Definitions

• the invention concerns a heating plant for fuel oil, fuel gas, or other combustible liquids or gaseous materials, according to the introdulement of claim 1.
• the object of the invention is to provide a heating plant according to the introdulement of claim 1, wich shows a better heating economy than nesting plants of this kind belonging to the prior art.
• the heating plant according to the invention is cha racterized by the new combination of aspects indicated in the characterizing part of claim 1. It has surprisingly been found that the heating plant according to the invention shows a considerable better heating economy than plants of this kind belonging to the prior art.
• the heat from the flame is first utilized in normal way by means of one or more heat exchangers, wich are placed in connection with the combustion chamber.
• the flue gas is brought to bubble through the bubble device where the area in which the bubbling takes place makes up a bigger and bigger part of the penetration area the higher the smoke pressure is.
• the washer is the bubble device with water, in this connection, it is crurial to make use of the high effective burner without any form of soot formations at all, if not the bubble device would soon be blocked.
• the bubble device which, is constructed in this way, in a very specially effective way can absorb the condensation heat from the available water vapour, which has originated from the combustion together with the heat found in the flue gas.
• the heat-exchanger which cooles the substantially horizontal part of the dome, is necessary for the heating plant according to the invention, because the substantially horizontal part of the bubble device otherwise would get very hot during operation, and therefore be deformed, whereby there is a big risk for some of the penetrations to be located above the liquid level in the bubble device, thus greatly reducing the effectivity of the heating plant.
• the bubble device is made from metal, preferably stainless steel, which is the normal construction material for the bubble device. Where the bubble device is made from for instance ceramic material, the heat exchanger which cools the substantially horizontal part of the bubble device will not be strictly necessary.
• a specially preferred embodiment of the heating plant in accordance with the invention is characterized by the features indicated in the characterizing part of claim 2. Hereby an especially high heating economy is obtained.
• a specially preferred embodiment of the heating plant in accordance with the invention is characterized by then features indicated in the characterizing part of claim 3.
• an exceptionally effective absorption of the heat content of the flue gas in the smoke washer is obtained, as unwanted pulsations are avoided.
• a specially preferred embodiment of the heating plant in accordance with the invention is characterized by the features indicated in the characterizing part of claim 4.
• a more reliable combustion is obtained without unwanted pulsations, comparred to the cases, in which the penetrations have character of holes.
• this is an exceptionally good embodiment for the manufacture of the bubble device.
• a specially preferred embodiment of the heating plant in accordance with the invention is characterized by the features indicated in the characterizing part of claim 5. Hereby an exceptional high utilization of the heat in the flue gas is obtained.
• a specially preferred embodiment of the heating plant in accordance with the invention is characterized by the features indicated in the characterizing part of claim 6.
• This specially high utilization of the heat in the flue gas can be obtained, because the temperature in the conden sation coil of the heat pump can be brought far below the temperature of the cold run in the other heat exchangers. It is therefore most important that the heat pump is the last heat absorbing device in the heating plant according to the invention.
• the time interval in which the heat pump has to work can for instance be the time interval in which the heating plant works and a certain interval, for instance, two (2) minutes after the heating plant has stopped working.
• the various heat exchangers in the heating plant according to the invention can work separately or in abitrary combinations. However, the heat pump, if such is part of the heating plant, must always work separately.
• a specially preferred embodiment of the heating plant according to the invention is characterized by the features indicated in the characterizing part og claim 7.
• the antipulsation tray must be equipped with ample penetrations for smoke pipes and connection pipes to the heat exchangers, and it has turned out, that the antipulsationtrays produce a suppression of the vibrations in the water mass of the smoke washer, which especially arises at the start of the burner, which again improves the heating economy.
• a specially preferred embodiment of the heating plant according to the invention is characterized by the features indicated in the characterizing part of claim 8.
• the bimetal controlled divertion valve is advantageously constructed in such manner that the divertion valve closes when the burner has been working for about one minute, whereafter full efficiency of the bubble device is obtained.
• an additional improvement of the heating economy is achieved. It appears that the heating plant according to the invention in connection with oil heating can reach an utilization of the heat of the oil of 107 per cent of its lower combustion value, and 110 per cent in connection with gas heating with certain combustible gasses, i.e. natural gas, also calculated from the lowest heating value of these gasses, in both cases even without a heat pump.

• the developped pressure will the flue gas bubble through the penetrations (6) in the skirt all the way round on the bubble device, thus transferring heat and chemical waste products to the water (21).
• the flue gas heat also transfers heat to the exchanger (5).
• the flue gas has left the water and is pushed on, the flue gas is cooled by the heat exchanger (8) whereby the flue gas is condensed and transfers heat to (8), whereafter the flue gas leaves the boiler through the discharge pipe (9) with a low temperature.
• Point (7) is a heat exchanger, which absorbs heat to tap water.
• Point (12) is a neutralisation unit which neutralises the water (21) (if necessary).
• Point (ll) is a heat pump with the aim of cooling the flue gas to almost complete condensation. The hot part of the heat pump is used to preheat the cold tap water (19) to the inlet (15) fro the tap water heat exchanger (7). Also, reference is made to an electronically controlled unit (13), with the aim of controllings start and stop of the heat pump (11) versus the oil burner ( 2 ) in order that they do not oppose each other.
