Characteristics of two types of coke ovens

Characteristics and Applications of Channel Coke Ovens and Horizontal Coke Ovens

What is a coke oven?

A coke oven is a piece of equipment used to produce coke, which is widely used in the metallurgical, chemical and energy industries.

Coke ovens heat fuels such as coal to high temperatures through high temperature, causing pyrolysis and carbonization reactions to produce coke as the main product.

Coke is an important metallurgical raw material used in ironmaking, steelmaking and other metal smelting processes, and is also used as a chemical raw material and energy source.

Types of Coke Ovens

Coke ovens are usually categorized into two types: horizontal coke ovens and vertical coke ovens.

Horizontal Coke Ovens

Horizontal coke ovens are a common type of coke oven, also known as horizontal coke ovens or flat-bottomed coke ovens. Its design is characterized by the horizontal placement of the oven body and the horizontal diffusion and pyrolysis of coal inside the oven.

Components of a Horizontal Coke Oven

Horizontal coke ovens usually consist of an oven body, an oven floor, an oven chamber, an oven door and a coke discharge system. These parts are commonly used in coke ovens with silica bricks, refractory castables, insulating bricks composition.

Furnace body is the main structure of the coke oven, which is usually made of silicon bricks and steel plates, and can withstand high temperature and pressure.
The bottom of the furnace is the bottom of the furnace chamber, which is used to collect coke and slag.
The furnace chamber is the main area for coal pyrolysis and carbonization, and the gas is discharged through the outlet at the top of the chamber.
The door of the furnace is used for loading and unloading coal and coke, as well as for servicing and cleaning.

Working Principle of Horizontal Coke Oven

The working principle of Horizontal Coke Oven is that the coal is stacked evenly inside the furnace chamber, and air is injected through the air outlet at the bottom, so that the coal undergoes pyrolysis and carbonization at high temperature, and coke is finally produced.
The coal gas and flue gas are discharged from the gas outlet at the top of the furnace and are treated accordingly to obtain valuable by-products.

In the construction and operation of horizontal coke ovens, commonly used types of refractory bricks, including coke oven silica bricks, high alumina bricks, and Fireclay bricks, are used to build the refractory lining of the furnace body and chamber to withstand high temperatures and chemical attack.

Horizontal coke oven is a common and important type of coke oven with the advantages of high capacity, high quality coke and flexible operation. It plays an important role in metallurgy and chemical industry, providing important raw materials and energy for steel and chemical industries.

Channel Coke Oven

The Channel Coke Oven is a common type of coke oven, also known as a shaft or vertical oven. Its design is characterized by the vertical placement of the furnace body, in which coal is pyrolyzed and carbonized from top to bottom.

Components of a Channel Coke Oven

Trough coke oven usually consists of furnace body, furnace bottom, hearth, furnace throat and coke discharge system.
The furnace body is the main structure of the coke oven, which is made of refractory bricks and steel plates, and can withstand high temperature and pressure.
The bottom of the furnace is the bottom of the coke oven, which is used to collect coke and slag.
The hearth is the main area for coal pyrolysis and carbonization, and the gas is discharged through the outlet at the top of the hearth.
The furnace throat is used for loading and unloading coal and coke, as well as for maintenance and cleaning.
The coke discharge system is used to periodically discharge the coke generated in the furnace.

Working Principle of Trough Coke Oven

The working principle of the Trough Coke Oven is that coal is loaded from the furnace throat into a coal chute at the top of the furnace chamber, where it is gradually lowered through the high temperature zone for pyrolysis and charring to produce coke.
The gas and flue gas are discharged from the gas outlet at the top of the hearth and are treated accordingly to obtain valuable by-products.

Applications of Coke Ovens

Coke ovens have a wide range of applications in areas such as the steel and chemical industries. It is a common type of coke oven in the ironmaking industry and is used to produce high-quality coke for use as ironmaking charge. Coke ovens are also used to produce chemicals, energy and other carbon products.

The types of refractory bricks commonly used in the construction and operation of coke ovens include silica bricks for coke ovens, high alumina bricks, and refractory clay bricks. Among them, silicon bricks for coke ovens account for 60-70% of the refractory bricks in the construction of coke ovens. Refractory materials are used to construct the refractory lining of the furnace and hearth to withstand high temperatures and chemical attack.

Trough coke oven is a common and important type of coke oven that offers advantages such as high capacity, high quality coke and operational flexibility. It plays an important role in the metallurgical and chemical industries, providing important raw materials and energy for the steel and chemical industries.
