The method, process and technological progress of this programme arrange as follows：
Prepare link：Before being initiated, liquid ethanol is perfused into alcohol vapour generation cavity 10 in ethyl alcohol feedway, until
Height where ethyl alcohol liquid level in entire alcohol vapour generation cavity 10 is higher by height where topmost one layer of the ring disk 14, due to
Ethyl alcohol in equipment running process in alcohol vapour generation cavity 10 is consuming always, therefore is controlled in whole equipment operational process
Ethyl alcohol feedway maintains the ethyl alcohol liquid level in alcohol vapour generation cavity 10 constant always；At the same time ensure original state
Lower water heating chamber 34 is full water expanded state；
Combustion heating link：Natural gas supply pipe 1 and the second combustion-aid air pipe 4 continuously supply naturally to burner 2 respectively
Gas and combustion air start the electronic lighter in heated by natural gas furnace core 22 at this time, and then Flame of Natural Gas jet port 3 produces
The raw flame sprayed upwards, and then the flame sprayed heats the inner wall of heated by natural gas furnace core 22, due to natural gas plus
Hot stove core 22 is metal heat-conducting material, so heated by natural gas furnace core 22 it is heated after continuously to the liquid in alcohol vapour generation cavity 10
Body ethyl alcohol heats, and partial heat is also at the same time conducted to the ring disk 14, and then each the ring disk 14 is in alcohol vapour generation cavity 10
Ethanol liquid be evenly heated；Over time, the temperature in alcohol vapour generation cavity 10 reaches boiling point, Jin Eryi
Ethyl alcohol in alcohol vapor generating cavity 10 comes to life, and the flame for adjusting Flame of Natural Gas jet port 3 sprays intensity, and then makes ethyl alcohol
Ethanol liquid in vapor generating cavity 10 is in low-intensity fluidized state, and the ethyl alcohol in alcohol vapour generation cavity 10 is in boiling process
In continuously generate uniform ethyl alcohol boiling bubble in entire alcohol vapour generation cavity 10, and then ethyl alcohol boils bubble in alcohol vapour
It continuously rolls in generation cavity 10, and whole ethyl alcohol boiling bubble population is in floating trend；Since each the ring disk 14 is by alcohol vapour
Generation cavity 10 has been divided into multiple relatively independent liquid boiling chambers, therefore each liquid boiling chamber can occur relatively solely
Vertical boiling rollover phenomenon, each the ring disk 14 avoid alcohol vapour generation cavity 10 and bulk boiling rollover phenomenon, while the ring disk occur
14, which coordinate it to be evenly distributed with bubble through hole 13 above, can delay bubble floating trend, keep bubble more longlasting in alcohol vapour generation cavity
More lasting rolling, and then the blending and mixing of two kinds of bubbles inside promotion occur in 10, improves alcohol vapour
Stability of the chamber 10 in boiling process；At the same time the second hot-air tracheae 5 was continuously injected to combustion air adapter cavity 11
Combustion air is measured, the compression combustion air in combustion air adapter cavity 11 is through each bubbling stomata on annular chassis 6 at this time
12 are continuously injected into 10 bottom of alcohol vapour generation cavity in the form of tiny bubble, so combustion-supporting bubble population under buoyancy
It continuously floats in alcohol vapour generation cavity 10, since alcohol vapour generation cavity 10 has been in fluidized state, combustion-supporting bubble
In floating-upward process boiling type tumbling motion is done with the liquid ethanol of boiling is in rising trend together；And then alcohol vapour occurs
Alcohol vapour bubble and combustion air bubble in chamber 10 blend under the action of the ethanol liquid of rolling, form a large amount of second
The mixing bubble that alcohol and combustion air height mix；The bubble mixed due to combustion air and alcohol vapour is also in ethyl alcohol
In the boiling liquid of vapor generating cavity 10, it is unable to reach ignition point, but can be promoted by the disturbance of boiling and tumbling effect
Mutually height mixes for combustion air and alcohol vapour, therefore detonation will not occur for the bubble that combustion air and alcohol vapour mix
Phenomenon；The liquid level that the bubble that combustion air and alcohol vapour mix eventually floats up to 10 upper end of alcohol vapour generation cavity is concurrent
Angry follicular rupture, and then the gas that a large amount of combustion airs and alcohol vapour mix continuously enters in burning ring cavity 30；With this
Meanwhile starting the electronic lighter in burning ring cavity 30, since the gas in burning ring cavity 30 is that combustion air and ethyl alcohol steam
The gas of vapour high uniformity mixing, and then the ring cavity 30 that burns generates uniform combustion flame, due on alcohol vapour generation cavity 10
The liquid level at end continuously has the mixed gas of bubbles burst to supplement, thus continuous high-efficient combustion state occurs for the ring cavity 30 that burns, in turn
Flame in burning ring cavity 30 heats furnace core 31 to water simultaneously and heat exchanging water pipe 33 heats simultaneously；It is generated in final burning ring cavity 30
Flue gas enter in the first smoke exhaust pipe 40；At the same time the high-temperature flue gas generated in the combustion chamber 7 of heated by natural gas furnace core 22
It is discharged in the second smoke exhaust pipe 19 by the hard heat exchange smoke pipe 17 being distributed in pencil, and in the hard heat exchange smoke pipe of pencil distribution
17 continuously heat the water in water heating chamber 34.
Water heating path：Cold water is imported into heat exchanging water pipe 33 by cold water inlet 26, then the water in heat exchanging water pipe 33
It is imported into water heating chamber 34 by transition water pipe 28 after being heated, and then the water in water heating chamber 34 is by heat exchange 17 He of smoke pipe
The dual reheating of burning ring cavity 30, is discharged finally by hot water outlet pipe 24；And then realize multi source heating.
The above is only a preferred embodiment of the present invention, it should be pointed out that：For the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
