Jan 19, 2015 · PC (Pulverised Coal) Boiler. Coal is combusted at temperatures of about 1600-1800 deg C. At such high temperatures, NOx, which is a notorious pollutant, is formed. SOx pollutants are carried away in flue gases, which condense to form highly corrosive sulphuric acid at temperatures around 140-160 deg C.

This bed material is fluidized by primary air (a part of combustion air) The high concentration
IEA Clean Coal Centre– Operating experience of low grade fuels in circulating fluidised bed combustion (CFBC) boilers 4. Abstract. Although subject to sometimes quite considerable short-term variations, the long term trend for the price of coal, along with other primary energy resources, is upwards.
CFBC boilers are mostly claimed to be more cost effective than AFBC boilers for industrial uses requiring more than 80-110 T/hr of steam. CFBC needs huge mechanical cyclones to aquire and recycle the high amount of bed material, which need tall boiler. Fig. shows CFBC bed boiler.
In the olden days blacksmiths used to heat the iron by placing it on a bed of coal. Bellows provide air to the coal from the bottom of the bed. Fluidized Bed combustion is something similar to this. Fluidized Bed. At the bottom of the boiler furnace there is a bed of inert material. Bed is where the coal or fuel spreads.
Pressurized fluidized bed combustion (PFBC) For hard coal applications, the coal and limestone can be crushed together, and then fed as a paste, with 25% water. As with atmospheric FBC (CFBC or BFBC), the combustion temperature between 800-900°C has the advantage that NOx formation is less than in PCC, but N2O is higher.
