Wholesale Price Industrial Food Use Coal Fuel CFB products description
1. Energy saving circulating fluidized bed power plant boiler mainly used for large central heating, thermal power plants to generate electricity or other purposes.
2. Energy-saving circulating fluidized bed power plant boiler as one of the circulating fluidized bed boilers, it utilizes stationary design theory and CFB technology spectrum, to optimize and decrease the total stock of CFB with the Theory of Material Balance and Large Particle Combustion Theory, thus forms energy saving circulating fluidized bed technology based on the reconstruction of fluid state. Performance
Advantage
1. High burning efficiency, good gas and coal particle mixing,the unburned big particles can be recycled to the hearth and be reused efficiently.
2. De-sulfur efficiency is high,and the burning temperature is low,so,the NOX emission is low.
3. The load can be adjusted in a wide range and with a high speed.
4. The pretreatment system is simple(comparing to the coal powder boiler),the coal residue can be synthetically used.
