Problems solved by technology

[0003] In the prior art, in order to use biomass energy more effectively, the combustion technology of biomass shaped particles has been widely used. Biomass fuel has gradually replaced coal, diesel, natural gas, etc. as the main fuel for boiler combustion now. Due to the There are qualitative differences with other energy sources such as coal, diesel, natural gas, etc., so there are great differences in boiler feed, boiler structure design, and combustion design. If it is completely burned, it will coke in the furnace, which will shorten the service life of the boiler

Abstract

The invention provides a biomass boiler. The biomass boiler comprises a boiler body, a hearth combustion chamber arranged inside the boiler body, a water steam system above the combustion chamber, a smoke exhaust port communicated with the combustion chamber, a draught fan connected with the smoke exhaust port through a pipeline, and a movable fire gate which is arranged at the bottom of the combustion chamber and extends towards the discharging direction, wherein a primary air inlet chamber is arranged below the fire gate, a secondary air inlet chamber is arranged above the fire gate, an electric spiral feeding device is arranged in the feeding position of the fire gate, and an electric spiral slag outlet device is arranged in the discharging position of the tail end of the fire gate. The biomass boiler is simple in structure, high in heat efficiency, sufficient and stable in combustion and low in operation cost, saves the operation cost by about 10% compared with a coal-fired method, and saves more energy.

Description

technical field [0001] The invention relates to a biomass boiler, which belongs to the technical field of boilers. Background technique [0002] Biomass fuel is a renewable energy source. Biomass combustion technology is undoubtedly suitable for my country's energy development needs. Biomass boilers have received more and more attention and research and development. [0003] In the existing technology, in order to use biomass energy more effectively, the combustion technology of biomass shaped particles has been widely used. Biomass fuel has gradually replaced coal, diesel, natural gas, etc. as the main fuel for boiler combustion now. Due to biomass fuel There are qualitative differences with other energy sources such as coal, diesel, natural gas, etc., so there are great differences in boiler feed, boiler structure design, and combustion design. If it is completely burned, it will coke in the furnace, which will shorten the service life of the boiler. Contents of the inv...
