The diagram below shows the schematic of a CFB boiler. The coal combustion takes place in this suspended condition. What are the advantages?
Bellows provide air to the coal from the bottom of the bed. Follow me on Twitter My Tweets. Fluidized Bed combustion is something similar boilfr this. Leave a Reply Cancel reply Enter your comment here This lifts the bed material and the coal particles and keeps it in suspension. The concentration of ash is dependent of coal ash mineral matter content and ash mineral matter goes along with flue gases out of the boiler.
Notify me of new comments via email. The hot gases from the cyclone pass to the heat transfer surfaces and go out of the boiler. Circulation Fine particles of partly burned coal, ash and bed material are carried along with the flue gases to the upper areas of the furnace and then into a cyclone. This bed material is fluidized by primary detzils a part of combustion air.
In the olden days blacksmiths used setails heat the iron by placing it on a bed of coal. Hence the name Circulating Fluidized Bed combustion.
Nozzles in the furnace walls at various levels distribute the Combustion air in the furnace. Fill in your details below or click an icon to log in: Email required Address never made public.

Do not waste Energy on steam leakage in boiler. Thermodyne Boilers Manufacture small industrial Boilers more info visit: This article series explains these issues. But the basic principles remain the same. Start up is by oil burners in the furnace. This is the Fluidized bed.
Bed Material To start with the bed material is sand. Some portion is lost in the ash during the operation and this has to be made-up. By continuing to use this website, you agree to their use. In coal fired boilers the ash from the coal itself will be the makeup material. This requires only a crusher not a pulverizer.
Fine particles of partly detals coal, ash and bed material are carried along with the defails gases to the upper areas of the furnace and then into a cyclone. For high Sulphur coals Limestone addition to the bed material reduces SO 2 emissions. You are commenting using your WordPress.
Bed is where the coal or fuel spreads. This is one way of burning pulverised coal in electricity generation plant.
Fluidized Bed At the bottom of the boiler furnace there is a bed of inert material. You are commenting using your Twitter account.
Blog Statshits. When firing bio fuels detauls very low ash content sand will be the makeup bed material. The fluidised action promotes complete coal combustion at relatively low temperatures, and provides a means to transfer combustion heat efficiently from the bed to the steam tubes.
