Abstract

The invention provides a flue gas recirculation system, which belongs to the technical field of machinery. The problem that in the prior art, stability is poor is solved. The flue gas recirculation system comprises a boiler, a combustor, an air blower, a flue and an air mixing assembly. The combustor is connected with the boiler. The flue is connected to the smoke outlet of the boiler. The air mixing assembly is communicated with the flue through a first connecting pipe. The combustor is communicated with the air mixing assembly through a second connecting pipe. The air blower is connected with the second connecting pipe in series. The flue gas recirculation system is high in stability.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a flue gas recirculation system. Background technique [0002] During the use of the boiler, the air is directly input into the burner. Because the air temperature is relatively low, this may cause insufficient combustion of the burner and affect the operating efficiency of the boiler. Contents of the invention [0003] The object of the present invention is to provide a flue gas recirculation system with high stability and compact structure in order to solve the above-mentioned problems in the prior art. [0004] The purpose of the present invention can be achieved through the following technical solutions: [0005] A flue gas recirculation system, characterized in that it includes a boiler, a burner, a blower, a flue and an air mixing assembly, the burner is connected to the boiler, the flue is connected to the smoke outlet of the boiler, and the air mixing assembly The firs...
