Special design of the air nozzles at the bottom of the bed allows air flow without clogging. You are commenting using your WordPress. 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.
How Circulating Fluidized Bed Boilers Work?
Menu Skip to content About Contact. Email required Address never made public. Thermodyne Boilers Manufacture small industrial Boilers more info visit: How is it different? Bed is where the coal or fuel spreads.
Fluidized Bed combustion is something similar to this. CFBC uses crushed coal of 3 goiler 6 mm size. The coal is burnt in a bed of hot particles maintained in flowing air.
Secondary air fans provide pre-heated Combustion air. Primary air fans provide the preheated Fluidizing air. Do not waste Energy on steam leakage in boiler.
This lifts the bed material and the coal particles and defails it in suspension. Some portion is lost in the ash during the operation and this has to be made-up. This is one way of burning pulverised coal in electricity generation plant.
Bed Material To start with the bed material is sand. Start up is by oil burners in the furnace. Different boiler manufacturers adopt different methods of cyclone separationthe fluidizing nozzles etc.
To start with the bed material is sand. To find out more, including how to control cookies, see here: How does this technology work?
This bed material is fluidized by primary air a part of combustion air. In coal fired cfbf the ash from the coal itself will be the makeup material.
From storage hoppers Conveyer and feeders transport the coal to feed chutes in the furnace.
Hence the name Circulating Fluidized Bed combustion. Detaile are commenting using your Twitter account. But the basic principles remain the same.
What is CFBC boiler? – Thermodyne Engineering Systems
Author archive Author website. 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. Fill in your details below or click an icon to log in: Blog Statshits.
When firing bio fuels with very low ash content sand will be the makeup bed material. In the olden days blacksmiths used to heat the iron by placing it on a bed of coal. This article series explains these issues. Circulating Fluidized Bed combustion gives the flexibility to burn a wide range of fuels with optimum efficiency and reduced emissions.
Follow me on Twitter My Tweets. 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. This is the Fluidized bed.
At the bottom of the boiler furnace there is a bed of inert material. This requires only a crusher not a pulverizer. You are commenting using your Facebook account.
The hot gases from the cyclone pass to the heat transfer surfaces and go out of the boiler. What are the advantages? Nozzles in the furnace walls at various levels distribute the Combustion air in the furnace.
