A biomass briquette fuel solid-phase low-temperature, gas-phase high-temperature combustion device

Abstract

The utility model relates to a solid-phase low-temperature and gas-phase high-temperature combustion device for biomass briquette fuel, which belongs to the technical field of biomass combustion. It is characterized in that: the feed port of the smoldering zone (3) communicates with the discharge port of the furnace (1), the discharge port of the smoldering zone (3) communicates with the cooling zone (4), and the lower part of the furnace (1) is equipped with There is a grate (13), the grate (13) is equipped with a crushing mechanism (2) for crushing materials, and the grate (13) is connected with a rotating mechanism to disturb the biomass fuel and make the carbon powder fall into the The smoldering area (3) is smoldering, and at the same time, the block biomass fuel is moved to the middle of the grate (13), and the crushing mechanism (2) breaks the block biomass fuel into carbon powder and falls into the smoldering area (3). burn. The solid-phase low-temperature and gas-phase high-temperature combustion device for biomass briquette fuel solves the problems of coking, slagging, high emission of gas-solid pollutants and failure of ash fertilizers from the root causes of agricultural waste burning equipment such as straw.

Description

technical field [0001] The utility model relates to a solid-phase low-temperature and gas-phase high-temperature combustion device for biomass molding fuel, which belongs to the technical field of biomass combustion. Background technique [0002] With the adjustment of agricultural structure and the development of rural economy in China, it is urgent to solve the problems of distributed small-scale heating such as drying of agricultural products and heating of agricultural facilities. For example, the mechanization level of grain drying in my country is 10% (the level of 80-90% in Japan and South Korea), and the loss of wet grains, such as mildew, is as high as 5% (less than 1% in developed countries). There is an urgent need to develop drying machinery and its supporting medium and small heating devices (generally less than 2.8MW). The heating demand of agricultural facilities (livestock and poultry houses, greenhouses, etc.) in 2 / 3 of my country's land area is also extrem...
