Description
Technical field
The utility model relates to a kind of board-like fuel gas buring condensation hot water boiler.It is fuel that this board-like fuel gas buring condensation hot water boiler adopts combustion gas, and the burner of boiler adopts board-like gas burner to replace original fire burner.The heating clamber of boiler adopts cigarette-water plate-type heat exchange structure, replaces the pipe heat exchanger of original boiler, in order to improve water at low temperature to the condensation of water vapour in the flue gas.Owing in boiler, be provided with board-like gas burner and cigarette-water plate type heat exchanger, can greatly improve the thermal efficiency of boiler.This board-like fuel gas buring condensation hot water boiler mainly produces normal pressure, normal temperature hot water, is used for heating, life and the technique hot water etc. of building.
Background technology
At present, traditional gas-fired water heating boiler all is comprised of burner, combustion chamber, heating clamber three major parts.Boiler-burner adopts fire burner mostly, is with ignited fuel and enough air are provided.The combustion chamber is to be heat with the fuel after lighting and air at this burning conversion, and fire burner has certain requirement to the combustion intensity of combustion chamber, and therefore, the volume of combustion chamber is large.Boiler heating chamber is the heat of high temperature that produces in the combustion chambers burn process, passes to water at low temperature the temperature of water is improved.The efficiency of boiler depends primarily on structure and the heating surface area of heating clamber, the heating clamber of existing boiler adopts the tubular type heating arrangement mostly, because the heat transfer coefficient of tubular type heating arrangement is low, and high fume temperature, do not have water vapour condensation in the flue gas, so boiler efficiency is very low.Burner of the present utility model is to adopt board-like gas burner, that combustion gas and air is mixed rear by distributor, uniform distribution is on a metal plate that some apertures are arranged, the burner of even burning is made in igniting, its combustion flame is short, and ignition temperature is high, and combustion intensity is large, therefore, the combustion chamber is programmable very little.Heating clamber of the present utility model changes cigarette-water plate-type heat exchange structure into by the tubular type heating arrangement, and the heat transfer coefficient of plate-type heat-exchange is very high, can well carry out condensation to water vapour in the flue gas, reclaims a large amount of vapour latent heats in flue gas.The utility model has changed the combustion system of original boiler, and the volume of combustion chamber is reduced, and efficiency of combustion improves.The utility model has changed the heating arrangement of original boiler, the exhaust gas temperature of boiler is reduced greatly, make the temperature of cigarette-water plate type heat exchanger be lower than dew-point temperature in the flue gas, heat exchanger can absorb the latent heat of water vapour in the flue gas in a large number, so not only can improve the thermal efficiency of boiler, and also little a lot of of the volume and weight of boiler.
Summary of the invention
The purpose of this utility model provides a kind of, adopts board-like gas burner and cigarette-water plate type heat exchanger to engage, board-like fuel gas buring condensation hot water boiler.
The purpose of this utility model is to realize like this, board-like fuel gas buring condensation hot water boiler is mainly by air inlet fan, air intlet, fuel gas inlet, the air fuel gas premixer, gas distributor, the metastable gas pressing plate, the porous metals burner plate, the combustion chamber, cigarette-water plate type heat exchanger, the boiler exhaust gas case, boiler smoke outlet, the boiler feed water mouth, the boiler delivery port, the parts such as boiler blow-down water outlet form, it is characterized in that: air inlet fan by air intlet with air intake, the combustion gas that enters with fuel gas inlet, in the air fuel gas premixer, form air mixture, air mixture evenly sprays through gas distributor, do further voltage stabilizing through the metastable gas pressing plate again, air mixture is discharged by porous metals burner plate surface after the voltage stabilizing, light on porous metals burner plate surface, air mixture after lighting is burnt in the combustion chamber, form high-temperature flue gas, high-temperature flue gas enters cigarette-water plate type heat exchanger by cigarette-water plate type heat exchanger gas approach, high-temperature flue gas and water are done heat exchange in cigarette-water plate type heat exchanger, the drop in temperature of high-temperature flue gas, the temperature of water rises, reduce the flue gas of temperature by cigarette-water plate type heat exchanger exhanst gas outlet, enter the boiler exhaust gas case, discharged outside the boiler by boiler smoke outlet, the condensed water that is condensed out is through the boiler blow-down water outlet, outside the discharge boiler, the water inlet of boiler is by the boiler feed water mouth, enter cigarette-water plate type heat exchanger and flue gas heat exchange, in cigarette-water plate type heat exchanger, the water that has been enhanced temperature is sent for the user by the boiler delivery port.
Owing to adopted such scheme, adopt board-like gas burner and the design that cigarette-the water plate type heat exchanger engages, be designed to board-like fuel gas buring condensation hot water boiler.
Description of drawings
Below in conjunction with drawings and Examples utility model is further specified.
Accompanying drawing is principles of construction figure of the present utility model.
1. air inlet fans, 2. air intlets, 3. fuel gas inlet, 4. air fuel gas premixers, 5. gas distributors, 6. metastable gas pressing plates, 7. porous metals burner plates, 8. combustion chambers, 9. cigarettes-water plate type heat exchanger gas approach 10. boiler delivery ports 11. cigarettes-water plate type heat exchanger 12. cigarettes-water plate type heat exchanger exhanst gas outlet 13. boiler exhaust gas casees 14. boiler smoke outlets 15. boiler blow-down water outlets 16. boiler feed water mouths among the figure
The specific embodiment
In the drawings, with air intake, the combustion gas with fuel gas inlet 3 enters forms air mixture to air inlet fan 1 in air fuel gas premixer 4 by air intlet 2.Air mixture evenly sprays through gas distributor 5, does further voltage stabilizing through metastable gas pressing plate 6 again.Air mixture after the voltage stabilizing is discharged by porous metals burner plate 7 surfaces, lights on porous metals burner plate surface.Air mixture after lighting is burnt in combustion chamber 8, produces a large amount of heats after the air mixture burning, forms high-temperature flue gas.High-temperature flue gas enters cigarette-water plate type heat exchanger 11 by cigarette-water plate type heat exchanger gas approach 9, and high-temperature flue gas and water are done heat exchange in cigarette-water plate type heat exchanger, the drop in temperature of high-temperature flue gas, and the temperature of water rises.Reduce the flue gas of temperature by cigarette-water plate type heat exchanger exhanst gas outlet 12, enter boiler exhaust gas case 13, discharged outside the boiler by boiler smoke outlet 14.The condensed water that is condensed out is discharged outside the boiler through boiler blow-down water outlet 15.The water inlet of boiler enters cigarette-water plate type heat exchanger 11 and flue gas heat exchange by boiler feed water mouth 16, and in cigarette-water plate type heat exchanger 11, the water that has been enhanced temperature is sent for the user by boiler delivery port 10.
