High-water-content biomass fuel boiler

Abstract

The invention discloses a high-water-content biomass fuel boiler which comprises a hearth and a flue. Multiple collecting boxes are arranged on the wall of the hearth and the wall of the flue. A separation wall with an upper opening is arranged in the hearth to divide the hearth into a front supply area and a rear supply area, a chain type fire grate is arranged on the lower portion of the front supply area, the upper portion and the middle portion of the rear supply area are transversely arranged in the rear supply area and provided with an upper boiler barrel and a lower boiler barrel respectively, the upper portion of the front supply area protrudes upwards and backwards and is connected to the upper boiler barrel through the collecting boxes, a convection bank and a separation plate are arranged between the upper boiler barrel and the lower boiler barrel, an ash discharge hopper is arranged at the bottom of the separation wall and the bottom of the rear portion of the hearth, an air preheater is arranged in the flue, the upper portion of the flue is connected to the lower portion of the front supply area of the hearth, and a coal economizer is arranged in the flue and connected to the upper boiler barrel through the collecting boxes. The high-water-content biomass fuel boiler can solve the problems that an existing biomass boiler incinerates and disposes high-water-content biomass materials such as traditional Chinese medicine waste residue difficultly and is low in thermal efficiency, and discharged smoke pollutes the environment.

Description

technical field [0001] The invention relates to the technical field of biomass fuel equipment, in particular to a boiler for burning biomass fuel with high water content. Background technique [0002] Chinese herbal medicine waste residues and other resources have always been wasted by people, causing a lot of environmental pollution. If it can be used as biomass energy to replace fossil fuels, it can reduce the content of carbon dioxide, sulfur dioxide and nitrogen oxides in the atmosphere. , the implementation of energy sustainable development strategy has important practical significance. [0003] However, at present, the implementation and utilization of Chinese herbal medicine waste residues as biomass energy in small and medium-sized enterprises is still very small. The reason is found: the existing biomass boilers generally include the furnace and the flue extending downward from the upper part of the furnace, and the Chinese herbal medicine waste residues and other ...
