BAB I PENDAHULUAN - UMRI

It can be used in high temperature kilns such as blast furnace, boiler, rotary kiln and so on. Wear-resistant and refractory plastics are an important variety of unshaped refractory materials. Refractory plastic is a refractory that cannot be combined with water, and is mainly used in circulating fluidized bed (CFB) boilers.

CFB Boiler Refractory The working principle of CFB boiler is that: low calorific value fuels(coal gangue, inferior anthracite, etc) is crushed and charged into combustion chamber, the fuels is blew into fluidizing state by furnace bottom air blower, then fuel is combusted to supply heat. CFB boiler has strong adaption to different kinds of coals.
