Abstract

The utility model relates to an energy-saving heating stove second air-return smoke-free stove core, and in particular relates to a second air-return stove core that adopts the biomass as the fuel, which consists of an upper conical stove core and a lower conical stove core; a second air-return ring (2) is arranged at the upper periphery of the upper cone of the stove core (5); an air inlet (4) is arranged below the second air-return ring; a second air inlet (3) is arranged on the wall of the upper conical stove core (5) inside the second air-return ring (2); a smoke-absorption hole (6) is arranged on the upper conical stove core wall below the second air-return ring (2); the lower conical wall of the stove core (5) is provided with an air inlet hole (7); a stove-core outlet (1) is arranged above the stove core (5); and a fire-closing switch outlet (8) is arranged at the lower part of the stove core (5). The stove core of the utility model is rapid to build a fire and to conduct the heat, and is free from smoke and insipidity, and has long service life, and can protect the environment and save the energy, and is applicable to stove combusting the biomass fuel.

Description

The smokeless combustion chamber of energy-conservation burner stove secondary return air

Technical field:

The utility model relates to burner stove combustion chamber, the smokeless combustion chamber of particularly a kind of energy-conservation burner stove secondary return air.

Background technology:

Stove and accessory of the prior art mostly is coal furnace, and this stove and accessory is on fire slow, and spent fuel is many, and dust is big, and environmental protection is poor.

Summary of the invention:

The purpose of this utility model is to provide a kind of energy-conservation burner stove secondary return air smokeless combustion chamber, and the living beings of utilizing this combustion chamber can burn and go out of use are on fire fast, and it is fast to conduct heat, the normal back of burning smoke-free and tasteless, and long service life can reach the purpose of environmental protection and energy saving.

Formation of the present utility model: form by combustion chamber and secondary return air circle, combustion chamber 5 is made up of two conical combustion chambers up and down, secondary return air circle 2 is set around above circular cone on the combustion chamber 5, air inlet 4 is arranged below the secondary return air circle, on conical combustion chamber 5 walls secondary intake opening 3 is arranged in secondary return air circle 2, smoking-hole 6 is arranged on the conical furnace core wall on below secondary return air circle 2, on the following conical walls of combustion chamber 5, fresh air inlet 7 is arranged, combustion chamber outlet 1 is arranged, the below switch outlet 8 of banking up a fire above combustion chamber 5.

The last conical combustion chamber of combustion chamber 5 is head-up little, and greatly upside down, the following conical combustion chamber of combustion chamber 5 greatly head-up, and is upside down little, and conical up and down combustion chamber major part is connected to form one.

Compared with the prior art, the utility model combustion chamber is formed uniform secondary intake opening, smoking-hole and fresh air inlet on furnace core wall by conical combustion chamber up and down, bank up a fire switch outlet of bottom has the secondary return air circle around the secondary intake opening of the top of upper conical combustion chamber, there is air inlet secondary return air circle below, utilize such combustion chamber biomass burning class A fuel A, on fire fast, it is fast to conduct heat, the normal back of burning smoke-free and tasteless, only needed two jin of dried fuel in one hour, reach service life more than 3 years, environmental protection, energy-conservation.

Description of drawings:

Accompanying drawing is the utility model structural representation.

1. combustion chambers outlet among the figure, 2. secondary return air circle, 3. secondary intake opening, 4. air inlet, 5. combustion chamber, 6. smoking-hole, 7. fresh air inlet, the switch of 8. banking up a fire outlet.

The specific embodiment:

As shown in the figure, combustion chamber 5 is made up of two conical combustion chambers up and down, secondary return air circle 2 is set around above circular cone on the combustion chamber 5, air inlet 4 is arranged below the secondary return air circle, on conical combustion chamber 5 walls secondary intake opening 3 is arranged in secondary return air circle 2, smoking-hole 6 is arranged on the conical furnace core wall on below secondary return air circle 2, on the following conical walls of combustion chamber 5, fresh air inlet 7 is arranged, combustion chamber outlet 1 is arranged, the below switch outlet 8 of banking up a fire above combustion chamber 5;
