Abstract
PURPOSE:To mix securely and evenly a denitration agent into gas and denitrate efficiently without disordening the arrangement of primary function of a boiler by dispersing and injecting a denitration agent into an air current in a stack of a cyclone. CONSTITUTION:A combustor 1 with a dense bed 9 is communicated with a cyclone 4 which is communicated with the combustor 1 and also communicated with an outside heat exchanger 2 at its lower section and an outside heat exchanger 2. A denitration agent K is dispersed and injected from an injection tube 31 into the air current in a stack 45 of the cyclone 4 of a circulating type fluidized boiler through branch pipes 32a, 32b and 33 and a ring tube 34 and also nozzles 35-37. As a result, the nitration agent can be mixed evenly into gas without disordering the primary function of control of the boiler to carry out an efficient denitration.
