Describe a preferred embodiment of the present invention with reference to the accompanying drawings in detail.In addition, in the following description, provide the description of understanding necessity of the present invention, so that more in depth understand the present invention.Be noted that for clarity sake, in the following description, omitted unnecessary meeting and made theme of the present invention ambiguous the known function and the detailed description of structure.

As shown in Figure 2, the structure of pumping unit is adopted on the top of a columniform steam generating chamber 10, the bottom of this pumping unit is a pump chamber 8, on the top of this pumping unit is a condensation chamber 5, said steam generating chamber 10 includes one and connects discharge pipe 9 and a smoke pipe 32, wherein forms one by firing chamber 31 of the present invention.As shown in Figure 1, said structure is used for the parallel longitudinal structure more than two-stage, and economizer 2 must exist in multistage pump equipment near, said energy saving device 2 includes a low temperature smoke pipe 33 that promotes waste gas.Shown in the flow chart of Fig. 6, according to the present invention, in filling according to the order water of the arrow shown in the solid line and during outer heat-exchanger (radiator), the air in the equipment is discharged into the outside of equipment by an exhaust port side 24, and each link that circulates all has been full of water.As previously discussed, after equipment and each circulation link all are full of water, at the fuel such as coal gas or oil in case when in firing chamber 31, burning, the calory burning of high temperature at first run to firing chamber 31 around and high temperature smoke pipe 32, thereby in steam generating chamber 10, evaporate the water.The vapor collection of the above generation is arrived the top of pump chamber 8 by steam connection tube 17, by connecting discharge pipe 9 water in the pump chamber 8 is added to steam generating chamber 10 simultaneously, thereby can change the flow direction of the water in the water passage 11, in steam generating chamber 10, store.Therefore, above-mentioned steam is by draining non-return side 12 and draining connecting path 13, arrives discharge water and repeats heating chamber 14-1 and 14-2, is discharged into the outside of equipment by discharge pipe 15 and floss hole 16, the heat energy that in radiator, leaves, and taken out to gravity tank.Subsequent, in the separating surface of collecting a certain amount of steam and water and air in the bottom of interior steam discharge pipe 19 arrives during the bottom of steam discharge pipe 19, the steam that should surpass the hydraulic pressure corresponding with the mobile hydraulic head in the bottom of interior steam discharge pipe 19 is by outer steam discharge pipe 18 and the interior steam discharge pipe 19 instantaneous bottoms that are discharged into condensation chamber 5.

At this moment, when the instantaneous discharging of steam because steam flows fast, and because when steam directly contacts with cold water in a single day rapid condensation taking place will produce fierce vibration and noise, so and a spot of water of discharging together of steam will produce fierce cracked.In order to eliminate above-described cracked sound, the damping of shocks plate 20 of "+" type is installed, and the first de-noising network 21 and the second de-noising network 22 that constitutes the taper network is installed, so that eliminate vibration and the noise that directly contacts generation owing to steam and water.Be condensed into water as the above-mentioned most of water vapor of having eliminated vibration and noise in the bottom of condensation chamber 5, the steam that does not condense has been finished its condensation operation when passing porose separating plate 23, said separating plate is provided with little intensive hole at the center of condensation chamber 5.When the condensation number of steam during greater than the evaporation of water amount, vacuum phenomenon appears in the inside at equipment, produce negative pressure, thus from the water of gravity tank suction successively to the top of suction mouth 1, economizer 2, suction water passage 3, suction water non-return side 4, condensation chamber 5, the bottom that connects water pipe 6, condensation chamber 5, connection suction pipe 7 and pump chamber 8.By repeating following operation continuously: by continuous calory burning produce steam, collect the steam that produces on the top of pump 8, to the instantaneous discharged steam in the bottom of condensation chamber 5, condensing steam is water once more, just can aspirate under the situation of the recycle unit that is not subjected to the external force effect according to equipment of the present invention.

