Biomass wood powder burning engine

Abstract

The invention discloses a biomass wood powder burning engine and relates to the technical field of burning equipment. According to the biomass wood powder burning engine, the burning engine can be cooled through air cooling, and the material inlet amount and the air input of the burning engine can be automatically controlled. The main technical scheme of the biomass wood powder burning engine includes that the biomass wood powder burning engine comprises a feeding portion and a burning portion, wherein a burner is connected to a feeding pipe, an oxygen supply component is arranged at one end of the burner, one end of a cooling pipe is connected to a cooling fan, the other end of the cooling pipe communicates with the burner mutually, and a first detector is arranged in the burner and connected to a first controller; when the temperature in the burner is smaller than a preset value, the first controller closes the feeding pipe; and a second detector is arranged in the position of a spray outlet of the burner and connected to a second controller, and when the temperature in the position of the spray outlet of the burner is greater than a preset value, the second controller controls the cold air inlet amount of the cooling fan to be increased. The biomass wood powder burning engine is mainly used for burning biomass wood powder.

Description

technical field [0001] The invention relates to the technical field of combustion equipment, in particular to a biomass wood powder burner. Background technique [0002] With the gradual depletion of traditional fossil energy, the energy crisis and environmental pollution have attracted more and more attention from the society. Biomass energy technology has received widespread attention and recognition for its unique properties of low pollution, sustainability, and neutral carbon emissions; among them, The biomass granulated fuel called "solid natural gas" is currently the most in-depth research and the most widely used biomass energy application technology. [0003] Biomass wood powder burner is a general-purpose biomass pellet fuel comprehensive thermal energy application equipment that has been widely promoted and applied at present; this equipment mainly uses biomass gasification, semi-gasification and direct combustion Plants and other agricultural and forestry biomass...

Problems solved by technology

Due to the heat absorption of the water-cooled wall, from the center of the combustion flame outward, the closer to the water-cooled wall, the lower the temperature. Under normal circumstances, as the temperature decreases, the ash will change from liquid to softened and then solid. If the ash is still When it touches the heating surface while it is in a softened state, it will stick to the heating surface due to being cooled, forming coke, which will cause the superheated steam temperature, reheated steam temperature and desuperheating water to increase, and even cause the steam-water pipe to explode; coking will make the boiler The output is reduced, and in severe cases, the furnace is forced to shut down, which seriously reduces the combustion efficiency of biomass wood powder
