Clay refractory bricks for coke ovens are mainly used in the following parts of coke ovens:

I. Regenerator

Regenerator checker brick: Clay refractory brick has good thermal shock stability and corrosion resistance, and is suitable for regenerator checker brick.

Regenerator single wall, main wall and partition wall: These parts are usually built with silicon bricks, but clay bricks can also be used on the outside to ensure the stability of the whole structure.

II. Small flue

Small flue lining brick: clay brick is used in small flue, mainly for heat insulation and protection.

III. Furnace door

Furnace door lining brick: the oven door of coke oven needs to be opened and closed frequently, and the temperature changes greatly, so clay brick, thermal insulation brick or cordierite brick is usually used for masonry.

IV. Furnace top

Furnace top lining brick: The temperature of the furnace top fluctuates greatly, and the thermal shock stability of clay brick makes it an ideal choice for furnace top lining brick.

V. Risers and bridge pipes

Lining brick of riser and bridge pipe: The temperature of these parts changes frequently, and the thermal shock stability of clay brick can effectively protect the equipment.

VI. Burners at both ends of the carbonization chamber

Furnace head: The furnace heads at both ends of the carbonization chamber change greatly in the process of opening and closing the furnace door, and are affected by dynamic load. Clay bricks, high alumina bricks or andalusite bricks are usually selected.

VII. Chimneys and CDQ devices

Chimney lining: Chimneys and CDQ devices are usually built with clay bricks to meet the requirements of corrosion resistance and heat insulation.

VIII. Other parts

Thermal insulation layer: In the filling layer at the top of the furnace, clay bricks can be used together with other thermal insulation materials (such as diatomite and vermiculite) to improve the thermal insulation effect.

Clay refractory bricks are widely used in these parts of coke ovens because of their good thermal shock stability and corrosion resistance.
