1. Introduction to Coke Oven Gas
Coke oven gas, also known as Coke Oven Gas (COG) in English, belongs to high calorific value gas, crude gas or raw gas due to its high combustible components. It refers to a combustible gas produced by mixing several types of bituminous coal into coking coal, which is then subjected to high-temperature dry distillation in a coking furnace to produce 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 coal used for coking and the conditions of the coking process. Generally, 300-350m3 of coke oven gas can be produced per ton of dry coal (standard state). Its main components are hydrogen (55%~60%) and methane (23%~27%), in addition to a small amount of carbon monoxide (5%~8%), unsaturated hydrocarbons above C2 (2%~4%), carbon dioxide (1.5%~3%), oxygen (0.3%~0.8%), and nitrogen (3%~7%). Among them, hydrogen, methane, carbon monoxide, and unsaturated hydrocarbons above C2 are combustible components, while carbon dioxide, nitrogen, and oxygen are non combustible components.

4. What is the calorific value of coal gas? The calorific value of gas refers to the amount of heat that can be released by a certain volume or mass of gas, also known as the heat generation of gas. There are various units, among which megajoules per standard cubic meter are the most commonly used. Coke oven gas is a mixture mainly composed of hydrogen (55%~60%) and methane (23%~27%). The calorific value of hydrogen is about 1.4 × 10 ^ 8 joules/kilogram (or 2.82 × 10 ^ 5 joules/mole), while the calorific value of methane is about 50200 kilojoules/kilogram (or 35900 kilojoules/cubic meter). 1. Coke oven gas, also known as coke oven gas, is composed of hydrogen, methane, carbon monoxide, unsaturated hydrocarbons above C2, carbon dioxide, oxygen, and nitrogen. Among them, hydrogen, methane, carbon monoxide, and unsaturated hydrocarbons above C2 are combustible components, while carbon dioxide, nitrogen, and oxygen are non combustible
2. The calorific value range of coke oven gas is between 16720 and 18810 kilojoules per cubic meter, with a relatively high proportion of combustible components, accounting for about 90%
3. Coke oven gas, also known as Coke Oven Gas (COG) in English, is a high calorific value gas, also known as crude gas or raw gas. It is a coking coal made from several types of bituminous coal, and the combustible gas produced by high-temperature dry distillation in the coking furnace is a by-product of the coking industry. Due to differences in the quality of coking coal and coking process conditions, the yield and composition of coke oven gas may vary. Normally, one ton of dry coal can produce approximately 300 to 350 cubic meters (standard st
