Description

Gas-fired water heating boiler

The utility model relates to the domestic gas hot-water boiler.

In the prior art, particularly in Chinese patent literature, disclose many kinds of boilers, the vertical boiler of vertical gas fired-boiler and band heat pipe is wherein also arranged.As the CN93206915 patent disclosure be exactly a kind of minitype vertical type gas fired-boiler, it includes drum, lower combustion chamber, burner, fire tube, flue and constitutes.The CN95221149 patent disclosure be the vertical pressure-less boiler of a kind of heat pipe, it includes the water-jacket typ body of heater, heat pipe is embedded in hearth wall, also in burner hearth, be provided with a heat booster, burner hearth is divided into upper and lower two combustion chambers, and on heat booster and its upper and lower combustion chamber, also is provided with the heat pipe formation.Its structure of each prior art constitutes different, and characteristics also have nothing in common with each other, and its oneself advantage and defect is arranged in some aspects.

The purpose of this utility model provides a kind of simple in structure, make easy, the gas and hot water pressure-less boiler that result of use is good.

The utility model includes vertical drum body of heater 1, body of heater lower combustion chamber 2, the gas burner 9 and the smoke discharging pipe in the body of heater that are arranged in the combustion chamber constitute, its major technique is characterised in that, in body of heater 1, be provided with thermal-arrest smoke chamber 3, be provided with the pyrotechnics pipe 4 of some settings in the inner chamber avris branch of thermal- arrest smoke chamber 3 and 2 of combustion chambers and close thermal-arrest smoke chamber 3, corresponding each pyrotechnics pipe 4 of erectting, fixedly connected with thermal-arrest smoke chamber 3 upper walls heat pipe 6 is set, the bottom of heat pipe 6 is passed thermal-arrest smoke chamber 3 and is inserted in the pyrotechnics pipe of erectting 4, is provided with smoke discharging pipe 5 between the upper top of thermal-arrest smoke chamber 3 middle parts and body of heater 1.

The utility model is simple in structure, makes easy.In the body stove on burner 9 burning 2 tops, heating flame chamber diapire the time, flue gas is up to thermal-arrest smoke chamber 3 by the pyrotechnics pipe of erectting 4, is discharged by smoke discharging pipe 5 again, and the lower end of the heat pipe 6 in the pyrotechnics pipe 4 is subjected to high hot flue gas directly to wash away heating, efficiently conduct heat exchange, thermal efficiency height.

Accompanying drawing is the utility model example structure schematic diagram.

The utility model body of heater 1 is vertical drum body of heater, in body of heater 1, be provided with thermal-arrest smoke chamber 3, circumferentially be provided with the pyrotechnics pipe 4 of some settings at 2 inner chamber avris of thermal-arrest smoke chamber 3 and combustion chamber near thermal-arrest smoke chamber 3, corresponding each pyrotechnics pipe 4 of erectting, fixedly connected with thermal-arrest smoke chamber 3 upper walls welding and to be provided with main heat pipe 6, the bottom of heat pipe 6 is passed thermal-arrest smoke chamber 3 and is inserted in the pyrotechnics pipe of erectting 4, be provided with smoke discharging pipe 5 between the upper top of thermal-arrest smoke chamber 3 middle parts and body of heater 1, flue gas flows through pyrotechnics pipe 4, thermal-arrest smoke chamber 3, smoke exhaust pipe 5.

As shown in drawings, the sleeve pipe 7 that also is distributed with some settings in the inboard thermal- arrest smoke chamber 3 and 2 of the combustion chambers of pyrotechnics pipe 4, corresponding each sleeve pipe 7 of erectting, fixedly connected with thermal-arrest smoke chamber 3 upper walls welding and to be provided with auxiliary heat tube 8, the bottom of heat pipe 8 is passed thermal-arrest smoke chamber 3 and is inserted in the sleeve pipe of erectting 7,8 welded closure in the upper end of sleeve pipe 7 and heat pipe are connected, the lower end of sleeve pipe 7 communicates with combustion chamber 2, the heat heating of combustion chamber is directly accepted in the bottom of heat pipe 8 in sleeve pipe 7, conduct heat exchange, further improve the thermal efficiency.
