Why High-Purity Corundum Bricks Are Used For The Hot Bricks Of Heavy Oil Gasifiers

Heavy oil gasifiers are equipment that converts heavy petroleum products (such as heavy oil, residual oil, tar, etc.) into synthesis gas (mainly carbon monoxide and hydrogen) through a high-temperature and pressure gasification process. The reason why high-purity corundum bricks are used for their hot bricks is mainly because their working environment is relatively harsh, and it is often in a high-temperature, high-pressure, corrosive, and wear-resistant working environment. To withstand such a working environment, it is necessary to select high-temperature, corrosion-resistant, and wear-resistant refractory materials.

High-purity corundum bricks are high-quality refractory bricks. Its alumina content can reach more than 90%, with excellent high-temperature resistance, and the refractory temperature can reach more than 1800℃. At the same time, it has a high room temperature compressive strength, and the compressive strength can reach more than 100Mpa, which can withstand the high-pressure environment of heavy oil gasifiers. High-purity corundum bricks have a very high load softening start temperature, which can ensure the stability of the heavy oil gasifier. In addition, high-purity corundum bricks also have good corrosion resistance and wear resistance. These characteristics are essential conditions for ensuring the normal operation of the heavy oil gasifier.

The selection and arrangement of hot face bricks of the heavy oil gasifier are very important for the gasifier. Reasonable selection of refractory materials can ensure the uniform distribution of heat inside the gasifier, and at the same time resist gas scouring and corrosion, ensuring the stability of the working environment of the kiln. In addition, the arrangement of hot face bricks also needs to consider factors such as fluid dynamics and the combustion process in the furnace to ensure the durability and safety of related components.
