How to Choose Flue Refractory Bricks

The flue is a tubular device for emitting waste gas and smoke. It is an essential part of a high-temperature kiln. Since the temperature of a high-temperature kiln is relatively high, the temperature of the flue gas produced can reach thousands of degrees. To ensure that the flue is normal for the operation and service life of the flue, the flue refractory bricks used in the process of building the flue are very important. They must have good heat resistance and chemical resistance.

The selection of flue refractory bricks is generally based on lightweight refractory bricks, which can withstand high temperatures and reduce the weight of the flue, thus ensuring the normal operation of the flue. Generally, lightweight refractory bricks are mainly divided into light-quality mullite refractory bricks, lightweight clay refractory bricks, and lightweight silica bricks should be selected according to the properties of the flue gas produced by the medium, such as the temperature of the flue gas, whether the flue gas is corrosive, etc., so that Only in this way can we choose the right refractory bricks correctly.

When purchasing refractory bricks for flues, we need to consider several factors. The first is the type and specification of bricks. Common flue refractory bricks include full-shaped bricks, half-shaped bricks top hole bricks, etc., and there are various sizes to choose from. The second is the heat resistance and corrosion resistance of bricks. We need to choose suitable brick materials according to the specific use environment and process requirements. In addition, factors such as brick prices and supply channels also need to be considered.

The selection of flue refractory bricks is also very important in high-temperature kilns. It also affects the service life of high-temperature kilns to a certain extent. If the flue is damaged prematurely, it will be difficult to use the high-temperature kiln as a whole. Failure to discharge the gas is also very dangerous for high-temperature kilns. Once the flue gas is excessive, there is a high risk of explosion, so the flue is very important for high-temperature kilns.
