Heat recovery boiler(Waste heat boiler)

 

Working Condition Analysis
The core equipment for pre-decomposition. The calcination furnace undertakes the decomposi-tion of carbonate which consumes the most heat during clinker calcination, thus increasing thedecomposition rate of raw material. The decomposition rate of raw materials in the decompos-ing furnace is usually 85%-95%, By supplying air three times to achieve graded combustion, theemission of nitrogen oxides is effectively reduced.The temperature in the calciner fluctuatesgreatly. lts easy to crust in the calciner, A large amount of coal is burned in a calciner and alter-native fuels are added in the same time.

 

Refractory Material Requirements
SiC and zirconia need to be added to increase wear resistance
High thermal vibration performance
Anti-crusting

Products

High Strength Alkali Resistance Brick

High-strength alkali-resistant brick is generally a refractory brick made on the basis of low aluminum clay bricks with Al2O3 content of 25 to 30%, adding silica, coke gems and appropriate additives to improve the compressive strength.
