1. Classification by Combustion Flue Arrangement Characteristics
-
Two-part Type
The combustion flues of the regenerator are divided into two sections by the machine side and the coke side. One section features upward gas flow while the other has downward gas flow. A horizontal flue connects the tops of the vertical flues. Typical examples include the Type 66 Coke Oven.
-
Double-couple Type
Adjacent combustion flues in the regenerator are paired up, with one flue for upward gas flow and the other for downward gas flow. It is applied in Type 58, Type 80 and modern large-capacity coke ovens.
2. Classification by Heating Method
- Single-gas Heating Type
Coke ovens structurally designed to use only one type of gas for heating. It is further categorized into coke oven gas single-heating type and blast furnace gas single-heating type.
- Combined Heating Type
Coke ovens capable of heating with two different types of gas.
3. Classification by Coke Oven Gas Supply Mode
- Side-feed Type
Coke oven gas enters the vertical flues through horizontal brick gas ducts located on both sides of the coke oven.
- Bottom-injection Type
Coke oven gas enters the vertical flues through vertical brick gas ducts running from beneath the oven structure.
