Detailed content:

1、 Composition of coke oven gas: coke oven gas, also known as coke oven gas, English name is Coke Oven Gas (COG). Due to its many combustible components, it belongs to high calorific value gas, crude gas or raw gas. It refers to a combustible gas produced by preparing several types of bituminous coal into coking coal, which is subjected to high-temperature dry distillation in the coking furnace, while producing coke and tar products. It is a byproduct of the coking industry. Coke oven gas is a mixture, and its yield and composition vary depending on the quality of coking coal and coking process conditions. Generally, each ton of dry coal can produce 300-350m3 of coke oven gas (standard state). Its main components are hydrogen (55%~60%) and methane (23%~27%), in addition, it also contains a small amount of carbon monoxide (5%~8%), unsaturated hydrocarbon above C2 (2%~4%), carbon dioxide (1.5%~3%), oxygen (0.3%~0.8%), and nitrogen (3%~7%). Hydrogen, methane, carbon monoxide and unsaturated hydrocarbon above C2 are combustible components, while carbon dioxide, nitrogen and oxygen are non combustible components.

2、 Characteristics of coke oven gas:

1. The calorific value of coke oven gas is high at 16720-18810kJ/m, and the combustible composition is relatively high (about 90%);

2. Coke oven gas is a colorless and odorless gas;

3. Coke oven gas is toxic due to its presence of CO and a small amount of H2S;

4. Coke oven gas contains more hydrogen, has a fast combustion speed, and a shorter flame;

5. If the purification of coke oven gas is not good, it will contain a lot of tar and naphthalene, which will block pipes and fittings, making it difficult to adjust the fire;

6. The ignition temperature is 600~650 ℃.

3、 Characteristics of coke oven gas hot blast stove burner:

(1) The solar term. The coke oven gas burner adopts a stable flame disc structure, which forcibly changes the angle of combustion air injection and fully mixes with the gas for combustion, resulting in the generation of carbon dioxide and water to achieve energy-saving goals.

(2) Automation control system. The coke oven gas burner is designed with automatic ignition, flameout protection, temperature automatic control, leakage protection, and gas cut-off functions. It can be connected to the central control room DCS to achieve remote control functions.

(3) The coke oven gas burner can achieve multi fuel mixed combustion, high coke gas mixed combustion, coal powder and gas mixed combustion, and fuel and gas mixed combustion. For more information, please call (WeChat synchronization): 15713691937.

(4) Design and construction of dust removal equipment for hot air furnaces.

4、 Coke oven gas burners are mainly used in fields such as hot air furnaces, dryers, rotary kilns, fluidized bed furnaces, and boilers.
