Understanding of the mechanisms of the combustion of char and volatiles with regard to their contribution to the levels of NO(x) and N(2)O formed in both atmospheric and pressurized fluidized bed combustorsFunded under: ECSC-COALRES 7C
The purpose of this project was to understand better the complexity of the interaction between reactions and fluid dynamics occurring in various types of fluidized bed combustors during the combustion of coals with the aim of minimizing the levels of NO(x) and N(2)O formed. Studies were undertaken with regard to the formation of N(2)O and NO(x) during fluidized bed combustion of coals. The nature of nitrogenous compounds present in parent coal and the temperature of devolatilization have an important influence on the amount of both N(2)O and NO formed. The main source of both N(2)O and NO is the combustion of char; however, the volatiles significantly contribute to the amount of N(2)O formed. Char also appears to give rise to a considerable reduction of both N(2)O and NO during combustion.
