Clinkers resemble volcanic ash and lava. They occur in the high-temperature furnace area of the boiler. Clinkers form as a result of interaction among coal quality, boiler design and boiler operation. Coal boilers draw their combustion air from the bottom, up through the combustion grate.

It is reported that circulating fluidized bed boilers are more an more appeared in industries and commercial fields. Someone consult for AFBC boiler, while some search for CFBC boiler. And they are usually confused: are the two the same or what's the difference between AFBC and CFBC?

CFBC boiler - cold cyclone design Advantages of Cold Cyclone CFBC Boiler over Bubbling Bed Boiler Advantages of Cold Cyclone CFBC Boiler over Pulverised Fuel Boiler 1 Thermal Efficiency ~87% ~87% Practically Same 2. Power consumption Higher due to grinding Lower than PF No milling equipment 3.

Boiler with circulating fluidized bed CFBC Boiler. 20171215The features of circulating fluidized bed boilers are described below 1 Compatibility with wide range of fuels Conventional boilers for power generation can use only fossil fuels, such as highgrade coal, oil, and gas The CFBC is also capable of using lowgrade coal, biomass, sludge, waste plastics, and waste

Circulating Fluidized Bed (CFB) combustion boilers gives the flexibility for combustion of a wide range of coals and alternative fuel sources. All this without compromising efficiency and with reduced emissions. This article gives a brief description of the working of a CFB boiler. At the bottom of the boiler furnace there is a bed of inert material.

Fluidized Bed Combustion. Atmospheric fluidized beds use limestone or dolomite to capture sulfur released by the combustion of coal. Jets of air suspend the mixture of sorbent and burning coal during combustion, converting the mixture into a suspension of red-hot particles that flow like a fluid. These boilers operate at atmospheric pressure.

Dec 12, 2012· 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 .

Jan 15, 2019· Pulverized coal-fired Boiler or Pulverized fuel Boiler. A pulverized coal-fired boiler is an industrial boiler that generates thermal energy by burning pulverized coal. How does a steam boiler work? In pulverized coal fired boiler,The coal is pulverized to a fine powder, so that less than 2 % is +300 micro meter and 70 – 75 % is below 75 microns.
