Limestone-based desulfurizing agent of fluidized bed boiler

2A3. Internal Circulating Fluidized-bed Combustion Technology …

For the fluidized-bed boiler, desulfurization takes place mainly in the furnace. However, ICFBC does not have a heat transfer tube in the fluidizing section, so the boiler does not cause wear on the heat transfer tube in the bed. Because of this, silica sand can be

CFBC Boiler vs Pulverized Fired Boiler - SlideShare

2015/12/11 · The classical CFBC Boiler operates at the higher end of the fluidized bed regime, just lower than the transport phase. It includes a fluid bed expanded all the way to the roof of the combustor instead of restricting the bed to the lower part as in a BFBC boiler. 13.

NO Emissions from Anthracite Oxy-Firing in a Fluidized-Bed Combustor: Effect of the Temperature, Limestone…

2020/11/7 · Along with SO2, NOx emissions are considered the main pollutants from solid-fired combustion systems. In fluidized-bed boilers, injection of limestone pursues SO2 retention, achieving capture efficiencies over 90%. Nevertheless, CaO formed from limestone calcination has been identified as a catalyst of N-compound reactions, increasing NO emissions. This paper investigates the effect of
