Low polluting NOx and SOx emissions are significantly decreased without special environmental modifications. In the case of fluidized-bed boilers, desulfurization is carried out intrafurnace, using mainly limestone as the fluidizing material. For denitration, PC boilers operate at combustion temperatures from 1,400oC to 1,500oC, whereas circulating fluidized-bed boilers operate at …
