High-combustion-efficiency biomass combustion boiler with energy recovery link

Abstract

The invention discloses a high-combustion-efficiency biomass combustion boiler with an energy recovery link, which comprises a boiler body, wherein an energy recovery and conversion mechanism is fixedly installed on one side of the boiler body, a combustion chamber is arranged at the upper end of the interior of the boiler body, and a fire grate mechanism is arranged at the bottom of the combustion chamber; an ash chamber is arranged below the fire grate mechanism, the fire grate mechanism comprises a fixed fire grate fixedly installed at the bottom of the combustion chamber and a movable fire grate slidably installed under the fixed fire grate, a lifting frame is fixedly installed on one side of the movable fire grate, and vertically-arranged sliding rods are slidably installed at the two ends of the lifting frame; the upper ends and the lower ends of the two sliding rods are fixedly connected with fixing bases installed on the outer wall of the ash chamber, rail grooves are formed in the outer side wall of the lifting frame, and a servo motor installed on the inner wall of the boiler body is arranged on the outer side of the lifting frame. The energy recovery and conversion mechanism can convert heat of the outer wall of the combustion chamber into electric energy for storage and application, and is energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of biomass combustion boilers, in particular to a biomass combustion boiler with an energy recovery link and high combustion efficiency. Background technique [0002] Biomass combustion boiler is an environmentally friendly equipment that burns biomass fuel. [0003] Existing biomass combustion boilers generally do not have a heat recovery link, and there will be more heat on the outer wall of the combustion chamber during the combustion process, so the energy utilization of existing biomass combustion boilers is not efficient enough; in addition, the fuel in the combustion chamber is accumulating After reaching a certain level, the bottom of the fuel will be tighter, and there will be less air, and it will be difficult for the air supply mechanism to deliver air to the bottom of the fuel, which will lead to insufficient combustion of the fuel; in addition, the fuel ash after burning also needs to be removed...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a biomass combustion boiler with high combustion efficiency with an energy recovery link, to solve the problem that the existing biomass combustion boilers proposed in the above background technology generally do not have a heat recovery link, and burn during the combustion process. There will be more heat on the outer wall of the chamber, so the energy utilization of the existing biomass combustion boilers is not efficient enough; in addition, after the fuel in the combustion chamber is accumulated to a certain extent, the bottom of the fuel will be relatively tight, and there will be less air, and the delivery It is also difficult for the air mechanism to transport air to the bottom of the fuel, which will lead to insufficient combustion of the fuel; in addition, the burned fuel ash needs to be removed in time to prevent it from wrapping the unburned fuel and affecting its combustion efficiency
