Method of catalystless denitrification for fluidized bed incinerators

摘要

A method of catalystless denitrification for a fluidized bed incinerator to remove NOx generated in burning refuse such as municipal wastes as the refuse is fluidized in a fluidized bed incinerator is disclosed. The refuse is fluidized together with fluidizing medium such as sand along with primary air, and is thermally decomposed and/or burned. The combustible gases generated by pyrolysis are burned with the secondary air blown into the incinerator in a lattice work arrangement. A denitrification agent is mixed in a part of the secondary air, and the NOx present in the combustion gas is removed without using catalysts.