In operation period of the present invention, the air that produces in the inside of equipment is discharged in the air by air vents side 24 during at emissions operation, and the non-return side becomes by negative pressure and produce the suction operation, thereby can prevent that suction from keeping side 24 to carry out.The step that adds hot water is as follows: force in the following order under the current: the suction water reverse side 4 of combuster 31 between suction water route 3 and draining connecting path 13, condensation chamber 5, connect water pipe 6, connect discharge pipe 7, pump chamber 8, connect discharge pipe 9, steam raising chamber 10, the water passage 11 that passage changes, discharge water non-return side 13, and be discharged into the residual steam in the water in condensation process in the air according to the following steps: the condensation/recovery of water makes water rising and mobile simultaneously: steam connection tube 17 in the following order, the top of steam connecting plate 20, the first de-noising network 21, the second de-noising network 22, the bottom of condensation chamber 5, porose separating plate 23, with discharge orifice side 24.In addition, be used for as previously discussed that the equipment of suction and draining is parallel to be equipped with multistagely, thereby can reduce the vibration of link that circulates, and strengthen level and smooth driving.

The difference of reverse burning of the present invention and conventional reverse burning is: the energy that is obtained by the speed of fluid has produced negative pressure, and the front and rear of firing chamber carries out two-way reverse, therefore fuel and air can be in contact with one another 5 times, therefore might realize perfect combustion.

Attempt fuel combination and air to obtain rotating force according to burner of the present invention, allow the first portion's air that produces by blower pass through closure simultaneously, allow 31 the anterior reverse burning of second portion air in the firing chamber, and allow the third part air in the firing chamber burning of 31 rear portion and conventional burner similar.As shown in Figure 1, the first and second part air that enter in the burner insertion opening 25 rotate, fuel burns in firing chamber 31, and repeat to have produced negative pressure between the heating chamber 14-1 at front surface reverse burning plate 29 and front surface discharge water, allow the first and second part air pass the center of front surface reverse burning plate 29 apace simultaneously, suction and the unburnt gas that the inside of steam generating chamber 10 contacts whereby makes great efforts to make it to rekindle with the contact of second portion air and with the second portion air.After this, allow at the third part air of the 3rd air connecting tube 26 and the heating of the 3rd air flue 27 center by a relevant opening 28 and rear surface reverse burning plate 30 fast, thereby repeat to produce negative pressure between the heating chamber 14-2 at rear surface reverse burning plate 30 and rear surface discharge water, whereby suction in the firing chamber collect and the unburnt gas that contact with third part gas in 31 top so that make its perfect combustion.Collect through the above the combusted gas generant cigarette ash that burn on 31 top in the firing chamber, promptly relative lighter non-combustion gas, and it is become burn when reverse under the effect of reverse burning plate.Also have, the combustion gas of perfect combustion are after the high temperature smoke pipe 32 of steam generating chamber 10 and the foot by being connected firing chamber 31 transfers out most of calory burning, all the other heats of discharging from the top of steam generating chamber 10 rise along waste gas rising path 39, bottom at the separating plate 35 that is made of thermoinsulation material descends, and raises once more along the low temperature smoke pipe 33 of economizer 2.After this, successively after pump chamber 8, economizer 2 and condensation chamber 5 transmission after-heats and simultaneously said after-heat descend once more along the space that forms between condensation chamber 5 and economizer 2, by chimney gaseous emission to atmosphere.In other words, the direction that flows of the flow direction of combustion gas and water is opposite, can improve the thermal efficiency whereby, makes it reach best.

From the above obviously as can be seen, the present invention has useful effect: by using a general burner without the change firing unit, employing is according to thermal losses structure of the present invention and combustion method, just can obtain perfect combustion greatly by less heat loss, and under the situation of not using other recycle pump or water pump, just can produce hot water continuously, the hot water that has fundamentally changed prior art whereby produces the implication of equipment or water-heating boiler, and can produce hot water at an easy rate by the most cheap cost.
