Problems solved by technology

[0008] To sum up, the biomass combustion furnaces currently on the market mainly burn biomass briquettes, and its structure is generally that there is an inclined feed pipe between the feeding part and the furnace hearth of the combustion furnace. The biomass briquettes are under the action of gravity This structure can realize the function of anti-backfire and anti-smoke, but this structure is not suitable for burning biomass scrap fuel

Embodiment 2

[0073] A rural family adopts the present invention to heat the family room. The family has indoor heating equipment. Here, the heat exchanger 8 in the furnace of the present invention is directly connected to the interface of the original heating equipment. The heat exchange outside the furnace and the waste heat utilization device 10 Connect the hot water insulation tank of the family to provide domestic hot water. And the feeding bin 15 is slightly lower than the ground, and the bulk biomass material can be easily poured into the bin. Due to factors such as capital and site, the tail gas purification device 11 is not used, and the control system is not used in the whole process. It is to realize the function of automatic feeding and automatic ash discharge. The ash falls into a large container slightly below the ash outlet and is manually cleaned the next day.

[0074] The biomass scraps mainly burned are corn stalks, wheat straws, and the mixture of the above scraps and co...

Embodiment 3

[0076] A grain drying enterprise adopts the patent of the present invention as the energy supply device, and sends the air preheated by the heat exchange and waste heat utilization device 10 outside the furnace into the biomass combustion furnace through the fan 18, mainly preheating the cold air, and passing it through the fan 18. It is passed into the furnace, and the air required for combustion is preheated to achieve the purpose of energy saving. At this time, all the systems mentioned in the present invention are adopted, including the control system and the detection system. And it is integrated into the control cabinet with its drying system. At this time, the circulating medium in the heat exchanger 8 in the furnace is the heat carrier air of the drying box. A cyclone dust collector, that is, an exhaust gas purification device 11, is arranged to remove dust from the flue gas and discharge it into the atmosphere. At the same time, the temperature sensor is arranged at t...

Abstract

The invention discloses an inclined feeding type agricultural and forestry biomass particle combustion furnace. A feeding bin, a biomass combustion furnace body, an external heat exchange and waste heat utilization device and a tail gas purification device are all installed on a movable base; a fireproof and thermal-insulation partition board is arranged at the upper part of the feeding bin, a primary feeding device is arranged at the bottom of the feeding bin, and the tail part of the primary feeding device is connected with a biomass combustion furnace body by a secondary feeding device; theexternal heat exchange and waste heat utilization device is connected to an outlet of the biomass combustion furnace body, and the tail gas purification device is connected to the back of the external heat exchange and waste heat utilization device; an internal heat exchanger is arranged in the biomass combustion furnace body; the fireproof and thermal-insulation partition board is installed at the upper end of the feeding bin, and an automatic door closer is also installed on the fireproof and thermal-insulation partition board. The combustion furnace has the characteristics of being energy-saving and environmentally friendly and operating automatically, and can have broad prospects in rural heating in mountainous areas of China.

Description

technical field [0001] The invention relates to a biomass scrap combustion equipment, in particular to an inclined feeding type agricultural and forestry biomass scrap combustion furnace. Background technique [0002] Biomass combustion furnace has the advantages of high efficiency, environmental protection, energy saving, etc., high thermal efficiency, low smoke and dust emissions, also known as high-efficiency low-emission furnace, can burn biomass (firewood, straw, sawdust, chaff, leaves, etc.), or biomass Co-firing with coal. The biomass combustion furnace first gasifies the biomass entering the high-temperature furnace to generate combustible gas. The combustible gas is efficiently burned under the action of the secondary air, so as to improve the thermal efficiency of the furnace and reduce the emission of smoke and dust. [0003] At present, collective heating has not been realized in the vast northern regions of our country, especially in the rural areas of the nort...
