Cover the water-cooled wall around the combustion chamber with refractory materials to increase the temperature in the combustion area. Almost all combustion chambers in domestic thermal power plants use ordinary plastic materials, commonly known as castables. Although this type of castable is cheaper in price, it is prone to detachment, foaming, bursting, and has a poor heat transfer coefficient. If using blue mud technology for construction, it has thin walls, strong adhesion, no foaming, no bursting, and can extend the service life of two major maintenance periods, and the thermal conductivity is also very good.
