Oxidation of Volatile Nitrogen Compounds during Combustion in Circulating Fluidized Bed Boilers

Artikel i vetenskaplig tidskrift, 1991

In circulating fluidized bed boilers, the volatile nitrogen species of the fuel are mostly oxidized to NO. This is shown in a test program where the effect of batch supply of fuel on the NO emission has been investigated in two different commercial-type fluidized bed boilers. Measurements of gas concentration profiles of CO, NO, HCN, NH3, and C1 to C3 hydrocarbons in the boilers support the conclusions from the batch supply tests.
