Upper combustion and balanced oxygen supply type biomass particle cooking furnace

Abstract

The invention discloses an upper combustion and balanced oxygen supply type biomass particle cooking furnace. The upper combustion and balanced oxygen supply type biomass particle cooking furnace comprises a combustion hearth containing cavity arranged inside the furnace wall; a secondary air inlet sleeve containing cavity is arranged at the upper end of the combustion hearth containing cavity in a communicating mode; a primary air inlet sleeve containing cavity is arranged at the lower end of the combustion hearth containing cavity in a communicating mode; a combustion hearth with an upper opening and a lower opening is arranged inside the combustion hearth containing cavity; a secondary air inlet sleeve with an upper opening and a lower opening is arranged inside the secondary air inlet sleeve containing cavity; air inlet holes are evenly formed in the secondary air inlet sleeve in the circumferential direction; a primary air inlet sleeve with an upper opening and a lower opening is arranged inside the primary air inlet sleeve containing cavity; multiple circles of streamline air inlet holes are formed in the primary air inlet sleeve in the circumferential direction; the lower opening of the primary air inlet sleeve is closed by a fire grate; and a draught fan communicates with the secondary air inlet sleeve containing cavity and the primary air inlet sleeve containing cavity through air flues correspondingly. Biomass particles are combusted sufficiently, fire is strong, the combustion time is long, the content of carbon oxide in exhausted smoke gas is low, and energy conservation and environmental protection of combustion of biomass particle fuel are achieved.

Description

technical field [0001] The invention relates to the technical field of combustion equipment for biomass particles, in particular to an upward combustion balanced oxygen supply type biomass particle cooking stove. Background technique [0002] According to my country's agricultural product calculations, the total amount of straw resources in my country is about 700 million tons per year, of which corn, rice and wheat have the highest straw yields, accounting for about 37.4%, 24.2% and 13.3% of the total crop straw, and oil crops account for about 10% of the total crop straw, beans accounted for about 5% of the total crop straw. At present, the use of biomass fuel in China is mainly in rural areas, most of which are traditional utilization and direct combustion, which is inefficient. The inefficient and wasteful use of biomass fuel will not only lead to energy shortages in some areas, but also cause damage to the ecological environment. . [0003] In order to make reasonable ...

Problems solved by technology

However, the commonly used stoves use a bottom-up combustion method after the fuel is ignited. The firepower in the cooking combustion is not strong, and it needs to be continuously fed from the top to ensure the cooking needs, and there are biomass pellet fuels that burn quickly and insufficiently. , long cooking time, unstable emissions from combustion stoves, and excessive carbon monoxide
