Charcoal stove

Abstract

The invention discloses a firewood coal furnace. The number of coal adding openings is at least one, an inner cavity of a furnace body is divided into a combustion supporting cavity in the upper portion and a combustion cavity in the lower portion, a second furnace opening communicating the combustion supporting cavity with the combustion cavity is formed in the furnace body, and a first furnace opening is formed in the position, corresponding to the second furnace opening, of the top of the furnace body; a temperature increasing cylinder which is arranged in a downwards-stretching manner is fixedly arranged on the second furnace opening in the furnace body, a plurality of air passing channels are formed in the position, close to the end of the second furnace opening, of the wall of the temperature increasing cylinder, the bottom end of the temperature increasing cylinder is located below the coal adding openings, and an air supply pipe with the outer end communicating with the exterior air and the inner end communicating with the combustion supporting cavity is arranged in the furnace body; the temperature increasing cylinder is arranged in the furnace body, the air passing channels are formed in the upper segment of the temperature increasing cylinder, smoke can enter the combustion supporting cavity to be combusted, the air supply pipe is arranged, air enters the furnace openings from the bottom of the furnace body to be subject to oxygen supporting combustion, in the combustion process, the heat value is higher, the efficiency is higher, no smoke or odor or tar exists, and the bottom of a pan is not blackened.

Description

technical field [0001] The invention relates to a firewood stove. Background technique [0002] At present, the well-known rural firewood stoves in my country and the world are mostly self-made masonry simple stoves. The crude cast iron or metal simple stoves and general gasification firewood stoves purchased will not burn firewood, coal (especially low-quality coal) during use. Sufficient and extremely low efficiency, it wastes the time and energy of the user while causing energy waste, and the thick smoke and dust it produces seriously pollute the environment, and the harmful gas directly endangers the physical and mental health of the user. At present, some gasification charcoal stoves are in use, but the existing gasification charcoal stoves have low combustion temperature, insufficient combustion, and coal tar and dust pollute the environment. According to data released by the Global Alliance for Clean Stoves, about 3 billion people around the world burn traditional bio...
