焦爐煤氣發電機組的工作原理是利用焦爐煤氣作為燃料,通過內燃機轉化熱能為機械能,再經過發電機將機械能轉化為電能。
The working principle of a coke oven gas generator set is to use coke oven gas as fuel, convert heat energy into mechanical energy through an internal combustion engine, and then convert mechanical energy into electrical energy through a generator.
具體的工作原理如下:
The specific working principle is as follows:
1. 煤氣凈化:,焦爐產生的煤氣需要通過凈化系統進行凈化處理,去除其中的雜質和硫化物等有害物質,以保護發電機組的正常運行。
1. Gas purification: Firstly, the gas generated by the coke oven needs to be purified through a purification system to remove impurities and harmful substances such as sulfides, in order to protect the normal operation of the power generation unit.

2. 混合氧氣:清潔的煤氣與一定比例的氧氣混合,以提高燃燒效率,并且適當調節混合氣的成分,以確保燃燒過程中的穩定性。
2. Mixed oxygen: Clean gas is mixed with a certain proportion of oxygen to improve combustion efficiency, and the composition of the mixed gas is appropriately adjusted to ensure stability during the combustion process.
3. 內燃機燃燒:混合氣進入內燃機,通過噴油器噴入燃燒室。在燃燒室內,混合氣與點火裝置產生的火花相接觸,引發燃燒反應。燃燒過程中,煤氣的能量被釋放,產生高溫和高壓的燃燒氣體。
3. Internal combustion engine combustion: The mixture enters the internal combustion engine and is injected into the combustion chamber through an injector. In the combustion chamber, the mixture comes into contact with the spark generated by the ignition device, triggering a combustion reaction. During combustion, the energy of gas is released to produce high temperature and high pressure combustion gas.
4. 內燃機驅動:燃燒氣體的高溫和高壓推動活塞往復運動,通過連桿和曲軸將往復運動轉換為旋轉運動。這樣內燃機就將燃料的化學能轉化為機械能。
4. Internal combustion engine drive: The high temperature and high pressure of the combustion gas drive the piston to move back and forth, converting the reciprocating motion into rotary motion through the connecting rod and crankshaft. In this way, the internal combustion engine converts the Chemical energy of the fuel into mechanical energy.
5. 發電機發電:內燃機通過連接的軸將旋轉運動傳遞給發電機,發電機內的轉子在磁場中轉動產生感應電動勢,使得電荷在導線內流動,產生電能。這樣機械能就被轉化為電能。
5. Generator power generation: The internal combustion engine transmits rotational motion to the generator through a connected shaft, and the rotor inside the generator rotates in a magnetic field to generate induced electromotive force, causing charges to flow inside the wire and generate electrical energy. In this way, mechanical energy is converted into electrical energy.
6. 輸電和利用:發電機產生的電能經過變壓器升壓后進入輸電系統,然后分配給需要使用電能的設備或者注入電網供其他用戶使用。
6. Transmission and utilization: The electric energy generated by the generator enters the Electric power transmission after being boosted by the transformer, and then is distributed to the equipment that needs to use the electric energy or injected into the power grid for use by other users.
總之,焦爐煤氣發電機組利用焦爐煤氣的化學能,經過凈化、燃燒、驅動和發電等過程,將煤氣燃料轉化為電能。這種方式可以有效回收焦爐廢氣,并且節約能源,具有環保和經濟的優勢。
In a word, the coke oven gas generator unit uses the Chemical energy of coke oven gas to convert gas fuel into electric energy through purification, combustion, driving and power generation. This method can effectively recover coke oven exhaust gas and save energy, with environmental and economic advantages.
