Thermodyne Boilers Manufacture small industrial Boilers more info visit: CFBC uses crushed coal of 3 to 6 mm size. Ash spouts in the furnace remove the ash detaiils the bottom of the furnace.

By continuing to use this website, you agree to their use. This is the Fluidized bed. If You are looking industrial chimney for a boiler, then You will Call Us: This article series explains these issues.

When firing bio fuels with very low ash content sand will be the makeup detils material.

How Circulating Fluidized Bed Boilers Work?

In coal fired boilers the ash from the coal cgbc will be the makeup material. How is it different? This site uses cookies. Circulating Detaios Bed combustion gives the flexibility to burn a wide range of fuels with optimum efficiency and reduced emissions. In the olden days blacksmiths used to heat the iron by placing it on a bed of coal. 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.


The hot gases from the cyclone pass to the heat transfer surfaces and go out of the boiler.

Fluidized Bed At the bottom of the boiler furnace there is a bed of inert material. Special design of the air nozzles at the bottom of the bed allows air flow without clogging.

The coal combustion takes place in this suspended condition. Blog Statshits.

What is CFBC boiler? – Thermodyne Engineering Systems

Notify me of new comments via email. From storage hoppers Conveyer and feeders transport the coal to feed chutes in the furnace. The concentration of ash is dependent of boielr ash mineral matter content and ash mineral matter goes along with flue gases out of the boiler.

Air supply is from under the bed at high pressure. Start up is by oil burners in the furnace. The diagram below shows the schematic of a CFB boiler. Noiler air fans provide the preheated Fluidizing air. Secondary air fans provide pre-heated Combustion air. Bed is where the coal or fuel spreads. Follow me on Twitter My Tweets. 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.

To find out more, including how cfbx control cookies, see here: It adopts a process different from Pulverized Fuel where coal is milled to fine powder similar to talcum powder and fired. The coal is burnt in a bed of hot particles maintained in flowing air. Nozzles in the furnace cbfc at various levels distribute the Combustion air in the furnace.

At the bottom of the boiler furnace there is a bed of inert material. Fill in your details below or click an icon to log in: This bed material is fluidized by primary air a part of combustion air. Hence the name Circulating Fluidized Bed combustion.

The fluidised action promotes complete coal combustion detaips relatively low temperatures, and provides a means to transfer combustion heat efficiently from the bed to the steam tubes. At adequately high air speed, the bed acts as a fluid resulting in rapid mixing of the particles. ddetails

Different boiler manufacturers adopt different methods of cyclone separationthe fluidizing nozzles etc. Email required Address never made public.

Bed Material To start with the bed material is sand. This returns to the furnace for recirculation. This requires only a crusher not a pulverizer.

This lifts the bed material and the coal particles and keeps it in suspension. Some portion is lost in the ash during the operation and this has to be made-up.
