Air supply is from under the bed at high pressure. But the basic principles remain the same. How does this technology work?

CFBC uses crushed coal of 3 to 6 mm size. Start up is by oil burners in the furnace.

This is the Fluidized bed. Hence the name Circulating Fluidized Bed combustion. This site uses cookies. 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.

Thermodyne Boilers Manufacture small industrial Boilers more info visit: Some portion is lost in the ash during the operation and this has to be made-up. In coal fired boilers the ash from the coal itself will be the makeup material. To start with the bed material is sand. The coal combustion takes place in detaails suspended condition. 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.

Fluidized Bed At the bottom of the boiler furnace there is a bed of inert material.

How Circulating Fluidized Bed Boilers Work?

This returns to the furnace for recirculation. Nozzles in the furnace walls at various levels distribute the Combustion air in the furnace. Ash spouts in the furnace remove the ash from the bottom of the furnace. How is it different? From storage hoppers Conveyer and feeders transport the coal to feed noiler in the furnace. At the bottom of the boiler furnace there is a bed of inert material.
