Biomass combustion furnace with controllable combustion intensity

Abstract

The invention provides a biomass combustion furnace with controllable combustion intensity, and belongs to the field of biomass combustion furnaces. The biomass combustion furnace with controllable combustion intensity comprises a furnace body, a smoke collecting hood and a chimney connecting pipe; the furnace body is internally provided with a biomass burner; the smoke collecting hood cover the furnace mouth; and the chimney connecting pipe communicates with the smoke collecting hood and is provided with a chimney connector and an air inlet with an adjustable opening area. When the furnace isused, the suction force of the chimney to the smoke collecting hood is reduced by increasing the opening area of the air inlet, and the combustion in the hearth is slowed down; and by decreasing theopening area of the air inlet, the suction force of the chimney to the smoke collecting hood is increased, and the combustion in the hearth is accelerated. According to the controllable smoke discharging structure, air is sucked from the air inlet, so that the suction force of the chimney to the smoke collecting hood is reduced, the combustion in a hearth is slowed down, meanwhile, the passage from the smoke collecting hood to the chimney via the chimney connecting pipe is kept smooth all the time, smoke generated at the furnace mouth of the furnace body can still be discharged outward via thechimney through the smoke collecting hood and the chimney connecting pipe, and people in a room are protected against carbon monoxide poisoning.

Description

technical field [0001] The invention belongs to the technical field of biomass combustion furnaces, and more specifically relates to a biomass combustion furnace with controllable combustion intensity. Background technique [0002] The fuel used in the biomass burning furnace is biomass fuel such as biomass briquettes. Compared with coal and other fuels, biomass fuel is easier to burn, so the biomass burning furnace burns very vigorously and is easy to use, but it is also easy to cause biomass The combustion in the combustion furnace is difficult to control, and it is prone to the problems of short fuel combustion time and frequent filling. Therefore, how to effectively control the combustion in the furnace of the biomass combustion furnace has become an urgent problem to be solved. [0003] The existing biomass combustion furnace is equipped with a smoke collection hood at the furnace mouth, and the smoke collection hood is connected with the chimney. It also speeds up the...

Problems solved by technology

[0004] The purpose of the present invention is to provide a biomass combustion furnace with controllable combustion intensity to solve the problem that the combustion in the biomass combustion furnace in the prior art is difficult to control, and the existing communication between the smoke collection hood and the chimney is blocked. The method of slowing down the combustion prevents the flue gas from being discharged to the outside, which is likely to cause technical problems of carbon monoxide poisoning of indoor personnel.
