The invention provides a boiler feeding system, which includes a hopper, a screw feeder, a distributor, and an air inlet device; the screw feeder includes a feeding pipe and a screw shaft located in the feeding pipe, and the feeding One end of the material pipe is provided with a feed inlet on the upper wall, the other end of the lower pipe wall is provided with a discharge port, and the upper pipe wall corresponding to the position of the discharge port is provided with an air inlet, and the feed port is connected to the hopper , the discharge port is connected with the distributor, and the air inlet is connected with the air inlet device. The beneficial effects of the present invention are: since an air inlet is provided above the outlet of the screw feeder, the air inlet is connected with the air inlet device, so that the wind generated by the air inlet device can be blown into the screw feeder, After that, it is blown into the distributor, which promotes the downward movement of the fuel and prevents the burned fuel from burning upwards and backwards. At the same time, it can also cool down the distributor to avoid reddening and deformation of the distributor due to excessive temperature. .
Description
technical field [0001] The invention relates to the field of boilers, in particular to a boiler feeding system. Background technique [0002] For boilers with feeding system, since the distributor of the feeding system is located at the front arch of the boiler, the high temperature of the boiler arch will not only radiate and affect the distributor, but may even cause the fuel to burn back, which is easy Make the dispenser red and deformed. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a boiler feeding system that is convenient for protecting the distributor. [0004] In order to solve the above technical problems, the technical solution of the present invention is: a boiler feeding system, including a hopper, a screw feeder, a feeder, and an air inlet device; the screw feeder includes a feeding pipe and a The screw shaft in the tube, one end of the feeding pipe is provided with a feed inlet on the upper pipe wall, ...
