Refractory Materials for Biofuel Boilers | IntechOpen

Like a sandblaster, these products will wear away at the refractory lining over time. Thermal cycling: Boilers and furnaces cycle in their heat production, generating massive amounts of heat up to 3,000°F before cooling off. Refractory linings, therefore, undergo the same thermal cycling, causing the refractory materials to expand and contract

Refractory material for circulating fluidized bed boiler

Dec 27, 2018 · For boilers and heaters that use biomass as fuel, the impurities can have a negative effect on refractory lining. During service, corrosive compounds can accumulate from biomass combustion, resulting in slag formation. Slag is created from ash residue of the combusted biomass. Biomass ash is composed of oxides such as silica (SiO2) and alumina
