需的電力,實(shí)現(xiàn)低碳生產(chǎn)。例如,山西中陽(yáng)鋼鐵有限公司的90萬(wàn)噸焦化干熄焦余熱發(fā)電機(jī)組成功并網(wǎng)發(fā)電,該項(xiàng)目具有節(jié)能、環(huán)保、提高焦炭質(zhì)量三重效益。此外,鄂托克旗紅纓煤焦化公司也利用干熄焦余熱發(fā)電技術(shù),實(shí)現(xiàn)年發(fā)電1.5億度。這些案例表明,焦化發(fā)電機(jī)組是余熱發(fā)電設(shè)備的一種。
Dry quenching coke waste heat power generation technology refers to a coke quenching method that uses inert gas to cool down red coke, and the waste heat during the quenching process is converted into electrical energy. Reasonable utilization of dry quenching waste heat power generation technology can effectively absorb the heat of red coke, save water resources, and obtain the electricity needed for daily work, achieving low-carbon production. For example, the 900000 ton coking dry quenching waste heat power generation unit of Shanxi Zhongyang Iron and Steel Co., Ltd. has been successfully connected to the grid for power generation. This project has the triple benefits of energy conservation, environmental protection, and improving coke quality. In addition, the Hongying Coal Coking Company in Etuoke Banner also utilizes dry quenching waste heat power generation technology to achieve an annual power generation of 150 million kWh. These cases indicate that coking power generation units are a type of waste heat power generation equipment.
