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.

The specific working principle is as follows:

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. 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. 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. 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. 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. 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.

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.
