In order to achieve the above purpose, the basic components of the utility model include: ash drawer, furnace door channel, double-opening furnace door, furnace platform panel, furnace ring, furnace cover, large furnace hole, small furnace hole, chimney casing, chimney , fan, heat dissipation fins, natural air inlet, refractory insulation material, smoke exhaust outlet, furnace, furnace grate.

The shape and size of the ash drawer match the shape and size of the grate, and are used to hold the burned ash. The ash drawer is located under the grate, and the ash drawer There is a certain space gap with the natural air inlet, which is used for natural ventilation and provides part of the air needed for combustion.

As a preference, the double-opening furnace door can be slid left and right on the furnace door channel to adjust the opening degree. When a high fire is required, it is adjusted to the maximum opening position; It is adjusted to a small opening or completely closed to provide air close to the natural air inlet, so as to realize firepower adjustment and reduce unnecessary waste of firewood.

Preferably, the shape of the hearth panel can be rectangle, square, or circle, which is used for placing utensils or serving as a dining table.

As a preference, the large-sized furnace hole is located close to the double-opening furnace door, above the burning firewood, and has strong firepower for cooking and cooking; while the small-sized furnace hole is close to the smoke exhaust outlet, which can Use the waste heat of flue gas to heat domestic hot water, ensure the supply of domestic hot water, and realize energy cascade utilization.

As a preference, the furnace ring and the furnace cover match the shape and size of the large and small furnace holes, and can adapt to pots of different sizes by adjusting the number and size of the furnace rings to meet the requirements of different cooking .

As a preference, use the exhaust heat of the chimney to heat the air in the chimney casing to recover the waste heat from the waste flue gas, and blow the hot air to the room through the fan to realize forced convection heat exchange, The indoor air is repeatedly circulated and heated to make the indoor hot air distribution more uniform and more comfortable.

Preferably, the heat dissipation fins are installed on both sides of the biomass burner, making it a radiator, increasing the heat dissipation area, enhancing radiation heat transfer, and further improving the indoor heating temperature and comfort.

Preferably, the fire-resistant and heat-insulating material is attached to both sides of the furnace to prevent the heat dissipation fins from being scalded due to excessive temperature and improve the safety of use.

The beneficial effect of the utility model is that the structure is simple, economical and practical, convenient for processing and promotion, easy to operate, and meets the cooking needs of the family. Fins, chimney casings, and fans are used to enhance radiation heat transfer and convective heat transfer for indoor heating, improving indoor temperature and heating comfort; efficient cascade utilization of energy can effectively reduce environmental pollutants produced by burning biomass.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described.

According to the embodiment of the present invention, a high-efficiency and energy-saving biomass burning furnace is provided. As shown in Figure 1 and Figure 2, the basic components of the present invention include ash drawer (1), furnace door channel (2), double-opening Furnace door (3), furnace table panel (4), furnace ring (5), furnace cover (6), large furnace hole (7), small furnace hole (8), chimney casing (9), chimney (10 ), fan (11), cooling fins (12), natural air inlet (13), refractory heat insulation material (14), smoke exhaust outlet (15), furnace (16), furnace grate (17).

The shape and size of the ash drawer (1) matches the shape and size of the grate (17), and is used to hold the burned ash, and the ash drawer (1) is located on the grate (17). ), and there is a certain space gap between the ash drawer (1) and the natural air inlet (13) for natural ventilation to provide part of the air required for combustion.

The double-opening furnace door (3) can slide left and right on the furnace door channel (2) to adjust the opening degree, adjust it to the maximum opening position when a large fire is required, and adjust it to the maximum opening position when only a small fire is required or maintain When setting fire, adjust it to a small opening or close it completely, and provide air close to the natural air inlet, so as to realize firepower adjustment and reduce unnecessary waste of firewood.
