Description

Multifunctional coal gasification energy-saving furnace

The utility model relates to a civil multi-functional firewood gasification energy-saving furnace.

At present, the stoves used by people generally have many problems such as low heat utilization rate, single function and single fuel, and insufficient fuel combustion.

The purpose of this utility model is to overcome the defects of the existing stoves and provide an energy-saving stove that integrates cooking, heating, washing and bathing and can burn coal, firewood, sawdust and other fuels.

The utility model is characterized in that: the furnace body is placed in a cylindrical water tank, the furnace has a double-layer structure, there are three exhaust holes on the top of the furnace, a secondary air intake channel is formed between the inner and outer tanks, and the lower part is provided with a secondary air inlet. There is a fire cover on the air hole and the furnace mouth; there is a water jacket on the furnace mouth, and there are two interfaces connected to the heating pipe on the water jacket; there is a flue gas outlet between the water jacket and the stove mouth; the stove mouth has three activities. Fire-shielding cover; there is a drawer-type air door under the furnace, which can store and clear the furnace slag.

When the utility model is made, the large and small specifications are determined as required, and the materials include metal sheets, cast iron parts, heat insulating materials and the like. As shown in Figure 1, the furnace body is placed in a cylindrical water tank, and the joints are sealed and welded. The bottom of the water tank is the water inlet pipe interface, and the upper part is the water outlet pipe interface; the inner and outer furnaces can be made of cast iron or ceramics, and the interlayer distance between the inner and outer inner tanks is 10. mm; the specifications of the inner and outer tanks depend on the needs, and three rows of air holes of Φ2-3 mm are arranged on the upper end of the inner tank; there are secondary air inlet holes on the grate between the inner and outer tanks, and the total area of the holes should be slightly larger than The total area of the upper stomata. The fire sealing cover at the furnace mouth is cast iron. The water jacket is cast iron, the outer and lower parts are flat, the inner and upper parts are blade-shaped to fully absorb heat, the inner diameter of the water jacket should be equal to the inner diameter of the furnace liner, and the height is preferably 100 mm. There are two pipe connections on one side of the water jacket (see Figure 2). There is a flue gas outlet between the water jacket and the stove mouth; there are three movable fire shields at the stove mouth, and the fire shields are cast iron. There is a bucket-type air volume adjustment door under the grate. The wind divides itself in the air chamber under the grate. Furnace gall and furnace body, between the stove body and the water tank are filled with heat insulating material. The water tank and the furnace body are generally made of 3 mm steel plates, and the furnace body can be made of 0.5-1.0 mm metal plates, or bricks and cement.

The cooking range made by the utility model has a heat utilization rate higher than that of a common cooking range by more than 30%, a large water tank, automatic water supply, 24-hour hot water supply, and hot water shower for 3 people. The water in the water jacket heats up quickly, and the heating effect is good. And it can burn various fuels such as coal, firewood, charcoal, sawdust, etc., the combustion is sufficient, smokeless, clean and hygienic.

Describe below in conjunction with accompanying drawing:

Fig. 1 is the structural representation of the utility model. Among them: 1 water tank, 2 furnace body, 3 furnace mouth, 4 heating water jacket, 5 three exhaust holes on the upper end of the inner tank, 6 fire sealing cover, 7 flue gas outlet (outside connected to the chimney), 8, 9, 10 activities Fire shield, 11 stove body, 12 water outlet pipe joint, 13 furnace leg, 14, 20 heat insulation material, 15 outer furnace liner, 16 secondary air intake channel, 17 secondary air intake hole, 18 drawer type air volume adjustment door, 19 Inner furnace liner, 21 furnace grate, 22 water tank inlet port
