Abstract
The invention relates to a plate-type gas combustion condensing water boiler using gas as fuel. A burner of the boiler is a plate-type gas burner instead of an original flame burner. A combustion chamber of the boiler is in a smoke-water plate-type heat exchange structure, instead of an original tubular heat exchanger, and the function of condensing steam in smoke is improved for low-temperature water. The plate-type gas burner and a smoke-water plate-type heat exchanger are disposed in the boiler, and heat efficiency of the boiler can be greatly improved. The plate-type gas combustion condensing water boiler is mainly used to produce normal-pressure normal-temperature hot water, heating, living and process hot waters for buildings and the like.
Description
Technical field
The present invention 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 the condensation of water at low temperature to water vapour in flue gas.Owing to being provided with board-like gas burner and cigarette-water plate type heat exchanger in boiler, 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, for heating, life and the technique hot water etc. of building.
Background technology
At present, traditional gas-fired water heating boiler is all made up of burner, combustion chamber, heating clamber three major parts.Boiler-burner adopts fire burner mostly, is by ignited fuel and enough air are provided.Combustion chamber is to be heat by the fuel after lighting and air at this burning conversion, and fire burner there are certain requirements the combustion intensity of combustion chamber, and therefore, the volume of combustion chamber is large.Boiler heating chamber is the heat of high temperature producing in 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 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 flue gas, so boiler efficiency is very low.Burner of the present invention is to adopt board-like gas burner, be combustion gas and air is mixed after by distributor, uniform distribution is on a metal plate that has some apertures, 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, combustion chamber is programmable very little.Heating clamber of the present invention, by tubular type heating arrangement, changes cigarette-water plate-type heat exchange structure into, and the heat transfer coefficient of plate-type heat-exchange is very high, can well carry out condensation to water vapour in flue gas, reclaims a large amount of vapour latent heats in flue gas.The present invention has changed the combustion system of original boiler, can make the volume of combustion chamber reduce, and efficiency of combustion improves.The present invention 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 lower than the dew-point temperature in flue gas, heat exchanger can absorb the latent heat of water vapour in 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 object of this invention is to provide one, adopt board-like gas burner and cigarette-water plate type heat exchanger to engage, board-like fuel gas buring condensation hot water boiler.
The object of the present invention is achieved like this, and board-like fuel gas buring condensation hot water boiler is mainly made up of parts such as air inlet fan, air intlet, fuel gas inlet, air fuel gas premixer, gas distributor, metastable gas pressing plate, porous metals burner plate, combustion chamber, cigarette-water plate type heat exchanger, boiler exhaust gas case, boiler smoke outlet, boiler feed water mouth, boiler delivery port, boiler blow-down water outlets.Air inlet fan is by after air intake and combustion gas mixing, enter air fuel gas premixer and be mixed to form air mixture, air mixture is through gas distributor, enter metastable gas pressing plate, then uniform distribution is lighted on porous metals burner plate surface, air mixture fully produces a large amount of heats after burning in combustion chamber, forms high-temperature flue gas.High-temperature flue gas enters cigarette-water plate type heat exchanger and water heat exchange by combustion chamber, and by the heat transmission feedwater in flue gas, flue-gas temperature is reduced by height.The flue gas reducing after temperature enters boiler exhaust gas case, is discharged out of the furnace by boiler smoke outlet.Water at low temperature, by boiler feed water mouth, enters cigarette-water plate type heat exchanger and high-temperature flue gas and carries out heat exchange, and the temperature of water at low temperature, by low rising, is then sent boiler by boiler delivery port, for user.
Owing to having adopted such scheme, adopt board-like gas burner and the design that cigarette-water plate type heat exchanger engages, be designed to board-like fuel gas buring condensation hot water boiler.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Accompanying drawing is principles of construction figure of the present invention.
1. air inlet fan 2. air intlet 3. fuel gas inlet 4. air fuel gas premixer 5. gas distributor 6. metastable gas pressing plate 7. porous metals burner plate 8. combustion chamber 9. cigarettes-water plate type heat exchanger gas approach 10. boiler delivery port 11. cigarettes-water plate type heat exchanger 12. cigarettes-water plate type heat exchanger exhanst gas outlet 13. boiler exhaust gas case 14. boiler smoke outlet 15. boiler blow-down water outlet 16. boiler feed water mouths in figure
The specific embodiment
In the drawings, air inlet fan 1 is by air intlet 2 by air intake, and the combustion gas with fuel gas inlet 3 enters forms air mixture in air fuel gas premixer 4.Air mixture evenly sprays through gas distributor 5, then does further voltage stabilizing through metastable gas pressing plate 6.Air mixture after 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, after air mixture burning, produces a large amount of heats, forms high-temperature flue gas.High-temperature flue gas, by cigarette-water plate type heat exchanger gas approach 9, enters cigarette-water plate type heat exchanger 11, and in cigarette-water plate type heat exchanger, high-temperature flue gas and water do heat exchange, and the temperature of high-temperature flue gas declines, the temperature rise of water.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 boiler by boiler smoke outlet 14.The condensed water being condensed out, through boiler blow-down water outlet 15, is discharged outside boiler.The water inlet of boiler, by boiler feed water mouth 16, enters cigarette-water plate type heat exchanger 11 and flue gas heat exchange, and in cigarette-water plate type heat exchanger 11, the water that has been enhanced temperature is sent for user by boiler delivery port 10.
