What is the difference between an AFBC and CFBC boiler ...
AFBC is atmospheric fluidised bed combustion, where the furnace pressure is atmospheric pressure. The flue gas from the furnace goes through a cyclone and is let out to the atmosphere. In case of CFBC, Circulating fluidised bed combustion, the furnace is pressurised and the furnace gas is recirculated...
AFBC Boiler VS CFBC Boiler - circulatingfluidizedbedboiler.com
Advantages of CFBC Boiler over AFBC Boiler. CFBC technology evolves from AFBC to overcome some of the Problems of AFBC. a).Better Space utilization for large Industrial units b).Efficient combustion c).Better SO2 capture d). Better Techniques for Nox Control e).Better temperature Control
What is the Difference Between AFBC and CFBC Boiler
What is the Difference Between AFBC and CFBC Boiler. Better for low garde Fuel with Low calorific value and high Ash content h). Reduced Erosion of heat transfer surface in combustion chamber as surface is parallel to the flow contrary to AFBC Zhengzhou Boiler Group (ZBG) is a leading boiler manufacturer, supplier and exporter in China.
Presentation on CFBC Boilers - SlideShare
Presentation on CFBC Boilers. 4. CFBC BOILER As the air increased further , the bed become less uniform bubbles of air start to form and the bed becomes violent . At this condition bed is in expanded condition, This is called bubbling fluidized bed and this occurs at atmospheric condition.
Difference Between AFBC And CFBC Boilers--ZBG
Difference Between AFBC And CFBC Boilers. CFBC boiler stands for circulating fluidized bed combustion boiler, the furnace is pressurised and the furnace gas is recirculated to capture the unburnt carbon, to increase the thermal efficiency of the boiler. Hence this is an improved version of AFBC.
