Circulating Fluidized Bed Biomass Boiler (Island)
Circulating Fluidized Bed (CFB) is a relative new technology with the ability to achieve lower emission of pollutants. Extensive research has been conducted on this technology for the past 10 years because pollution in the world is getting more serious by the day and clean practice will be very crucial for the sustainability of the earth. The importance of this technology grew even more lately because of the tightened environmental regulation for pollutant emission.
Circulating Fluidized Bed is a good choice to burn Liquid Biomass, Low LHV Biomass and Small Size Biomass.
Liquid Biomass
The Liquid Biomass normally is a kind of liquid that contains biomass suspended matter. It normally comes from industrial or chemical procedure. There are two way to burn this fuel.
- Dry it and burn
- Spray it into furnace
By any kind of drying, some volatile matter will gone, LHV goes down. Those fuels contain low volatile matter will fit this way. The dried biomass can be used as fuel of Combined Grates boiler.
Using CFB boiler and a series of nozzle to spray it into boiler is an easy way.
Low LHV Biomass
Low LHV (Lower Heating Value) Biomass is a kind of wastes that from producing other biomass product. Like Wood Bark, Furfural Residue, etc. Some are very wet, high moisture brings LHV down.
This kind of biomass is difficult to ignite, difficult to burning smoothly.
CFB boiler provides a steady furnace temperature. New fuel enters boiler, ignited by exist fuel, burn and release more heat, keeps the furnace temperature.
