Abstract
The utility model relates to a direct combustion non-pressure hot water boiler which uses fire to directly heat water. The water in the boiler is directly contacted with high-temperature gas which is generated after the burning of the fuel by a spray method. A gas outlet of the combustion chamber is arranged on the bottom of a heating chamber, a sparger is arranged on the top of the heating chamber, a fume exhausting port is arranged on the side upper part of the heating chamber, and a water storing tank is arranged below the heating chamber. The utility model has the advantages of high boiler efficiency and small volume.
Description
The utility model relates to the unpressurized hot water boiler of a kind of fire and water direct contact heat transfer, is used for central air-conditioning and hot water system.
At present, hot-water boiler mainly is based on the waterpipe type structure, the high temperature that fuel combustion produces, by heat-transfer pipe indirect pass to water at low temperature, the temperature of water is improved.In the process of heat of high temperature by tube wall transmission feedwater, its heat transfer coefficient is subjected to pipe wall material, pipe thickness, and the influence of cigarette ash and incrustation scale thickness is very big.Therefore the factor that need consider when boiler design is a lot, and consequently boiler volume is huge, and thermal losses is big, and efficient is low, cost is high.
The purpose of this utility model provides a kind of, and fire directly connects really with water, finishes the unpressurized hot water boiler that heat is transmitted.
The purpose of this utility model is achieved in that fuel oil or combustion gas by burner, finishes full burning in that boiler combustion is indoor.The smokeless gas of burning back high temperature is admitted to heating clamber, and water is done the spray shape by the top of heating clamber and sprayed downwards, and the flue gas of high temperature upwards forms reverse flow with water and conducts heat.After high-temperature flue gas is passed to water with heat, discharge boiler by the blast pipe of upper boiler, there is the boiler bottom in heated water, is extracted out by pump and sends into heating system.
Owing to adopted such scheme, boiler need not heat transfer pipe, and its heat transfer coefficient increases, and boiler volume reduces, and efficient improves.
Below in conjunction with drawings and Examples utility model is further specified.
Accompanying drawing is a sectional structural map of the present utility model.
1. burners, 2. combustion chambers, 3. high-temperature gases export 4. heating clambers, 5. spray throwers, 6. packing layers, 7. exhaust openings, 8. water inlet ball-cock assemblys, 9. flow pipes, 10. ball floats, 11. water tanks, 12. water inlets, 13. delivery ports, 14. boiler bodies among the figure.
In the drawings, burner 1 according to a certain percentage with after air mixes, sprays into combustion chamber 2, ignition with fuel oil or combustion gas.The combustion chamber is a fireproof construction, and purpose is to improve temperature, and fuel is done burning fully at this, forms high-temperature gas.High-temperature gas is by the outlet of the high-temperature gas below the combustion chamber 3, enter heating clamber 4 after, high-temperature gas is upwards motion in heating clamber.Top spray device 5 at heating clamber sprays water at low temperature downwards, directly contacts with high-temperature gas and finishes diabatic process.For increasing the time of contact of water and high-temperature gas, packing layer 6 is set in heating clamber, filler adopts the hollow magnetic tube.Water stops at packing layer in the spray process.After the heat of high-temperature gas was taken away by water, flue gas was discharged by the exhaust opening 7 of heating clamber upper lateral part, and the water that temperature raises exists in the water tank 11.Boiler feed water enters into water ball-cock assembly 8 by water inlet 12, and when water tank 11 outwards supplied water, the water level of water tank descended, under the effect of ball float, ball-cock assembly is opened, and the water that enters ball-cock assembly enters spray thrower 5 along flow pipe 9, the control that how much is subjected to water yield of inflow.Boiler body 14 is containers that communicate with atmosphere by exhaust opening 7, and therefore in the boiler course of work, boiler internal is not have to press.
Claims (3)
1. direct-fired unpressurized hot water boiler, it mainly is made up of burner, combustion chamber, heating clamber, packing layer, spray thrower, water inlet ball-cock assembly, exhaust opening, water tank, it is characterized in that: the gas outlet of combustion chamber is in the bottom of heating clamber, spray thrower is at the top of heating clamber, exhaust opening is at the upper lateral part of heating clamber, and water tank is below heating clamber.
2. according to claim 1, direct-fired unpressurized hot water boiler is characterized in that: the water inlet ball-cock assembly is directly sent water into spray thrower.
3. according to claim 1, direct-fired unpressurized hot water boiler is characterized in that: packing layer is formed with the hollow magnetic tube.
