At present, the research on biomass briquette fuel stoves just begins, and has more problems, such as unreasonable structure, low heat efficiency and lack of high-quality stoves.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a compact structure is reasonable, and the burning is abundant, and firepower is fierce living beings shaped fuel energy-saving stove.
The utility model discloses a technical scheme is:
a biomass briquette fuel energy-saving furnace comprises a furnace body and a hearth, wherein the hearth is provided with a large-belly opening and a small-belly opening, a secondary air hole is formed in the position above the middle part of the hearth, a feed port of the hearth is of an oblique structure and is connected with the side surface of the lower part of the hearth, the feed port extends out of the furnace body and is provided with a feed door; the bottom of the hearth is connected with a grate, and the grate is provided with a primary air inlet; the hearth is positioned in the hollow middle part of the furnace body, a secondary air channel is formed between the hearth and the hearth cover, an ash chamber is formed between the bottom of the hearth and the bottom wall of the furnace body, an air inlet pipe and an ash outlet are arranged at the position of the ash chamber, and an ash outlet cover is arranged at the ash outlet; the furnace mouth cover at the top of the hearth is provided with a fire-sealing cover with a fire-sealing air hole.
Preferably, the secondary air hole is positioned above the intersection position of the hearth and the feeding hole.
The beneficial effects of the utility model are that fuel is in the furnace bottom, and under the combustion-supporting of wind, the oxygen deficiency precombustion gasification, the gas rises to furnace's first one, under the stirring of overgrate air, intensive mixing, the burning, but the kettle form furnace of abdomen size mouthful little gathers heat and heaies up, improves furnace temperature, favourable burning. The gasification and combustion are integrally completed, the firepower is strong, and the energy-saving and environment-friendly effects are achieved.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
The parts of the drawings are detailed as follows: 1. the secondary combustion area of gas, 2, overgrate air hole, 3, the primary combustion area of gas, 4, secondary wind channel, 5, furnace, 6, precombustion gasification district, 7, air-supply line, 8, grate, 9, ash chamber, 10, primary air import, 11, heat preservation, 12, ash door, 13, feed inlet, 14, feed door, 15, furnace face board, 16, pan bracket, 17, fire door, 18, fire-sealing air hole, 19, fire-sealing cover, 20, furnace cover.
Detailed Description
The invention will be further elucidated and described with reference to the following embodiments and drawings in which:
referring to fig. 1, the utility model comprises a furnace body and a furnace 5, wherein the furnace 5 has a large-belly opening, a secondary air hole 2 is arranged at the position above the middle part of the furnace 5, a feed port 13 of the furnace 5 is of an oblique structure and is connected with the side surface of the lower part of the furnace 5, the secondary air hole 2 is positioned above the intersection position of the furnace 5 and the feed port 13, the feed port 13 extends out of the furnace body, and a feed door 14 is arranged; the bottom of the hearth 5 is connected with a fire grate 8, and the hearth 5 is provided with a primary air inlet 10; the furnace 5 is positioned in the hollow middle part of the furnace body, a secondary air channel 4 is formed between the fire grate 8 and the furnace cover 20, an ash chamber 9 is formed between the bottom of the furnace 5 and the bottom wall of the furnace body, an air inlet pipe 7 and an ash outlet are arranged at the position of the ash chamber, an ash outlet cover 12 is arranged at the ash outlet, and the secondary air channel 4 is communicated with the ash chamber 9 and the air inlet pipe 7; the fire hole 17 at the top of the hearth 5 is covered with a fire-sealing cover 19 with fire-sealing air holes 18, and the periphery and the bottom of the stove are provided with heat-insulating layers 11.
The utility model discloses the during operation is at the during operation, opens earlier fire banking up lid 19, feeding door 14. And an ash discharging door 12 is used for adding fuel and igniting, a feeding door 14 and the ash discharging door 12 are closed, a blower is started, and air is blown into the furnace from the air inlet pipe 7 to support combustion. The fuel is subjected to oxygen-poor pre-combustion gasification in a pre-combustion gasification zone 6 at the bottom of the hearth 5. The generated gas rises to the gas primary combustion area 3 at the upper part of the hearth, the gas secondary combustion area 1 is mixed with the air sprayed by the secondary air holes 2, and the gas is fully combusted, and the pot-shaped hearth 5 with the large belly and the small mouth has the functions of heat gathering and temperature rising, so that the temperature of the hearth can be increased, and the gas is fully combusted. The flame rushes to the bottom of the pot from the fire hole 17, and the reduced fire hole 17 can also increase the scouring force of the flame, which is beneficial to transferring heat to the pot.
