Description

Biomass-burning high-efficiency rotary fire energy-saving furnace

Technical field: The utility model relates to a stove, in particular to a biomass-burning high-efficiency rotary fire energy-saving stove.

Background technology: At present, in the vast rural areas and areas where coal is scarce and firewood is scarce, the secondary air inlet holes of the biomass-burning stoves that people usually use are round holes. Not ideal, a large amount of combustible gas is discharged outside, and because the round hole is easy to block, it is extremely difficult to clean. The feeding port has no inclination angle, so that the feeding cannot be carried out automatically, and the feeding process is cumbersome. Low thermal efficiency and poor combustion effect.

Summary of the invention: The purpose of this utility model is to provide a high-efficiency swirling fire energy-saving biomass-burning furnace. The spiral-shaped air inlet of the energy-saving furnace is used to mix and combust with combustible gas. Concentration, complete combustion, less exhaust emissions and high thermal efficiency.

The utility model is composed of a base, a furnace body, a furnace, a spiral air inlet, a windshield, a feeding port, a flue, a water tank and a furnace panel. The furnace is installed in the furnace above the base. There are oblique spiral air inlet holes around the top of the furnace, there is a circular windshield on the top of the furnace, a lower air intake door is installed at the bottom, a furnace bridge is installed at the bottom of the furnace, and a movable bridge is installed on the furnace bridge. Furnace bridge handle, there is a feeding port on one side of the furnace, and there is a ventilation channel between the furnace and the furnace body, which is connected to the chimney through the exhaust channel and the water tank.

The spiral air inlet is a strip hole, and the inclination angle is distributed around the furnace upper opening in a clockwise or counterclockwise direction.

A water tank may or may not be installed between the exhaust duct and the chimney.

The feeding port is set as an upward slope.

Compared with the prior art, when the helical air inlet hole of the utility model is mixed with the combustible gas, the flame concentrates toward the center of the furnace in a rotating shape, so the firepower is more concentrated, the combustion is complete, and the exhaust gas emission is small. The inclined design of the feeding port enables automatic feeding, which is labor-saving and convenient. A water tank is installed on the exhaust duct to utilize waste heat.

Description of the accompanying drawings: the accompanying drawing is a structural representation of the utility model.

In the figure, 1. windshield, 2. feed port door, 3. feed port, 4. movable furnace bridge handle, 5. lower air intake damper panel, 6. flue exhaust duct, 7. spiral air intake hole, 8. Ventilation channel, 9. Furnace bridge, 10. Ash collection box, 11. Active pipe collar, 12. Water injection vent, 13. Drainage hole, 14. Chimney, 15. Furnace panel, 16. Furnace body, 17. Water tank, 18. Base, 19. Furnace gall, 20. Furnace cover, 21. Support plate.

Specific embodiments: as shown in the figure, there is an ash collection box 10 in the base 18, and a furnace furnace 19 is installed through a support plate 21 in the upper furnace body 16, and oblique spiral air inlets 7 are distributed around the top of the furnace , there is an annular windshield 1 on the top of the furnace, the bottom is installed with a lower air intake door panel 5, a furnace bridge 9 is installed below the furnace 19, and a movable furnace bridge handle 4 is installed on the furnace bridge 9. There is a feed port 3 on the side of the feed port, and a feed port door 2 is installed on the feed port, and between the furnace furnace 19 and the body of heater 16, there is an air duct 8, which is connected with the chimney 14 by the flue exhaust duct 6 and the water tank 17. Annular flue is arranged in water tank 17, and drain hole 13 is arranged on one side of water tank, and water injection exhaust hole 12 and chimney 14 are arranged above. A furnace panel 15 with a furnace cover 20 is installed above the furnace body 16 .

The helical air inlet 7 is a strip hole, and the inclination angle is distributed around the furnace upper opening in a clockwise or counterclockwise direction.

Water tank 17 can be installed between exhaust flue 6 and chimney 14, also can not adorn water tank 17.

The feeding port 3 is arranged as an upward slope.

Working principle: open the lower air inlet door, add biomass fuel from the furnace mouth, ignite and burn, and close the lower air inlet door after burning to a high flame. The air entering the helical air inlet hole is mixed and burned. Since the helical air inlet is arranged in sequence, the air flow rotates according to the rules and moves to the center. At this time, the firepower gathers at the center point, which is more conducive to cooking, cooking and other purposes.
