Energy-saving coal and firewood gasification furnace

Abstract

The invention discloses a novel gasification energy-saving method for a coal firewood furnace, which belongs to the field of energy conservation and environmental protection, comprises an iron furnace body (9), a lower furnace mouth (5) and an upper furnace mouth (6), and is characterized in that an iron honeycomb briquette spherical flame gasifier (2) is arranged at the bottom end of an iron flame guide pipe (3) which is downwards arranged at the lower furnace mouth (5) in the furnace body (9); a flame gathering cover (5) is installed on the periphery of the bottom end of the iron honeycomb briquette spherical flame gasifier (2), and the iron honeycomb briquette spherical gasifier (4) is finally installed at the top end of an iron flame guide pipe after the iron honeycomb briquette spherical flame gasifier (2) and the iron honeycomb briquette spherical flame gasifier (4) are installed according to the sequence, so that the energy-saving coal firewood gasification furnace is installed. When rising and fleeing to the flame gathering cover, flames are influenced to strike to the iron honeycomb briquette spherical flame vaporizer (2) and enter honeycomb holes in the iron honeycomb briquette shape to heat the iron honeycomb briquette spherical flame vaporizer (4), and the high-temperature flame vaporizer (2) formed after heating (being burnt red) gasifies the passing flames to achieve the purpose of further combustion. The iron honeycomb briquette-shaped flame gasifier (4) installed at the top end of the iron flame guide pipe is used for conducting secondary gasification combustion on flames so as to achieve the energy-saving purpose.

Description

Technical field:

[0001] The invention relates to a new method for saving coal and firewood in a heating and cooking stove, belonging to the field of energy saving. Background technology:

[0002] The current stoves used for heating and cooking are composed of a furnace bottom, a furnace, an upper furnace mouth, a lower furnace mouth, and a smoke exhaust channel. The fuel burns very incompletely in the furnace and easily produces smoke, which affects the use of energy and thermal energy and wastes energy. Summary of the invention:

[0003] The purpose of the present invention is to allow the fuel to be burned, and then the flame is gasified by the iron honeycomb briquettes spherical gasifier arranged at the bottom end of the flame duct below the lower furnace mouth to further burn the flame to achieve the purpose of energy saving. In order to improve the effect of the iron honeycomb briquettes spherical gasifier, a second iron honeycomb briquettes spherical gasifier is installed on the top of the flame duct to perform secondary gasification on the flame to improve the flame gasification and combustion effect. The iron honeycomb briquettes spherical gasifier device can further gasify and burn the smoke in the flame, making the exhausted smoke smoke smokeless, thereby achieving the purpose of energy saving.

[0004] In order to achieve the above purpose, the technical solution adopted by the present invention is: at the lower furnace mouth, a flame guide tube is placed downwardly, the outer diameter of the flame guide tube is consistent with the inner diameter of the lower furnace mouth, the length of the flame guide tube is between 50mm and 200mm, an iron honeycomb briquette spherical gasifier is installed at the lower end of the flame guide tube, and an iron fire collecting hood is installed on the outer periphery of the bottom end of the gasifier. In order to improve the gasification effect, a second flame gasifier is installed on the top of the flame guide tube to perform secondary gasification of the flame. In this way, the gasifier is installed. When the fuel is ignited in the furnace, the flame rushes towards the iron honeycomb briquettes under the influence of the fire collecting hood. The flame enters the honeycomb holes in the gasifier, heats the honeycomb holes, and when the flame gasifier is heated to red, it gasifies the flame and causes it to burn further. The gasified flame rushes to the second iron honeycomb briquettes at the upper end through the fire guide tube and is gasified and burned for the second time. The secondary gasified flame rises from the lower furnace mouth to the bottom of the pot above the upper furnace mouth, releasing heat energy, and is discharged into the atmosphere along the flue and chimney. At this time, the discharged gas is smokeless white gas, which disappears immediately after exiting the chimney, and no smoke can be seen.

[0005] The beneficial effect of the present invention is that it effectively solves the problem of energy waste caused by incomplete and incomplete combustion of fuel in general stoves. Attached Figure 1 illustrate

[0007] Attached Figure 1After the fuel burns in the furnace 8 of the energy-saving coal-wood gasification furnace 9, the flame flows to the honeycomb holes (gasification chamber) in the iron honeycomb briquettes spherical gasifier 2 under the influence of the gas collecting hood 3 to be gasified and burned. The flame then passes through the fire guide tube to reach the second iron honeycomb briquettes spherical gasifier 4 at the top of the fire guide tube 1 for secondary gasification and combustion. The flame then rises to the bottom of the pot at the upper furnace mouth 6 to release heat energy and is discharged into the atmosphere through the flue and chimney 7. Specific implementation plan:

[0008] See attached Figure 1 An iron energy-saving gasifier 9 is manufactured, a flame guide tube 1 is installed at the lower furnace mouth 5, an iron honeycomb briquette spherical flame gasifier 2 is installed at the lower end of the flame guide tube 1, a flame collecting hood 3 is installed on the outer periphery of the lower end of the flame gasifier 2, and a second iron honeycomb briquette flame gasifier 4 is installed at the upper end of the flame guide tube 1. In this way, the energy-saving coal-wood gasifier is installed.

[0009] The above is the specific implementation method of the present invention.
