Abstract

The invention relates to a feeding system of a biomass boiler, and in particular to a boiler distributor not prone to burning-out. A feeding opening in the upper end of the distributor is connected with a discharging opening of a spiral feeding machine. A discharging opening in the lower end of the distributor is formed above a fire grate of a boiler. The periphery of the distributor is wrapped with a ring of protection cover. A cavity is formed between the protection cover and the distributor. The protection cover is provided with a cooling fan tube seat which is used for being connected with a cooling fan. According to the technical scheme, the periphery of the distributor is provided with the protection cover, and the distributor can be separated from a boiler front panel; the cavity is formed between the protection cover and the distributor, and cooling air is blown into the cavity through the cooling fan, so that it is avoided that high temperature of the front panel radiates the distributor, and the situation that the overall attractiveness of the boiler is affected due to the fact that paint of the distributor falls off is prevented; and the service life of the distributor is prolonged.

Description

technical field [0001] The invention relates to a feed system of a biomass boiler, in particular to a feed distributor of a biomass boiler. Background technique [0002] In the prior art, the feeder of the biomass boiler is close to the front panel of the boiler, and the high-temperature radiation of the front panel is likely to cause paint stripping and deformation of the feeder, which not only affects the appearance, but also long-term high-temperature radiation will damage the feeder. The pipe wall is burnt. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a boiler feeder that is not easy to be burned out by the high temperature radiation of the front panel of the boiler. [0004] In order to solve the above technical problems, the technical solution of the present invention is: a boiler feeder that is not easy to be burned out, the feed inlet at the upper end of the feeder is connected with the discharge port...
