Biomass combustion machine

Abstract

The invention provides a biomass combustion machine which comprises a combustion chamber, a feeding device communicated to one side of the combustion chamber and a flame outlet device communicated to the other side of the combustion chamber. The flame outlet device comprises a flame outlet pipe communicated with the combustion chamber and a cooling pipe installed on the periphery of the flame outlet pipe, wherein the cooling pipe is communicated with a liquid layer arranged on the outer wall of the combustion chamber and used for reducing the temperature of the flame outlet pipe so as to carry away heat, and the service life of the flame outlet pipe can be prolonged. The feeding device comprises a raw material hopper, a feeding pipe connected with the raw material hopper and a blanking port, wherein the blanking port is connected between the feeding pipe and the combustion chamber, one end of the feeding pipe is connected with an air distribution machine, and a blanking baffle capable of controlling biomass fuel to be evenly distributed in the combustion chamber is assembled in the blanking port. The biomass fuel falls into the combustion chamber through the blanking baffle and can be evenly distributed in the combustion chamber by adjusting the blanking baffle, the phenomenon that the biomass fuel is centralized and piled together in the prior art is avoided, the fuel can be efficiently combusted, and energy conversion rate is improved.

Description

technical field [0001] The invention relates to fuel equipment, in particular to a biomass burner. Background technique [0002] Biomass burner is mainly developed for boilers and other heating needs. It uses abundant corn stalks, wood chips, and crop stalks in the countryside as raw materials, and is compressed into regular-shaped and uniform-sized pellet fuels by molding equipment. The high-efficiency incineration is converted into heat energy by the fully automatic particle incinerator, and the heat produced by incineration is absorbed by the circulating water in the boiler. [0003] In the existing biomass burner, the feed device of the burner includes a raw material hopper and a feed pipe connected to the raw material hopper. Biomass fuel is stored in the raw material hopper, and the feed pipe is connected to the combustion chamber provided by the burner. One end of the pipe is connected to a fan, which is used to blow the biomass fuel in the feed pipe into the combust...

Problems solved by technology

[0003] In the existing biomass burner, the feed device of the burner includes a raw material hopper and a feed pipe connected to the raw material hopper. Biomass fuel is stored in the raw material hopper, and the feed pipe is connected to the combustion chamber provided by the burner. One end of the pipe is connected to a fan, which is used to blow the biomass fuel in the feed pipe into the combustion chamber. However, the biomass fuel entering the feed pipe will accumulate in a certain place in the combustion chamber. , will cause insufficient fuel combustion and low energy conversion rate; and the fire outlet pipe of the biomass burner has been working at high temperature for a long time, so that the general fire outlet pipe will be scrapped after a period of use, the service life is not long, and at high temperature It is more troublesome to replace in the environment
