Embodiment Construction

[0028] see figure 1 , figure 2 , the biomass particle fuel clean combustion boiler is a vertical structure, which is composed of a combustion furnace body 1 and a flue gas water heat exchanger 9 standing side by side. The combustion furnace body 1 is mainly composed of an outer cover 1a and an inner container 3a placed inside the outer cover 1a , the ash discharge drawer 4c placed at the bottom of the inner container 3a and penetrating with the outer wall of the outer cover 1a, the feed bin 2a fixed on the upper part of the outer wall of the outer cover 1a, and the agitator 7 inserted into the inner container 3a.

[0029] Coat one deck insulation layer 1b on the inner side of outer cover 1a. The interior of the liner 3a is divided into a gas combustion chamber 8, a gasification chamber 6 and an ash chamber 5 from top to bottom by an upper end cover 3f, a flame stabilizing plate 3e, an upper grate 3c and a lower grate 3d. Offer 3-8 inclined passages 3h radially on the flame-...

Abstract

Disclosed is a biomass particle fuel clean combustion stove. The biomass particle fuel clean combustion stove is composed of a combustion stove body and a smoke water heat exchanger which are arranged in parallel, and is characterized in that a liner is divided into a fuel combustion chamber, a vaporizing chamber and an ash accumulating chamber through an upper cover plate, a flame stabilization plate, an upper stove grate and a lower stove grate; a feeding pipe arranged at the bottom of a feeding bin penetrates through the lateral wall of an outer cover and the lateral wall of the liner, and is inserted in the vaporizing chamber from outside to inside in an inclined mode; a primary air inlet is formed in the outer lateral side of an ash discharge drawer; a secondary air inlet is formed in the lower portion of the peripheral lateral wall of the outer cover; air vents are formed in the lower portion of the peripheral lateral wall of the combustion chamber of the liner; a smoke duct is arranged on the upper portion of the lateral wall of the combustion chamber of the liner. The biomass particle fuel clean combustion stove ensures that biomass particle fuel is completely and stably vaporized and is complete in combustion and high in temperature, improves combustion efficiency of the fuel, obviously reduces the dust carrying amount in smoke, ensures that smoke generated after fuel combustion is clean, effectively avoids ash accumulation and slagging, improves heat exchange efficiency of heat exchange equipment, and is simple and compact in structure, convenient to operate and low in operating cost.

Description

technical field [0001] The invention relates to a combustion device, in particular to a biomass particle fuel clean combustion boiler. Background technique [0002] As the price of fossil energy continues to rise, the development of various renewable and clean energy sources has been highly valued. Some countries with rich agricultural and forestry biomass resources have taken biomass pellet fuel as the development focus of new energy strategic planning. Biomass pellet fuel is the least investment and highest social benefit in biomass energy. [0003] The granular fuel formed by compressing straw, agricultural and forestry waste and other biomass has an increased density, which is convenient for storage and transportation, and its combustion characteristics have been significantly improved. It has the advantages of less black smoke, strong firepower, sufficient combustion, no fly ash, and cleanliness , and the sources of raw materials are extensive, the price is low, and th...
