Energy-saving furnace with secondary combustion structure

Abstract

The invention discloses an energy-saving furnace with a secondary combustion structure, which aims to provide an energy-saving furnace having the advantages of combustion stability and sufficiency, cleaning and heating evenness, and high heating efficiency. The energy-saving furnace comprises a draught fan (1), a gas channel (2), a furnace chamber (3), a furnace core (6), a furnace hearth (4), a cover plate (5) and a supporting device used for supporting cookware, wherein an air intake area (31), a mixing area (32) and a combustion area (33) are respectively arranged in the furnace chamber (3) from bottom to top; the draught fan (1) is communicated with the air intake area (31); the gas channel (2) extends into the mixing area (32); the bottom of the furnace hearth (4) is provided with acombustion through hole (41); the furnace core (6) is arranged in the combustion area (33); the cover plate (5) is arranged above the combustion through hole (41); a gap is formed between the cover plate (5) and the bottom of the furnace hearth (4) through a support device; the cover plate (5) and the furnace core (6) form a first combustion chamber; and the cover plate (5), the furnace hearth (4) and cookware matched with the furnace hearth (4) form a secondary combustion chamber. The invention can be widely applied to the field of furnaces.

[0002] Gas stoves are widely used in many places. Compared with conventional gas stoves, the application number provided by the applicant is 201010241872.9, and the name is the boiler chamber combined exhaust device and energy-saving stove. A relatively airtight, flat and narrow combustion heat conduction space, because the space is relatively airtight, the heat energy is lost less, the temperature is higher, and the mixture of gas and air with a reasonable ratio is easy to ignite and burn more fully, and also promotes the The temperature in the space can be raised rapidly, so as to achieve the technical purpose of good energy saving effect and less heat loss, and solve the technical problems of large energy loss and low gas utilization rate of conventional gas stoves; Gas installation and energy-saving stove technology is not perfect, there are the following technical defects:

[0003] (1) When the cold furnace is uncovering the pot, the pot pressed on the hearth is uncovered, and the relatively closed combustion space formed by the pot and the hearth is disintegrated immediately, so it is prone to flameout, resulting in unstable operation of the stove. And part of the gas that is not fully burned is leaked;

[0004] (2) The flames coming out of the combustion area of ​​the furnace cavity are too concentrated in a small area at the bottom of the pot, the firepower distribution is not dispersed enough, and the firepower is not uniform enough. The temperature is high, which is unfavorable for cooking to control the heat;

[0005] (3) Since there is only one combustion space, although the combustion space formed by the pot and the furnace is relatively airtight, after all, there is a gap between the pot and the furnace, and it is inevitable that some gas will be discharged from the gap before it is fully burned. , and due to the flame not being completely burnt out, carbon black is produced and the furnace and pans are not clean

[0006] In summary, the existing gas stoves have technical defects such as unstable combustion, uneven heating, insufficient combustion of gas, and unclean combustion.
