Problems solved by technology

Most of the traditional biomass combustion boilers are traditional boilers. This kind of traditional boiler uses exhaust fan to draw air to generate negative pressure in the combustion chamber, so that the fuel can be burned under negative pressure. In this state, there is no fuel in the combustion chamber. After full combustio...

Abstract

The invention discloses a biomass combustion boiler. The biomass combustion boiler comprises an outer shell and an internal combustion chamber, wherein a water storage chamber is arranged between the shell and the combustion chamber; the lower part of the combustion chamber is provided with a fire grate; the fire grate comprises a fist round support pipe fit with the inner wall of the combustion chamber and a plurality of rib pipes which are horizontally arranged on a first round support pipe side by side; the first round support pipe and the rib pipes are provided with a plurality of upper air exhaust holes which exhaust air upwards; a second round support pipe close to the inner wall of the combustion chamber is arranged above the fire grate, and is provided with a plurality of vertical air blowing pipes communicated with the second round support pipe; the second round support pipe and the vertical air blowing pipes are provided with a plurality of radial air exhaust holes; the first round support pipe and the second round support are both communicated with an air outlet of the fan via connecting pipelines; the side surface of the shell is provided with a fuel charge pipe communicated with a packing auger outlet which is communicated with a fuel charge hopper. According to the biomass combustion boiler, by changing the structure of the fire grate and the air supplying mode of combustion supporting air, fuels are combusted fully, and the combustion efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to a biomass combustion boiler. Background technique [0002] As we all know, biomass is waste from agricultural and forestry production. If it is discarded and incinerated at will, it will seriously pollute the environment. Using biomass to incinerate in a boiler, the steam generated is used for power generation or heating, which has a society that saves energy and reduces environmental pollution. Benefits also have good economic benefits. Most of the traditional biomass combustion boilers are traditional boilers. This kind of traditional boiler uses exhaust fan to draw air to generate negative pressure in the combustion chamber, so that the fuel can be burned under negative pressure. In this state, there is no fuel in the combustion chamber. After full combustion, it will be sucked out of the combustion chamber by the wind, so it cannot make full use of the characteristics of hig...
