coal fired biomass steam boiler
Box Group in their own development, bearing in mind the social responsibility, personally, set an example, to carry forward traditional Chinese virtues. We hope that through this way, to get more attention of the community. We work together to build a healthy growth of childhood for the children, to give them a future full of faith!
How does the CFB boiler work
CFB technology burns fuels without fire or burners in the furnace but through a process of fluidization mixes the fuel particles with limestone which captures the sulfur oxides that are formed and the low temperature reduces nitrogen oxide formation. The limestone and fuel are recycles multiples times which increases both the efficiency of producing high quality steam to produce power and also reduces pollution due to its ability to burn fuel in a clean way than the conventional processes. Circulating fluidized bed technology(CFB) also offers the flexibility of using both coal as well as biomass fuels.
Each boiler will generate 250 tons/hour of low-pressure steam for the alumina refinery; however, the design allows for conversion to high-pressure steam generation for the future addition of a steam turbine for electricity generation.Coal or biomass will be the primary and backup fuels, respectively.
Dual bagasse and coal feeder for coal fired biomass steam boiler not only can burn bagasse but also can burn coals. With the development of the economy, people begin to seek for a new lifestyle, and environment protection becomes a hot issue. Biomass fired steam boiler becomes more and more popular owing to its high efficiency, low combustion, little pollution and environment protection. Bassage is one type of biomass energy and many places use the bagasse as the fuel to heat the biomass fired steam boiler and some places use both the bagasse and the coals as the fuels to steam boiler. Both of these two types are becoming more and more popular.
