Biomass Fired CFB Boiler Technology in Europe
15-06-2016
Recently biomass fired CFB boiler technology is spread increase quickly in Europe.CFB boiler technology can also can be called clean coal technology,which can make industrial boiler more efficiently and environment friendly.CFB boiler can burning biomass or coal as fuel to produce steam or hot water whatever you need.
What is CFB Technology in Europe?
CFB technology utilizes the fluidized bed principle in which crushed (6 –12 mm x 0 size) fuel and limestone are injected into the furnace or combustor. The particles are suspended in a stream of upwardly flowing air (60-70% of the total air) which enters the bottom of the furnace through air distribution nozzles.The balance of combustion air is admitted above the bottom of the furnace as secondary air. While combustion takes place at 840-900 C, the fine particles (<450 microns) are elutriated out of the furnace with flue gas velocity of 4-6 m/s. The particles are then collected by the solids separators and circulated back into the furnace. This combustion process is called circulating fluidized bed (CFB). The particles’ circulation provides efficient heat transfer to the furnace walls and longer residence time for carbon and limestone utilization. Similar to PC firing, the controlling parameters in the CFB combustion process are temperature,residence time and turbulence.
Design Features of biomass fired CFB boiler technology in Europe is very comparable to PC-fired boilers in arrangement. The biomass fired CFB boiler technology design consists of the following major systems, The main CFB boiler components are:
• Boiler furnace
• Furnace bottom air distributor and nozzles
• Primary solids separators and recirculation system
• Secondary solids separators and recirculation system
• Pendant superheater / reheater
• Economizer and horizontal tubular air heater
• Air assisted gravity fuel /limestone feed system
Advantages of biomass fired CFB boiler technology in Europe
• Boiler has a smaller foot print (up to 20 to 30% less building volume compared to a hot cyclone-based CFB boiler)
• Boiler design is especially suitable for retrofitting of older PC-fired boilers within the existing support steel.
• Two-stage solids separation efficiency (>99.7%) provides higher carbon efficiencies and better limestone utilization through higher solids residence time.
• Wide turndown ratio (4:1) without auxiliary fuel is possible due to the selection of furnace velocity and controllable solids recycle.
• Less refractory in the boiler allows for quicker start up and lower maintenance costs.
