Description

Domestic energy-saving hot water boiler

The utility model relates to a kind of family life multifunctional and energy-saving hot-water boiler.

The existing family life energy using technology of China mostly is traditional stove and fiery pit, and the thermal efficiency only reaches 20-25%.In the last few years, along with the household heater rise of (claiming native heating installation again), develop many novel native heating boilers, its structure mostly is coiled, and pipe-support type and jacket type etc. are in order to utilize smoke exhaust heat in the chimney, what have links to each other the body of heater chuck with the chimney chuck, though heat energy utilizes to some extent, the thermal efficiency is still very low, only reaches 40-50%.What its function had can only make heating one usefulness, and what have does heating and cook dual-purpose.Because only on stove body and chimney, can't satisfy the restriction of heat exchange area, quantity of heat production is little, and the heating of very little living space can only be provided, and is little because of combustion space again, it is dangerous to burn, over-emitting black exhaust, it is not enough to add heat exchange area again, causes the exhaust gas temperature height, heat loss is big, the thermal efficiency is low, has wasted fuel and steel, has polluted environment.

The purpose of this utility model provides a kind of family life multifunctional and energy-saving hot-water boiler, and it can reduce exhaust gas temperature, reduces every heat loss, and the thermal efficiency is up to 70-75%, and pollution abatement, and the hydromining of heat supply simultaneously warms up, heats water and cooks three usefulness.

Design of the present utility model is as follows: in a chuck housing 1, two burner hearths 2 and two flues 3 have been arranged, in two flues, arranged the tube bank 4 of the in-line arrangement (or fork row) of flue gas transversal flow again, arrange the heating tube 6 that is connected with the outer heating water tank 5 of body of heater in first flue, burner hearth bottom is established fixed grate 7, two burners 8 are established on top and 9 and two flue bottoms of two exhanst gas outlets (trunnion) are provided with dust deposit in flue shoot door 12, and chimney 13 is located at the afterbody of flue.Be provided with a burner hearth intercommunicating pore 14 in the middle of two burner hearths.Scribble a kind of new magnesium silicate insulating material in chuck housing 1 outside.According to the needs of design of heating system, can offer hot water outlet at the scene, top of body of heater and offer the backwater base, so that be connected with heating system with the base and the bottom of furnace body of expansion tank expansion tube.

Advantage of the present utility model: more energy-conservation 50% than traditional stove under the prerequisite of three usefulness, usefulness the heating chuck hot-water boiler or the dual-purpose chuck hot-water boiler energy-saving efficiency raising 30-20% that make than at present domestic prepattern still; This utility model can reduce exhaust gas temperature, reduces every heat loss, and the thermal efficiency is up to 70-75%, and pollution abatement, for exploitation family life boiler has been opened up wide approach.

Fig. 1 is a main pseudosection of the present utility model.

Fig. 2 is a side cutaway view of the present utility model.

Fig. 3 is the profile of Fig. 2 along A-A.

Wherein: 1, chuck housing 2, burner hearth 3, flue 4, tube bank 5, water tank 6, heating tube 7, fire bars 8, burner 9, trunnion 10, flashboard 11, clean-out door 12, dust deposit in flue shoot door 13, chimney 14, burner hearth intercommunicating pore

In the rectangle chuck housing 1 that the utility model sheet metal is combined into, two burner hearths 2 and two vertical gas passes 3 have been arranged, in two burner hearths 2, have a burner hearth intercommunicating pore 14, three comb bundles 4 in first vertical gas pass, have been arranged, in second vertical gas pass, five comb bundles 4 have been arranged on the perpendicular direction, four comb bundles 4 on transverse direction, have been arranged, 20 tube banks 4 have been arranged altogether, also arrange the heating tube 6 that is connected with the outer heating water tank 5 of body of heater in first vertical gas pass, burner hearth bottom is established fixed grate 7, two burners 8 and 9 and two flashboards 10 of two exhanst gas outlets (trunnion) are established in top, furnace bottom is provided with clean-out door 11, two flue bottoms are provided with dust deposit in flue slag door 12, and chimney 13 is located at the afterbody of flue, the chuck housing 1 outer magnesium silicate heat-insulation and heat-preservation material that scribbles.

Fuel adds burning from burner during use, combustion gas is radiation heat transfer in burner hearth at first, cook through burner heating pot and stove, changeing 90 ° then enters first vertical gas pass by trunnion 9 and carries out the heat convection first time, change 180 ° from this flue bottom and enter second vertical gas pass, enter chimney behind the heat convection for the second time, be discharged into atmosphere.Water is connected water filling from the expansion tank adding or with body of heater and running water pipe, is subjected to the water of the high side of cigarette temperature to do ascending motion in stove, is subjected to the water of cigarette temperature downside to do descending motion, and so circulation repeatedly in stove supplies heating usefulness with the water heating.

Claims (3)

1, a kind of family life multifunctional and energy-saving hot-water boiler of forming by chuck housing 1, burner hearth 2, flue 3, water tank 5, fire bars 7, burner 8, clean-out door 11, dust deposit in flue slag door 12 and chimney 13, it is characterized in that in chuck housing 1, having arranged two burner hearths 2 and two vertical gas passes 3, in two flues, arranged the tube bank 4 of the in-line arrangement (or fork row) of flue gas transversal flow again, also arrange the heating tube 6 that is connected with the outer heating water tank 5 of body of heater in first flue, upper furnace is established i.e. (trunnion) 9 and two flashboards 10 of 8, two exhanst gas outlets of two burners.
