Abstract
The utility model which relates to an atmospheric hot water boiler comprises a shell of a furnace body, an interlayer, an internal furnace and a furnace body consisting of a flue. The flue is arranged at the head of the ring-shaped internal furnace and the cavity wall of the flue which is close to the head of the ring-shaped internal furnace is provided with orderly arranged pins. The length of the 2 to 5 row pins which are close to the head of the ring-shaped internal furnace is shorter than that of other rows which is far away from the head of the ring-shaped internal furnace, of which form a conical-shaped flue cavity which forms by the ends of pins that extend to the central axis of the flue cavity. The boiler which improves the flue structure based on the former interlayer type tea furnace realizes the aim of increasing the heat efficiency and guarantees the safety usage of the furnace and is long in service life.
Description
The utility model relates to the improvement of hot-water boiler, specifically is a kind of normal-pressure hot-water boiler, and it belongs to the boiler technology field.
The hot-water boiler of prior art has many kinds, and a kind of sandwich-type tea furnace is arranged, and its furnace body is by burner hearth, and flue and interlayer are formed.The thermal efficiency of this boiler is very low.Also have a kind of shell and tube hot-water boiler, its furnace body is by burner hearth, and flue crosses many tubulations and the interlayer flue of flue and forms.The thermal efficiency of this boiler is also lower, and assembles incrustation scale easily in tubulation, deals with improperly to be easy to blast, and causes personal injury accidents.
The purpose of this utility model is that a kind of normal-pressure hot-water boiler will be provided, and this boiler will improve flue structure on the basis of former sandwich-type tea furnace, realize to improve the purpose of the thermal efficiency, and to guarantee safe in utilization, long service life.
Task of the present utility model is finished by following technical scheme, has developed a kind of normal-pressure hot-water boiler, and it comprises by the body of heater shell, interlayer, the furnace body that flue and flue are formed.Described flue is arranged on the ring-type furnace gall head, is arranging orderly pin near being laid with on the flue chamber wall of this furnace gall head.
The pin that the described arrangement of this normal-pressure hot-water boiler is orderly, it is vertically welded on the wall of flue chamber, constitutes the board-like flue of aciculiform.Be shorter than other layer row pin length slightly near this furnace gall head 2-5 layer row's pin length, thereby constitute: stretch to the platform taper flue cavity that the termination of flue chamber central shaft forms by all pins away from this furnace gall head.
The described pin of this normal-pressure hot-water boiler, its radial section or rounded, or ovalize, or triangular in shape, or be quadrangle, or be hexagon and even polygon; Pin length is at 6-50mm, and the pin diameter is: φ 3-26mm.
The described pin of this normal-pressure hot-water boiler, it is laid the zone and is on the wall of flue chamber: the 1/2-2/3 of whole flue chamber wall; Pin length is laid by level Four length, that is: length is differential is 5-18mm, or select one differential, or select two differential, or select three differential; The mutual spacing of all pins is: 10-20mm.
The described flue of this normal-pressure hot-water boiler, its shape of cross section or be rectangle, or be circular, or be ellipse.
Advantage of the present utility model is: owing to arranging orderly pin near being laid with on the flue chamber wall of this furnace gall head, make the flue heat transfer efficiency of this boiler improve widely.Because stretching to the termination of flue chamber central shaft, the orderly all pins of arrangement formed platform taper flue cavity, can guarantee that the flue gas current drainage is smooth and easy, flue gas washes away all pins again and connects solid flue chamber wall simultaneously, make the waste heat of flue gas heat the water in the interlayer, realize improving the purpose of boiler thermal output by two kinds of heat transfer areas of bigger flue chamber wall and all pins surface.
Embodiment accompanying drawings of the present utility model is as follows:
Fig. 1 is the structure vertical view of normal-pressure hot-water boiler.
Fig. 2 is structure master's pseudosection (the A-A view of Fig. 1) of normal-pressure hot-water boiler.
Fig. 3 is all pin laying structure schematic diagrames on the wall of the board-like flue axial of aciculiform chamber.
Referring to the normal-pressure hot-water boiler that Fig. 1-3 makes, it comprises by body of heater shell 1, interlayer 2, the furnace body that flue 3 and flue 4 are formed.This furnace body also has: the water gage mouth of pipe 7, the water-level alarm mouth of pipe 8 is seen fire orifice 9, effluent pipe mouth 10, the feedwater mouth of pipe 11 and end-of-the-pipe 12.Described flue 4 is arranged on the ring-type furnace gall head 5, is arranging orderly pin 6 near being laid with on the flue 4 chamber walls of this furnace gall head 5.
The pin 6 that the described arrangement of this normal-pressure hot-water boiler is orderly, it is vertically welded on the flue 4 chamber walls, constitute the board-like flue 4 of aciculiform, be shorter than other layer row pin 6 length slightly near the 2-5 layer of this furnace gall head 5 row's pin 6 length, thereby constitute away from this furnace gall head 5: by all pins 6 stretch to platform taper flue 4 cavitys 4 that the termination of flue 4 chamber central shafts forms '.
The described pin 6 of this normal-pressure hot-water boiler, its radial section or rounded, or ovalize, or triangular in shape, or be quadrangle, or be hexagon and even polygon; Pin 6 length are at 15-36mm, and pin 6 diameters are: φ 6mm.
The described pin 6 of this normal-pressure hot-water boiler, it is laid the zone and is on flue 4 chamber walls: 2/3 of whole flue 4 chamber walls; Pin 6 length are laid by level Four length, that is: length differential elect as three differential: be 8,7,6mm, promptly pin 6 length are: 6
4=15mm, 6
3=23mm, 6
2=30mm, 6
1=36mm.The mutual spacing of pin is vertical: 12mm, laterally: 13mm.
The described flue 4 of this normal-pressure hot-water boiler, its shape of cross section or be rectangle, or be oval.
