The invention discloses a combustion-velocity-controllable coal storage-gasification hot blast stove dedicated to a greenhouse. The hot blast stove is characterized in that a room temperature sensor arranged on a temperature controller is electrically connected with an active air supply fan mounted on an inspection door; an active air supply pipe is connected with a combustion chamber and the active air supply fan; when room temperature is lower than the set temperature, the active air supply fan works; when room temperature is higher than the set temperature, the active air supply fan stops working, so that the combustion velocity of the coal hot blast stove can be controlled; a heat exchange cavity arranged on one side of a secondary combustion chamber communicates with a heat exchange pipe and a smoke cavity; after communicating with each other, the heat exchange cavity and the heat exchange pipe communicate with a hot air outlet; heated air enters the greenhouse through the hot air outlet; and the smoke cavity communicates with a smoke vent, so that exhaust air in the smoke cavity is discharged through the smoke vent. According to the hot blast stove provided by the invention, the combustion velocity is controllable; by utilization of twice coal combustion, coal can be sufficiently combusted in a hearth; and accordingly, the effects of high heating efficiency, environmental protection and energy conservation can be achieved.
Description
technical field [0001] The invention belongs to the field of thermodynamic machinery, and in particular relates to a coal-storage gasification hot air stove with controllable combustion speed specially for greenhouses. 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. The price of coal is relatively low, so coal is the main energy source for hot blast stoves. The following problems arise during the use of ordinary coal-fired hot blast stoves: [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 st...
