Name: China Coke Oven Manufacturers, Suppliers and Factory - Good Price Coke Oven - Luming New Materials
Brand: Luming
SKU: 277429791

A coke oven is a pyrolysis furnace used in the coking process, which involves heating coal in isolation from air to high temperatures (typically 1000–1100°C), allowing volatile components in the coal to escape, leaving behind high-carbon solid coke. Coke appears gray, hard, and porous, with carbon content mainly above 90%, used in metallurgy, chemical industries, and other fields.

Coke ovens mainly consist of the following parts:

1.Coking Chambers: These are the core components of coke ovens, used for loading coal and conducting carbonization. Modern coke ovens typically have dozens to over a hundred coking chambers arranged side by side.

2.Heating Chambers: Located on both sides of the coking chambers, they provide heat for the carbonization process by burning coke oven gas or external fuels.

3.Regenerators: Utilize waste gas heat to preheat combustion air and gas, improving thermal efficiency.

4.Flue System: Collects and transports combustion waste gases.

5.Coal Charging and Coke Discharging Equipment: Including coal charging cars, coke pushing machines, coke guide cars, and other mechanical equipment.

Our company is a specialized enterprise dedicated to the research, development, and production of high-quality sintered refractory materials for coke ovens.
