Gas-operated thermal bath facility is included in induction part below the drum 7, makes the burner of fuel gas buring, in the combustion chamber part of drum 7 inner chamber bottoms and smoke evacuation part on the part of combustion chamber and that be connected with the combustor section branch.Induction part comprises gas combustion apparatus chamber 1, open gas combustion apparatus chamber 1 move door 13, by the control device (not shown) of fuel gas inlet valve 16, filtration, decompression and pressure regulation combustion gas, send into the inlet duct that the steam line 17 of combustion gas is formed, burner comprises the cavum laryngis 14 and the nozzle 15 of mixing air and combustion gas.The combustion chamber part is made up of the combustion chamber 5 of tubular, and an exhaust smoke hole 18 is arranged at the top of combustion chamber 5, and a peephole device 4 is arranged on the nearly lower part wall of combustion chamber 5, is wound with the radiation mozzle 3 of a plurality of inclinations on the outer wall of combustion chamber 5.In the present embodiment, radiation mozzle 3 is fixed by welding on the outer wall of combustion chamber 5.The smoke evacuation part is made up of than the combustion chamber 5 much smaller soaring smoke pipes 8 of one or more tubulose (only illustrating among the figure) the diameter that is connected with combustion chamber 5 by exhaust smoke hole 18, in soaring smoke pipe 8, be provided with the spinning disk 9 that forces flue gas wherein to rise twist, a closable smoke evacuation baffle plate 12 arranged in the top ends of soaring smoke pipe 8.
Drum 7 is inverted U-shaped, in the present embodiment, is storage chamber between the wall of drum 7 and combustion chamber 5 and soaring smoke pipe 8 walls, and promptly water wherein will be heated or be heated into steam.
The boiler heating process of making fuel with combustion gas is described below.
Cold water enters drum 7 by water inlet 2, as be hot-water boiler, then water is full of the storage chamber of whole drum 7, as be steam boiler, then waterline should be controlled on the center line of boiler water gauge (not shown), reserve upper space,, send hot water or steam by delivery port 11 at last as storage that flashes to steam and output region.After the water inlet operation finishes, drop into the igniting preparatory stage, before the ventilation igniting, that opens the smoke evacuation baffle plate 12 of soaring smoke pipe 8 and bottom combustion chamber 1 moves door 13, making the fuel gas buring passage is the gravity-flow ventilation that soaring smoke pipe 8, combustion chamber 5 and gas combustion apparatus chamber 1 form the several seconds up and down, purpose is to exclude last time heating residual waste gas, starts the automatic controller (not shown) then.Open fuel gas inlet valve 16, combustion gas enters cavum laryngis 14 through controlling organization (not shown) such as filtration, decompression, pressure regulation through steam line 17, air is through moving door 13 in cavum laryngis 14 and combustion gas mixing, then enter nozzle 15, automatic controller is controlled the energising igniting immediately, by the flame color that peephole 4 is observed after lighting a fire, adjust combustion gas air inflow or air door, until normal condition.Combustion gas is burnt in combustion chamber 5 by nozzle 15, and the heat of high temperature flue gas that is produced is the heating surface radiant heat transfer around radiation mozzle 3 and combustion chamber 5 immediately.The minute bubbles that water heating back the produces mixing of constantly rising converges to the top delivery port 11 of drum 7 at last.And tiltedly horizontal some radiation mozzles 3 in the middle of burner hearth have certain gradient, can promote the water circulation.Flue gas constantly rises because chimney produces the attraction of pulling out wind and enters in the soaring smoke pipe 8.In soaring smoke pipe 8, because stopping of spinning disk 9, flue gas is forced to rise twist, because the effect of spinning disk 9, the spirality at soaring smoke pipe 8 edges is designed to increase by 3.29 times than straight-through distance apart from length, high-temperature flue gas is fully contacted with the wall of soaring smoke pipe 8 and conduct heat and heat, prolonged exothermic process, increased endothermic effect to stove water.Flue gas drains into outdoor from the smoke evacuation baffle plate 12 that can regulate at last.Owing to can not produce pernicious gas after fuel gas buring is intact, so can not pollute to environment.
