Burning-speed-controllable coal storage and vaporization integral hot-blast stove special for greenhouse

Abstract

The invention discloses a burning-speed-controllable coal storage and vaporization integral hot-blast stove special for a greenhouse. The hot-blast stove is composes of a front stove body and a back stove body which are communicated through a flue gas channel on the lower portions of the front stove body and the back stove body. The front stove body is composed of a coal stove upper cover, smoke separated sand, an exhaust pipe, a coal storage bunker, a refractory soil layer, a coal hopper, a coal stove fire door, a coal fired hearth, a stove grate, a coal stove ash hearth and a coal stove ash discharging door. The back stove body is composed of a smoke outlet, an outer barrel, hot air pipes, an air outlet, a cooling fin, an inner barrel, a heat exchange chamber, an air channel, an oxygenating opening, an air inlet, a steam stove ash discharging outlet and a steam stove ash hearth.

Description

technical field [0001] The invention relates to a coal-storage and gasification integrated hot blast stove with controllable combustion speed for greenhouses, which utilizes the secondary combustion principle of coal to fully burn the coal in the furnace to achieve high heating efficiency, environmental protection and energy saving, and belongs to the field of agricultural equipment. Background technique [0002] With the development of facility agriculture in our country, greenhouse cultivation is used more and more in winter, especially in the north. However, due to the extreme weather every year, hot blast stoves must be equipped for facility agricultural production operations. Xinjiang is the main coal production area in the country, and the price of coal is relatively low. Therefore, coal is the main energy source for hot blast stoves. The following occurs during the use of ordinary coal-fired hot blast stoves question: [0003] 1. During the use of ordinary coal-fired...

AI Technical Summary

Problems solved by technology

[0003] 1. During the use of ordinary coal-fired hot blast stoves, too much coal cannot be added at one time, and the workload of adding coal is huge

[0004] 2. The burning time of coal is short and cannot be fully burned

[0005] 3. There will be smoke falling from the hot blast stove, and harmful gases such as CO will enter the air, causing harm to personnel and crops
