In the input part of the incinerator, since the input and fall of the waste need to be in contact with the material, and the temperature of the input port often changes, the refractory is required to have good wear resistance and thermal shock resistance. Clay bricks can be used. In the drying chamber and combustion chamber, the waste and the furnace lining are in direct contact at high temperatures. On the one hand, the slag will adhere to the furnace lining, and on the other hand, impurities will also pour into the furnace lining. At the same time, the input of waste will inevitably cause temperature changes, so refractory is required The material is not only wear-resistant, corrosion-resistant, difficult to adhere, but also resistant to alkali and oxidation,
Generally use clay bricks, high alumina bricks, silicon carbide bricks, SIC bricks, castables and plastics.
In pipelines and gas cooling parts, due to water spray, impurity intrusion and temperature changes, refractory materials are required to be resistant to alkali and water, thermal shock resistance, optional castables, in the fluidized bed part of the mobile incinerator, during the mixing process of high temperature boiling sand and waste.
Not only scouring the furnace lining, but also impurities poured in, so the selected furnace lining should be wear-resistant and alkali-resistant, and clay bricks and castables are commonly used.In the rotary kiln part of the rotary kiln-type incinerator, the waste needs to rotate continuously and the addition of the waste causes the temperature change. Therefore, the material is required to be wear-resistant and thermal shock resistance. Generally, clay bricks,
high alumina bricks, and
silicon carbide bricks are used. , Or castable, refractory materials for garbage incinerators are roughly divided into refractory bricks and unshaped materials. The former includes clay bricks, high alumina bricks, and silicon carbide bricks. The latter is made of clay, high alumina, and silicon carbide castables, clay, high-aluminum and plastic-based.
