Fluidized Bed combustion is something similar to this.

How Circulating Fluidized Bed Boilers Work?

This returns to the furnace for recirculation. How does this technology work?

Start up is by oil burners in the furnace. Menu Skip to content About Contact. But the basic principles remain the detaild. How is it different? Blog Statshits. Ash spouts in the furnace remove the ash from the bottom of the furnace. Circulating Fluidized Bed combustion gives the flexibility to burn a wide range of fuels with optimum efficiency and reduced emissions.

CFBC uses crushed coal of 3 to 6 mm size. This is one way of burning pulverised coal in bojler generation plant. 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.

Nozzles in the furnace walls at various levels distribute the Combustion air in the furnace.

Special design of the air nozzles at the bottom of the bed allows air flow without clogging. Bellows provide air to the coal from the bottom of the bed.

To start with the bed material is sand. Bed is where the coal or fuel spreads. In coal fired boilers the ash from the coal itself will be the makeup material. You are commenting using your Twitter account. Author archive Author website. Do not waste Energy on steam leakage in boiler.

ISGEC | CFBC Boilers | Circulating Fluidised Bed Combustion Boilers

The coal is burnt in a bed of hot particles maintained in flowing air. The coal combustion takes place in this 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. Primary air fans provide the preheated Fluidizing air.

How Circulating Fluidized Bed Boilers Work?

At adequately high air speed, the bed acts as a fluid bpiler in rapid mixing of the particles. Notify me of new comments via email. In the cyclone the heavier particles separate from the gas and falls to the hopper of the cyclone. Email required Address never made public.

The fluidised action promotes goiler coal combustion at relatively low temperatures, and provides a means to transfer combustion heat efficiently from the bed to the steam tubes. To find out more, including how to control cookies, see here: From storage hoppers Conveyer and feeders transport the coal to feed chutes in the furnace.

What are the advantages? Some portion is lost in the ash during the operation and this has to be made-up.
