Valmet CFB Boiler utilizes circulating fluidized bed

Valmet CFB Boiler (formerly known as CYMIC) is an advanced circulating fluidized bed (CFB) boiler developed by Valmet. It combines high-efficiency combustion of various solid fuels with low emissions, even when burning fuels with completely different calorific values at the same time.

Flue-gas stack - Wikipedia

A flue-gas stack, also known as a smoke stack, chimney stack or simply as a stack, is a type of chimney, a vertical pipe, channel or similar structure through which combustion product gases called flue gases are exhausted to the outside air. Flue gases are produced when coal, oil, natural gas, wood or any other fuel is combusted in an industrial furnace, a power plant's steam-generating boiler

Nicholas P. Cheremisinoff, in Clean Electricity Through Advanced Coal Technologies, 2012 2.5 Flue-Gas Desulfurization Material. Flue-gas desulfurization (FGD) material is a product of a process typically used for reducing SO 2 emissions from the exhaust gas system of a coal-fired boiler. The physical nature of these materials varies from a wet sludge to a dry, powdered material depending on

Boiler Combustion | CleanBoiler.org

Flue gas desulfurization involves the utilization of scrubbers to remove SOx emissions from the flue gases. Flue gas desulfurization systems are classified as either non-regenerable or regenerable. Non-regenerable FGD systems, the most common type, result in

Flue Gas - an overview | ScienceDirect Topics

The flue gas enters the lower part of the desulfurization absorption column under the action of the booster fan after being dusted by the dust collector. In the rising process, it comes into full contact with the falling limestone slurry sprayed by the spray. SO 2 in the flue gas is absorbed by the slurry and falls into the slurry pool at the bottom of the column.

While the flue gas desulfurization equipment in conventional coal-fired thermal power generation required a large amount of water for treating flue gas after fuel operation, IGCC consumes a much smaller amount of water because it treats fuel gas that is higher in pressure and smaller in volume.
