Novel biomass boiler slag-breaking device

Abstract

The invention relates to a novel biomass boiler slag-breaking device. The novel biomass boiler slag-breaking device comprises a slag breaking device body, wherein the slag breaking device body comprises a cam, a cooling pipe, a tooth portion, a water inlet pipe and a water outlet pipe, and the cam is arranged on the inner wall of a biomass boiler and moves on the horizontal plane. The cooling pipeis horizontally disposed above a chain grate, and the water inlet pipe and the water outlet pipe are separately connected to the two ends of the cooling pipe. The tooth portion is arranged on the cooling pipe in a sleeving mode and is inclined upward, the cam abuts against one end of the tooth portion, a compression spring fixedly arranged on the inner wall of the biomass boiler abuts against theother end of the tooth portion, and the tooth portion reciprocates left and right in the longitudinal direction of the cooling pipe under the action of the cam and the compression spring. According to the novel biomass boiler slag-breaking device, waste slag is driven to move forward through the chain grate and is ''lifted up'' by multiple slag breaking teeth arranged before and after, and the tooth portion moves left and right on the cooling pipe under the action of the cam and the compression spring, so that the waste slag is subjected to more violent / stronger destructive power.

Description

technical field [0001] The invention relates to the technical field of biomass boilers, in particular to a novel biomass boiler slag breaking device. Background technique [0002] Biomass pellet fuel is efficient, clean, easy to ignite, CO 2 With the advantages of nearly zero emission, it can replace fossil fuels such as coal and be used in civil fields such as cooking and heating, as well as industrial fields such as boiler combustion and power generation. The density of biomass pellet fuel is 1.0~1.4t / m 3 , the energy density is equivalent to medium bituminous coal, the firepower is long-lasting when used, and the furnace temperature is high. It is a good alternative fuel for coal at present. The biomass pellet fuel is cylindrical or block-shaped, consistent in shape, has good fluidity, and is easy to realize combustion equipment. Automatic control and automatic combustion. [0003] In countries such as Europe and the United States, biomass pellet fuels and supporting h...

AI Technical Summary

Problems solved by technology

[0003] In countries such as Europe and the United States, biomass pellet fuels and supporting high-efficiency combustion equipment have become very popular, but these biomass pellet fuels are mainly wood pellet fuels, which have the advantages of high calorific value, low ash content, and are not easy to slagging after combustion. The biomass briquette fuel is mainly crop straw. Compared with wood pellet fuel, there are great differences in physical properties and chemical components, resulting in differences in combustion characteristics. Straw pellet fuel has high ash content, low ash melting point, The alkali metal content is high, and problems such as slagging and serious ash accumulation in the equipment are prone to occur during the combustion process
