Low-nitrogen combustion device of gas-fired boiler

Abstract

The invention discloses a low-nitrogen combustion device of a gas-fired boiler. The low-nitrogen combustion device comprises a box body, a gas buffer chamber and an air buffer chamber are formed in the box body, and first supporting rods are connected between the two sides of the gas buffer chamber and the inner walls of the two sides of the box body correspondingly; second supporting rods are connected between the two sides of the air buffer chamber and the inner walls of the two sides of the box body correspondingly; the gas buffer chamber communicates with a first gas pipe and a second gaspipe, the first gas pipe is connected with a first flow division pipe, and the second gas pipe is connected with a second flow division pipe; the air buffer chamber communicates with a first air pipeand a second air pipe, the first air pipe is connected with a third flow division pipe, and the second air pipe is connected with a fourth flow division pipe; and a mixing tank is further arranged inthe box body. The low-nitrogen combustion device has the characteristics that sufficient combustion is convenient, and generation of nitric oxides is reduced advantageously.

Description

technical field [0001] The invention relates to the technical field of gas boilers, in particular to a low-nitrogen combustion device for gas boilers. Background technique [0002] Gas-fired boilers, as the name implies, refer to boilers whose fuel is gas. During the combustion process, some nitrogen oxides will be produced, and the discharge of nitrogen oxides into the atmosphere will cause serious environmental pollution. Nitrogen oxides will dissolve in rainwater and form nitric acid. rain. Therefore, when the gas boiler is burning, it is necessary to reduce the production of nitrogen oxides. [0003] However, when the existing equipment is burned, the gas mixing is not sufficient and uniform, which leads to insufficient combustion and waste of resources. At the same time, the combustion produces more nitrogen oxides, which seriously pollutes the air. Contents of the invention [0004] The purpose of the present invention is to provide a gas boiler low-nitrogen combus...
