Waste incinerators are the main equipment for treating municipal solid waste, but their operating environment is extremely harsh. Therefore, the selection of furnace lining materials is crucial, and the suitability of refractory bricks directly affects the safety and lifespan of the equipment.
1. Core Challenges of Incinerator Lining
The lining of waste incinerators faces multiple severe challenges. First, the temperature inside the furnace is usually above 1000℃. This requires refractory materials to have excellent high-temperature resistance.
Secondly, the composition of waste is complex and varied. The alkali metals, salts, and acidic gases produced during combustion can cause severe chemical corrosion to refractory materials.

In addition, the incinerator operates intermittently, and its waste feeding is uneven. This can also cause temperature fluctuations inside the furnace, resulting in thermal shock and thus accelerating material fatigue and damage.
Under the combined effect of these factors, ordinary refractory bricks often peel off, thin, or even fail within a few months. Therefore, it is essential to select refractory materials with strong erosion resistance and good thermal shock stability.
2. Choosing the right refractory bricks is key
To effectively address these challenges, selecting high-quality refractory bricks is key to solving the problem.
For example, in areas where corrosion and wear are most severe, such as the combustion chamber and grate. High-performance products such as chrome corundum bricks or silicon carbide bricks are usually required.This is because these types of refractory bricks not only have a dense structure and high strength, but also excellent resistance to chemical erosion and thermal shock.
In contrast, ordinary clay bricks or high-alumina bricks would deteriorate rapidly in such extreme environments, leading to frequent furnace shutdowns for maintenance, which would significantly increase overall costs.

Therefore, in the long run, selecting high-performance refractory materials is a wise move to ensure the continuous operation of equipment.
3. Comprehensive considerations: From refractory brick manufacturers to refractory brick prices
After determining the required refractory brick type, choosing the right refractory brick manufacturer and supplier is equally important.
A professional manufacturer can not only provide products that meet standards, but also offer customized solutions and technical support based on specific kiln conditions.
When evaluating the price of refractory bricks, one should not only look at the unit price of purchase, but also consider the overall cost.
