∙ 12y agoCFBC signifies "Chemical engineering circulating fluid-bed combustion," and is often used in power plants. Fluidized beds suspend solid fuels on vertically blowing jets of air during the combustion process. Boilers that utilize fluid-bed combustion burn fuels at lower temperatures (are more efficient) and can burn fuels other than coal.

What is the difference in Boiler efficiency between CFBC Boiler and PF Boiler while firing powdery coal -50 percent less than 5 mm size?
Cfbc stands for circulating fludised bed combustion where as afbc is for atmospheric fluidise bed combustion afbc bed fluidising velocity is approx 4 m/s and in cfbc boiler fluidising velocity is 9-10 m/s. cfbc having low SOx & NOx comparative with afbc cfbc having higher efficiency up to 98.5 % then afbc boiler,cfbc boiler power consumption is more comparative to afbc.
Cfbc boiler full form?
Circulating fluidised bed combustion
What is the function of cyclone in cfbc boiler?
cyclone is used for to recycle the unburnt and heavy particles into com-buster
How do you calculate coal consumption in afbc boiler?
how we calculate the coal consumed to generate xxx MW say 12 hrs or 24 hrs in CFBC boiler please help
What is PA Fan discharge pressure and bed height maintained in IR CFBC boiler?
1300 mmWc @ full load
CFBC boiler operation procedure?
drum level maintain at48to52% O2 4% id draft _2to+2
When was CFBC created?
CFBC was created on 1946-11-21.
Differences between afbc and cfbc boilers?
(fbc) boiler to heat the Water that is mixed with a refractory material. With warming water temperatures will produce refractory materials that will ignite the oil in the water. The granular refractory materials are mixed with water. Refractory materials are heated in water to take it. c) boiler column. The steam comes out vertically. A) horizontal boiler. The steam comes out horizontally.
Why loop seal provided in cfbc boiler?
loop seal is provided to stop the material from furnace to return leg back.It works with the help of diffrential pressure.There is the difference in the pressure of air beteen furnace and return leg.
What is the meaning of sox and nox in boiler?
SOx ana nox
What is the meaning of once through boiler?
The term "once-through boiler" refers to a special type of water-tube boiler composed oftubes, in which water is input at the bottom, and steam is produced from the top.
Difference between hot cyclone and cold cyclone in cfbc?
Main difference between hot cyclone and cold cyclone is 1. In hot cyclone flue gas temperature is above 800'c., in cold cyclone is is 400 to 500'c. 2. For 3-pass boiler we are used hot cyclone. 3. In reheater system we use hot cyclone to improve the efficiency of boiler.
