Abstract

The utility model relates to a horizontal hot water boiler for non-pressure gas, and the horizontal hot water boiler for the non-pressure gas is composed of a boiler furnace body and a burner. The utility model is characterized in that the three-pass structure of an industrial boiler with pressure is adopted by the furnace body, and a cyclone burner with an angle and a bore is adopted by the burner. Owing to the two characteristics, the utility model is that heat exchange area is enlarged by 1/3, the length of flue gas process is enlarged by 2/3, heating power is sufficiently changed, heat loss is reduced, exhaust gas temperature is reduced by 70DEG. C, and heat efficiency reaches more than 80%. The horizontal hot water boiler for the non-pressure gas is an energy saving horizontal boiler which is no in pollution and high in efficiency.

Description

Non-pressure gas horizontal hot water boiler

The utility model relates to a kind of boiler, the horizontal hot-water boiler of particularly a kind of non-pressure gas.

At present, it is coal that the nothing of selling on the market presses horizontal water heater fuel used, inconvenient operation, and labour intensity is big, and has sulfur dioxide to produce contaminated environment in smoke evacuation.

Do not have to press vertical water heater to have to use coal to do fuel, also there are the artificial coal gas that uses of low pollution and natural gas to do fuel, but the flue gas in the vertical heater body of heater be mostly one-way stream to, heat exchange area is little, the thermal efficiency is low, if in order to improve heat exchange area, it is a lot of to cause the furnace space height to increase, and the cost of boiler room increases.

The purpose of this utility model is exactly the problem that exists at the present type of furnace and increasing sharply of housing estate development and needs that the central heating washing is bathed, and provides a kind of non-pressure gas horizontal hot-water boiler.

The purpose of this utility model is achieved in that

The horizontal hot-water boiler of a kind of non-pressure gas is made up of boiler furnace II and burner I;

A. the body of heater II is pressed three return structures of Industrial Boiler for band, its center is a cone type combustion chamber, combustor tail is by logical first spin chamber of seamless pipe, first spin chamber is communicated with the first smoke evacuation deferent, the other end of the first smoke evacuation deferent is communicated with second spin chamber, second spin chamber is communicated with the second smoke evacuation deferent, and the other end of the second smoke evacuation deferent is communicated with afterbody fume collecting chamber, and afterbody fume collecting chamber connects chimney;

B. the burner I is hole, an angle vortex burner, is made up of mixing chamber, combustion gas current divider, air compartment, fuel gas inlet pipe and nozzle; Combustion gas sprays into the combustion gas current divider by the fuel gas inlet pipe by nozzle; Air compartment is communicated with mixing chamber through the hole, angle, and mixing chamber is communicated with the large-scale combustion chamber by quirk.

---described second, third flue is that heat exchanger tube is made up of many seamless pipes of circumferential arrangement.

---there are several to be the aperture of 45 on the described mixing locular wall.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is overall cutaway view of the utility model and embodiment.

Fig. 2 is the cutaway view and the embodiment of combustor component.

Among the figure: 1. chimney; 2. fume collecting chamber; 3. first spin chamber; 4. combustor tail; 5. second smokejack; 6. first smokejack; 7. combustion chamber; 8. second spin chamber; 9. quirk; 11. air compartment; 22. mixing chamber; 33. combustion gas current divider; 44. nozzle; 55. fuel gas inlet pipe.

As shown in Figure 1:

The body of heater II has adopted band to press three return structures patterns of Industrial Boiler; Boiler body II center is a circular cone build large-scale combustion chamber 7, makes the abundant mixed combustion of combustion gas and air.Combustor tail 4 is that this is first backhaul by logical first spin chamber 3 of φ 159mm seamless pipe.It is heat exchanger tube that flue gas changes the first smoke evacuation deferent 6(by first spin chamber 3), this is second backhaul.Flue gas changes the second smoke evacuation deferent 5 by second spin chamber 8, and this is the 3rd backhaul.Passing through chimney 1 to afterbody fume collecting chamber 2 then discharges.

The flue tube that second, third backhaul is flowed through is that heat exchanger tube is made up of many seamless pipes of circumferential arrangement, has increased heat exchange area greatly.

As shown in Figure 2: the burner I adopts hole, angle vortex burner, and it is by mixing chamber 22, combustion gas current divider 33, and air compartment 11, fuel gas inlet pipe 55 and nozzle 44 are formed.

Combustion gas sprays into combustion gas current divider 3 by fuel gas inlet pipe 55 by nozzle 44.

The burner required air is supplied with by air blast, enters mixing chamber 22 through air compartment 11, in mixing chamber, and the combustion gas mixing that air and combustion gas current divider 33 flows out, and enter quirk 9 and burn.

Mixing on the locular wall has several to be the 45 aperture, its objective is to make air along the powerful rotational flow of mixing chamber circumferential edges, mixes thereby reach with the full and uniform of combustion gas.

More than two characteristics are advantage of the present utility model places. Compare with the type of furnace of the same specification of selling in the market, its heat exchange area increases by 1/3, and flue gas flow length increases 2/3, makes heating power be able to abundant exchange, and heat loss greatly reduces. Exhaust gas temperature is 180 ℃ after testing, reduces by 70 ℃ than the vertical boiler of same volume, and the thermal efficiency reaches more than 80%, is pollution-free high-efficient, the Horizontal energy-saving boiler.
