Abstract

The utility model relates to a vertical combustion boiler with double water jacket, which is designed for raising the thermal efficiency and reducing the energy consumption. The furnace body is composed of an inner water jacket, an outer water jacket and two upper and lower combustion chambers, wherein the inner water jacket is arranged in the lower combustion chamber. The upper combustion chamber is arranged in the inner water jacket. A layer of water surrounds a layer of fire, the layer of fire surrounds the other layer of water, and the other layer of water surrounds the other layer of fire. So the utility model presents the double-layer thermal structure. When the heating surface of the device is enlarged, the heat exchange effect is enhanced. The thermal efficiency reaches to 74.1%. The utility model has the advantages of coal economization, time saving, simple structure, low cost of manufacture, convenient maintenance and use and good effect on eliminating smoke and dust.

Description

Vertical double water jacket burning boiler

The utility model belongs to boiler and makes the field, relates to a kind of vertical double water jacket burning boiler.

In the prior art, the Decree of Patent Office of China a kind of name be called the utility application of the vertical double water jacket normal-pressure boiler of ＂＂, notification number is CN2095337U.This utility model adopts inside and outside water jacket structure, overcome the drawback of traditional vertical normal-pressure boiler extreme misery tubular structure, but, because this utility model is provided with engine firewall between inside and outside water jacket, the differing heights place has at least two holes on inner water jacket wall, be provided with perpendicular, lagging outside between the water jacket upper water,, bring inconvenience to production technology and use maintenance to making this boiler structure comparatively complicated.

The purpose of this utility model is, at above-mentioned deficiency, provides a kind of vertical double water jacket burning boiler, and it not only can improve the thermal efficiency, saves the energy, and simple in structure, making, use, easy to maintenance.

Technical solution of the present utility model is: this stove is made up of body of heater, combustion chamber, fire grate, grey chamber, chimney, filling pipe, feed pipe, blow-off pipe, Pressure gauge, thermometer, safety valve etc., it is characterized in that: body of heater is made up of inside and outside two-tiered water jacket, be provided with two combustion chambers up and down, wherein inner water sleeve wraps in lower combustion chamber, and inner water sleeve is wrapped the combustion chamber; The inner water sleeve lower end connects with outer water jacket by circulating water pipe, upper end and outer water jacket UNICOM; Upper combustion chamber's smoke flue leads directly to fume collecting chamber, and lower combustion chamber's smoke flue is by short smoke pipe and UNICOM of fume collecting chamber, and fume collecting chamber top connects chimney.

Because the utility model can double-deck burn, lower combustion chamber's flame flings the inner water sleeve bottom, then, flue gas is discharged from rising all around, form an annular quirk between inside and outside water jacket, and upper combustion chamber heats to inner water sleeve from interior, this moment, ecto-entad just presented by water jacket bag quirk, quirk bag water jacket, water jacket wrap the double-deck heat collecting structure of quirk again, and to adopt hot side long-pending so increased, reduced the flow resistance of water, strengthened heat exchange effect, test shows, evenly heat efficient reaches 74.1%.The utility model only needs two water jackets, a few root bead pipes, and a fume collecting chamber just can reach the raising thermal efficiency, the effect that cuts down the consumption of energy, compared with prior art, structure, technology are very simple, with low cost, use, easy to maintenance.In addition, itself also has good smoke medicining dust-removing effect this structure, can reduce environmental pollution.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is a schematic appearance of the present utility model.

Fig. 2 is the side cutaway view of Fig. 1.

As can be seen from the figure, body of heater is made up of inner water sleeve 1 and outer water jacket 2, is provided with two combustion chambers in the stove, i.e. upper combustion chamber 3 and lower combustion chamber 4, and wherein inner water sleeves 1 wrap in lower combustion chamber 4, and inner water sleeve 1 is wrapped combustion chamber 3.Inner water sleeve 1 lower end is that circulating water pipe 5 connects with outer water jacket 2 with steel pipe, adopts 12 steel pipes evenly to distribute along garden week, is the 45 welding, upper end and outer water jacket 2 UNICOMs.The flue of upper combustion chamber 3 leads directly to fume collecting chamber 7, and the flue of lower combustion chamber 4 passes through

short smoke pipe

6 and 7 UNICOMs of fume collecting chamber in inside and outside water jacket upper end portion of UNICOM garden ringwise on week, and short smoke pipe 6 adopts 12 steel pipes vertically to weld, the even distribution.Fume collecting chamber 7 is down infundibulate and is located in the water jacket, and top connects chimney 8.For burning, banking fire, the usefulness of poking a fire, establish single-revolution formula damper 9 in chimney 8 bottoms.Be the usefulness of cleaning dust, the UNICOM of relative position with fume collecting chamber 7 has two dedusting holes around upper of furnace body, and deashing valve 10 is housed.

According to the vertical boiler optimum bituminous coal that such scheme is made, under the not too cold situation of load microweather, can only use lower combustion chamber, when the big or temperature of load hangs down, can use two combustion chambers simultaneously, do not use air blast generally speaking, during as the use air blast, be with the damper standard-sized sheet.The utility model is the small heater hot-water boiler, and rated heating capacity is generally within 0.12-0.7MW.
