Mark in figure:
1, fire-sealing ring; 2, stone or metal plate for standing a stove on as a precaution against fire; 3, flue; 4, explosion-proof valve; 5, base; 6, delivery port; 7, return air channel; 8, water jacket; 9, combustion chamber; 10, burner hearth; 11, shell; 12, water return outlet; 13, grate; 14, ash bin.
the specific embodiment:
Below in conjunction with accompanying drawing and preferred embodiment, the energy-conservation air return type water circulation coal heating stove specific embodiment, structure, feature and effect thereof that foundation the present invention is proposed, be described in detail as follows.
Referring to Fig. 1, energy-conservation air return type water circulation coal heating stove of the present invention, comprise flue 3, base 5, combustion chamber 9, burner hearth 10, shell 11, this combustion chamber 9, burner hearth 10 and shell 11 are positioned on base 5, the below of combustion chamber 9 is provided with grate 13, be provided with ash bin 14 in base 5, wherein: the outer wall of described combustion chamber 9 is provided with water jacket 8, and water jacket 8 is provided with delivery port 6 and water return outlet 12 stretches out shell 11; Space between water jacket 8 outer walls and shell 11 inwalls forms return air channel 7; The outer circumference surface of shell 11 is provided with flue 3, is communicated with return air channel 7.Described water jacket 8 is provided with explosion-proof valve 4.The upper end of described shell 11 is provided with stone or metal plate for standing a stove on as a precaution against fire 2.The upper end of described combustion chamber 9 is provided with fire-sealing ring 1.
During use, delivery port 6 on water jacket 8 and water return outlet 12 are connected with radiator or ground heating system, fuel is in burner hearth 10 internal combustion, and the grate 13 of air by base 5 enters burner hearth 10 and carry out combustion-supportingly, and after the fuel combustion in burner hearth 10, heat is by the water in combustion chamber 9 heating water jackets 8; Fuel is after burner hearth 10 internal combustion, the high-temperature flue gas produced carries amount of heat, from the upper end of combustion chamber 9, more descending through return air channel 7, through flue 3, get rid of outdoor, high-temperature flue gas is in the logical 7 descending processes of return air, water from the outer wall heating water jacket 8 of water jacket 8 heats the inside and outside both sides of water jacket 8 simultaneously, and internal layer utilizes burner hearth 10 internal combustion heats heating, the outside utilizes the heat heating of carrying in flue gas, has both improved heat utilization efficiency and the efficiency of heating surface.Water after the interior heating of water jacket 8 from delivery port 6 by the radiator or the ground heating system that are arranged on each room, promote the indoor temperature in each room, realization synchronously heats to each room of whole family, water at low temperature after heat radiation is again in water return outlet 12 enters water jacket 8, recycle, save the energy, improve radiating efficiency.At combustion chamber 9 upper ends fire-sealing rings 1, make high-temperature flue gas rise to stone or metal plate for standing a stove on as a precaution against fire 2 places just descending through return air channel 7, increase the temperature at stone or metal plate for standing a stove on as a precaution against fire 2 places.The present invention is simple in structure, easy to operate, with low cost, practicality handsome in appearance, take full advantage of fume afterheat, furnace body temperature is low, can not cause scald, uses safety, radiating efficiency is high, sufficient combustion, consume energy low, can be at coal resource abundant and city and vast rural area that not yet open piped gas promote the use of.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, any technical solution of the present invention content that do not break away from, any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present invention, all still belong in the scope of technical solution of the present invention.
