CFB Steam Boiler

Product introduction

Circulating fluidized bed combustion technology is a clean coal combustion technology that developed in the past 20 years, circulating fluidized bed steam boilers have wide fuel adaptation, high combustion efficiency, low NOx emissions, low cost of furnace limestone desulfurization, strong load adaptability, can burn low grade fuels and other advantages. Along with economic development and improvement of the living standard, urban central heating requirements gradually increased, and hot water heating has been developing rapidly in domestic within the past decade.

Circulating fluidized bed boiler data

Circulating fluidized bed boiler application:

Energy saving circulating fluidized bed power plant boiler mainly used for large central heating and urban, enterprises heating system.
Energy-saving circulating fluidized bed boiler work principle:

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. Through fluid state of CFB boiler reconstruction, to reduce auxiliary power and improve availability, while keeping CFB technology advantages of strong coal adaptability and low pollution control cost.

CFB steam boiler advantages:

1, wide fuel adaptation, can not only burn high quality coal but also low quality coal with low volatile and high ash;
2, high combustion efficiency, gas-solid mixing well, large particles unburnt fuel can be recycled back into the furnace burning;
3, high efficient desulfurization, low-temperature combustion and low Nox (nitrogen oxide) emissions.
4, large range of load regulation, load regulation;
5, fuel pre-treatment system simpler compared with pulverized coal fired boiler, is easier to realize comprehensive utilization of ash and slag.
