Selection of Bricks for the Regenerator of Hot Blast Stove

As a Refractory Material Supplier, share it with you.

The regenerator of the hot blast stove is a space filled with silica bricks for the hot blast stove. The main function is to use the internal silica bricks for the hot blast stove to exchange heat with high-temperature flue gas and combustion air.

Silica Brick for Hot Blast Stove

Therefore, as the heat storage and heat transfer medium, the silica bricks for hot blast stoves should have a larger heating area, higher thermal conductivity and quality to facilitate heat exchange and heat storage; and the method of increasing the heating area is mainly in The number of holes of silica bricks for hot blast stoves increases per unit area, so the number of holes for silica bricks for hot blast stoves in regenerators tends to increase.

In order to improve the thermal conductivity of the material, black silica bricks are commonly used in Europe for hot blast stove silica bricks inside the regenerator, because black silica bricks contain high iron oxide content, high density, high thermal conductivity, and heat storage capacity. Strong, high heat exchange efficiency.

Therefore, the upper part of the regenerator adopts siliceous checker bricks, the middle part of the regenerator adopts low-creep high-alumina bricks, mullite bricks, sillimanite, andalusite bricks, etc., and the lower part of the regenerator generally adopts clay bricks.
