Checker bricks, also known as regenerator checker bricks or heat storage bricks, are a type of refractory brick used in regenerative combustion systems found in industries such as glassmaking and steel production. Checker bricks play an important role in the heat recovery process by storing and releasing heat as exhaust gases pass through the chambers during the cyclic operation of the regenerative system.
When in use, checker bricks are arranged in pairs with channels between them to allow for the flow of hot gas. During operation, one pair of bricks will absorb heat from the gas stream, while the other pair releases heat back into the gas stream before it exits the chimney. This process is then reversed periodically, with the roles of the two pairs of bricks switching.
Checker bricks need to have high thermal conductivity, excellent thermal shock resistance, and good mechanical strength. The quality of the checker bricks can significantly impact the efficiency and durability of the regenerative combustion system, which affects the overall energy consumption and cost of production.
1.Glass kiln
Lattice refractory bricks are often used to make inverted plates in glass kilns, so that glass blanks can be heated evenly, thereby improving production efficiency and product quality.
2.Metallurgical industry
Lattice refractory bricks can be used in high-temperature kilns, converters and other equipment in the metallurgical industry, such as electric arc furnaces and electric melting furnaces.
3.Steel industry
In the steel industry, lattice refractory bricks are often used in high-temperature equipment such as converters, electric furnaces, and heating furnaces to protect internal structural parts from heat damage.
4.Chemical industry
Lattice refractory bricks can be used in high-temperature equipment such as kilns, reactors, and furnace tubes in chemical plants to withstand the erosion of chemical substances and the reaction at high temperatures.
5.Other industries
Lattice refractory bricks can also be used in various fields that require the use of refractory materials, such as horizontal heating furnaces, floor heating furnaces, and household wall-hung furnaces.
To sum up, lattice refractory bricks are widely used in many industrial fields, and can protect equipment structural parts from high temperature, chemical erosion and wear.
