Abstract

The invention discloses a single-drum transverse chain grate spraying denitration corner tube boiler. The boiler structurally comprises a boiler body, a cyclone separator, a U-shaped return feeder, atreatment area and an exhaust pipe, wherein the boiler body is connected with the cyclone separator through a convection flue; the U-shaped return feeder is connected with the boiler body through a return flue; the treatment area is connected with the cyclone separator through an outlet flue; the cyclone separator comprises the convection flue, a denitration agent nozzle and the outlet flue; the convection flue is connected with a hearth, the denitration agent nozzle is connected with the convection flue through a bolt; the outlet flue is connected with the cyclone separator; the U-shaped return feeder comprises the return flue, a return fan and a loosening fan; and the treatment area comprises a superheater, a coal economizer and an ash blower. A reducing agent and flue gas have sufficient reaction time, the boiler coking accident caused by return stop is avoided, and high efficiency and energy conservation are achieved.

Description

technical field [0001] The invention relates to a single-drum horizontal chain grate spraying denitrification corner tube boiler, which belongs to the field of flue gas denitrification equipment. Background technique [0002] Nitrogen oxide (NOx) is a gas produced by the oxidation of nitrogen during the combustion process. It not only stimulates the human respiratory system, damages animals and plants, and destroys the ozone layer, but is also one of the main substances that cause the greenhouse effect, acid rain, and photochemical reactions. First, the boiler denitrification equipment is the equipment that removes nitrogen oxides in the combustion flue gas. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a single-drum horizontal chain grate spray denitrification angle tube boiler to solve the problem of effectively controlling the generation and emission of NOx during the combustion proces...
