The coal is burnt in a bed of hot particles maintained in flowing air. This returns to the furnace for recirculation. Some portion is lost in the ash during the operation and this has to be made-up.
Email required Address never made public. This lifts the bed material and the coal particles and keeps it in suspension. 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.

Menu Skip to content About Contact. Hence the name Circulating Fluidized Bed combustion. This bed material is fluidized by primary air a part of combustion air. The hot gases from the cyclone pass to the heat transfer surfaces detailw go out of the boiler. Fine particles of partly burned coal, ash and bed material are carried along with the flue gases to the upper detials of the furnace and then into a cyclone.
What is CFBC boiler? – Thermodyne Engineering Systems
Special design of the air nozzles at the bottom of the bed allows air flow without clogging. Ash spouts in the furnace remove the ash from the bottom of the furnace.
Blog Statshits. In coal fired boilers the ash from the coal ddetails will be the makeup material.
To find out more, including how to control cookies, see here: Secondary air fans provide pre-heated Combustion air. For high Sulphur coals Limestone addition to the bed material reduces SO 2 emissions.
Follow me on Twitter My Tweets. The coal combustion takes place in this suspended condition. At the bottom of the boiler furnace there is a bed of inert material.
How Circulating Fluidized Bed Boilers Work?
Primary air fans provide the preheated Fluidizing air. This is one way of burning pulverised coal in electricity generation plant. You are commenting using your Twitter account. To start with the bed material is sand.
But the basic principles remain the same. This requires only a crusher not a pulverizer. The diagram below shows the schematic of a CFB boiler.
Bellows provide air to the coal from the bottom of the bed. Nozzles in the furnace walls at various levels distribute the Combustion air in the furnace.
From storage hoppers Conveyer and feeders transport the coal to feed chutes in cfbf furnace. How is it different? CFBC uses crushed coal of 3 to 6 mm size. Fluidized Bed combustion is something similar to this.
Do not waste Energy on steam leakage in boiler. What are the advantages?
If You are looking industrial chimney for a boiler, then You will Call Us: This is the Fluidized bed. It adopts a process different from Pulverized Fuel bioler coal is milled to fine powder similar to talcum powder and fired.
