Abstract

The invention discloses a chain-grate spraying and denitrifying corner tube boiler with a horizontal single boiler barrel. The chain-grate spraying and denitrifying corner tube boiler with the horizontal single boiler barrel structurally comprises a boiler body, a cyclone separator, a U-shaped return feeder, a treatment area and an exhaust pipe, wherein the boiler body is connected with the cyclone separator through a convection pass; 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 a discharge flue; the cyclone separator comprises the convection pass, a denitrifying agent nozzle and the discharge flue; the convection pass is connected with a hearth; the denitrifying agent nozzle and the convection pass are connected through a bolt; the discharge flue is connected with the cyclone separator; the U-shaped return feeder comprises the return flue, a return fan and a loosening fan; and thetreatment area comprises an overheater, an economizer and a soot blower. A reducing agent and a flue gas are reacted for the sufficient reaction time, so that the accidents of return termination andboiler coking are avoided, and the chain-grate spraying and denitrifying corner tube boiler with the horizontal single boiler barrel is high in efficiency and saves energy.

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...
