Abstract
The utility model discloses a kind of boiler high to the water efficiency of heating surface, relate to boiler technology field.Comprise combustion chamber and hydroecium, bottom and the mouth of delivering coal of described combustion chamber are arranged on outside hydroecium, and other sides of combustion chamber are arranged in hydroecium; The heat energy that combustion chamber produces substantially all is absorbed by hydroecium.By combustion chamber cover within it, the outer surface of helix tube and the outer surface of combustion chamber are provided with fin to described helix tube; Fin, substantially increases the radiating effect of fin, namely improves the heating effect to hydroecium.
Description
Technical field
The utility model relates to boiler technology field, refers to a kind of boiler high to the water efficiency of heating surface especially.
Background technology
At present, the normal-pressure hot-water boiler used in daily life is monolithic construction, primarily of furnace shell, flue, impact tube, horizontal water tube and be built in flue combustion chamber composition, the recirculated water of this boiler is that the retaining room formed between furnace shell with flue from bottom to top and the horizontal water tube communicated with retaining room are circulated, across flue between retaining room and combustion chamber, heat up slowly, combustion chambers burn produce high-temperature flue gas in flue on flowing heating horizontal water tube, directly enter external chimney by impact tube and enter air, the smoke heat energy utilization rate of discharging is low, the flue gas of simultaneously discharging contains large quantity of exhaust gas, to environment.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is that providing a kind of improves boiler firing rate, improves the boiler of smoke heat energy utilization rate.
The utility model provides following technical scheme:
A boiler high to the water efficiency of heating surface, comprises combustion chamber and hydroecium, and bottom and the mouth of delivering coal of described combustion chamber are arranged on outside hydroecium, and other sides of combustion chamber are arranged in hydroecium; The heat energy that combustion chamber produces substantially all is absorbed by hydroecium.The smoke exhaust pipe of combustion chamber is helix tube, and smoke exhaust pipe heats by the high-temperature flue gas that burning produces, and helix tube can increase heating surface area, equally also can increase the heat energy passing to hydroecium.By combustion chamber cover within it, the outer surface of helix tube and the outer surface of combustion chamber are provided with fin to described helix tube, fin comprises base, described base one end is provided with several fins perpendicular to described base, the gully that described two adjacent fin are formed on described base from described base end by dark by shallow, to adapt to the flow tendency of hot-fluid, hot-fluid is when flowing to fin from base, first more shallow gully is run into, what first cause ran into is more shallow gully, hot-fluid can't be hindered to continue a large amount of advance, via the gully of deepening gradually, also reducing gradually of the heat of hot-fluid, the heat that each fin absorbs is impartial, substantially increase the radiating effect of fin, namely improve the heating effect to hydroecium.Described fin two sides are provided with sawtooth, and the cross section of the free end of described fin is circular arc.Add the area of dissipation of fin, substantially increase the radiating effect of fin.

Detailed description of the invention
Below in conjunction with accompanying drawing, a most preferred embodiment of the present utility model is described further, to help understanding content of the present utility model.
As shown in Figure 1 to Figure 3, the utility model comprises combustion chamber 1 and hydroecium 2, and bottom and the mouth 3 of delivering coal of described combustion chamber 1 are arranged on outside hydroecium 2, and other sides of combustion chamber 1 are arranged in hydroecium 2; The heat energy that combustion chamber 1 produces substantially all is absorbed by hydroecium 2.The smoke exhaust pipe 4 of combustion chamber 1 is helix tube, and smoke exhaust pipe 4 heats by the high-temperature flue gas that burning produces, and helix tube can increase heating surface area, equally also can increase the heat energy passing to hydroecium.The outer surface of smoke exhaust pipe 4 and the outer surface of combustion chamber 1 are provided with fin 5, fin 5 comprises base 51, described base 51 one end is provided with several fins 52 perpendicular to described base 51, the gully 53 that described two adjacent fin 52 are formed on described base 51 from described base 51 end by dark by shallow, to adapt to the flow tendency of hot-fluid, hot-fluid is when flowing to fin 52 from base 51, first more shallow gully 53 is run into, what first cause ran into is more shallow gully 53, hot-fluid can't be hindered to continue a large amount of advance, via the gully 53 of deepening gradually, also reducing gradually of the heat of hot-fluid, the heat that each fin 52 absorbs is impartial, substantially increase the radiating effect of fin 5, namely improve the heating effect to hydroecium 2.Described fin 52 two sides are provided with sawtooth 54, and the cross section of the free end of described fin 52 is circular arc 55 shape.Add the area of dissipation of fin 52, substantially increase the radiating effect of fin 5.
