Abstract

The invention discloses a bundling direct-burning type straw boiler, and relates to an improvement of a boiler structure. By means of the bundling direct-burning type straw boiler, straw is directly bundled through special equipment in the field and conveyed to a boiler room, and then the straw can be directly burnt, and the burning cost is reduced. The bundling direct-burning type straw boiler comprises a boiler body with a primary air tube and a secondary air tube, a fuel inlet is formed in the front end of the boiler body, a conveying belt type fire grate is arranged in the boiler body, and the front end of the fire grate extends out from the fuel inlet and is arranged outside the boiler body; and a front arch and a rear arch are arranged at the positions, corresponding to the fire grate, in the boiler body, and an outlet of the secondary air tube of the boiler body is arranged in the front arch and the rear arch. The bundling direct-burning type straw boiler is structurally characterized in that an inlet of the secondary air tube of the boiler body is formed in the back end of the boiler body, and the secondary air tube of the boiler body is arranged in a boiler wall passing through a hearth; and an included angle formed between the front arch and the horizontal plane is larger than or equal to 55 degrees and smaller than or equal to 70 degrees.

Description

technical field [0001] The invention relates to an improvement of a boiler structure. Background technique [0002] When the current straw is used as boiler fuel, it must be mechanically processed to produce granular or blocky biomass fuel, which increases power consumption, processing costs and transportation costs, making the cost of straw fuel equal to or more than coal-fired cost of. Contents of the invention [0003] The present invention aims at the above problems, and provides a bundled direct-fired straw boiler in which the straw is directly bundled into bundles with special equipment in the field, and can be directly used for combustion after being transported to the boiler room, thereby reducing fuel costs. [0004] In order to achieve the above-mentioned purpose of the present invention, the present invention adopts following technical scheme, the present invention comprises the furnace body that has primary air duct and secondary air duct, the front end of fur...
