Comparison of Circulating Fluidized Bed Boiler and .

The emerging technology of Circulating Fluidized Bed (CFB) combustion is different in many ways from PC combustion. The key differences are listed below. PC firing utilises coal ground to a very fine powder sprayed into the furnace for combustion. CFB uses coal crushed to sizes of around 3 to 6 mm.

Fluidized Bed Combustion System - an overview .

Fluidized Bed Combustion System. Fluidized bed combustion systems are able to reduce SOx by primary measures only down to approximately 150 mg/m3 STP by means of adding dolomite directly into the coal feed where it reacts with the sulfur to form CaSO4 (gypsum), with the result that no further bonding agent is required for the ash product to set when water is added.

Fluidized Bed Boiler - an overview | ScienceDirect Topi

Due to the bed material inside the boiler, fluidized-bed boilers have high heat transfer coefficients, utilize the entire boiler volume, have a uniform temperature distribution and have a low stable combustion temperature. Fluidized beds are capable of burning very wet fuels and fuel particles of sizes up to 80 mm (van Loo and Koppejan, 2006). Thus very little pre-treatment of the fuel is necessary.