The soaring smoke pipe 8 of foregoing description is arranged in the drum 7 of boiler, utilizing flue gas to discharge soaring smoke pipe 8 waste heat before heats boiler water, certainly, soaring smoke pipe 8 in the present embodiment not necessarily is arranged in the drum 7, it also can be connected with combustion chamber 5 and be arranged on outside the boiler, and the waste heat that utilizes flue gas preheats the outer water of boiler or heats.
Describe below with the electric heater unit of electric energy as the energy.As shown in Figure 1, be surrounded with the ring-type radiation mozzle 3 of above-mentioned a plurality of inclinations on the outer wall of combustion chamber 5, its low side is over against the water inlet 2 of drum 7, and its high side is away from water inlet 2.In the storage chamber of drum 7, in the plane of the close combustion chamber 5 of height on combustion chamber 5, the higher side of radiation mozzle 3 be water inlet 2 opposites above insert the water of one to n group heating 6 to drum and/or in the drum from the drum side, the quantity of heating 6 is specifically decided on the capacity of boiler.
Heating 6 is also can be from the top of drum 7 vertical or tilt to insert in the boiler, specifically decides on the boiler type.
The heat release and the endothermic process of the electric heater unit of present embodiment are described below.When needs use the night dip electricity to heat, because it does not need air to mix and the igniting operation, do not need chimney emission yet, as long as close a main switch behind the cutter, can make heating 6 evolutions of heat by automatic control sequence by the automaton (not shown) immediately, transmit the heat heating to boiler water.Because n is organized the top that heating 6 is arranged on water inlet 2 opposites in the drum, cold water is after water inlet 2 enters drum 7, a part directly rises along the drum wall, another part around the drum wall or oblique radiation mozzle 3 rise, and the temperature around the heating 6 is the highest, firing rate is the fastest, a large amount of hot water bubbles that produce conduct heat mutually with cold water on every side, because the bottom of heating 6 is provided with combustion chamber 5, this place's water capacity is reduced, and the upper water volume is bigger, helps the exchange of conducting heat, and forms circulation up and down, because behind the thermal band liter waterborne, following cold water is filled a vacancy immediately from bottom to top, and heated hot water is outwards supplied with from delivery port 11 along the shortest path.
Should be noted that when separately using heating 6 heating boilers,, to the required device of original combustion gas switching position again, as close and move door 13, in the cut-out air is gone into because its characteristic is different with combustion gas; Close smoke evacuation baffle plate 12, do not allow chimney produce and pull out wind.After two was blocked, combustion chamber 5, soaring smoke pipe 8 in the middle of being arranged on all were in the sealing keeping warm mode, can not produce radiation loss, and also favourable water ringing normally moves electrically heated boiler.Otherwise will cause the undesirable phenomenon of ventilation and heat in the boiler electrical heating furnace chamber, this phenomenon also is to cause one of boiler reason of still not having the dual-purpose burning on the same stage of pneumoelectric at present.As for this one-in-and-one-out move door 13 and smoke evacuation the closing of baffle plate 12, still operation automatically by hand, visual boiler capacity size is selected.All operation is better by hand for general microminiature boiler for dual purpose, and middle-size and small-size boiler for dual purpose can adopt air intake to move door 13 manual operations, and smoke evacuation baffle plate 12 is operated automatically, like this, can reduce labor intensity of operating personnel and maloperation.
Through test of many times, the gradient of the radiation mozzle 3 of the foregoing description is being preferably in more than 5 ° about 15 °, and its quantity is about 11 groups, and heating 6 is two or more sets, and the quantity of heating 6 changes with boiler concrete structure and capacity basically.The radiation mozzle 3 that like this, so is provided with forms best water circulation with above-mentioned water inlet 2, delivery port 11, heating 6, combustion chamber 5 and drum 7.
Need to prove that the use of two-purpose heat accumulating gas and electric boiler there is no the branch that uses daytime combustion gas and night to use the strictness of electric energy,, whenever all can use separately that perhaps gas and electricity use simultaneously, to improve heating load as long as need.
The foregoing description only is to illustrate for example, under the situation that does not break away from essence spirit of the present invention and scope, can also carry out various modifications and some part is replaced described embodiment, and these all drop within protection scope of the present invention.
