- Fig. la shows a device for heating by means of a gaseous medium comprising steam being produced from water, energy for heating the water being provided by burning a fuel, said fuel being a gaseous medium, for example butane, propane, natural gas or the like, or a liquid medium, for example diesel, oil or the like, or a solid medium, for example coal, pellets, peat, oilshale, coke, wood or the like, according to a first embodiment of the present invention.
- the device 1 comprises a container 2, a burner 3 for burning said fuel, e.g.
- the device further comprises an outlet 7, preferably a pipe 7, in the upper part of the pressure chamber 6, and an injection chamber 8 to the inner cavity 8a of which the pipe 7, via a safety valve 9 and a vent passage 10, said valve 9 and passage 10 preferably being located outside of the container 2, is connected.
- the device further comprises an overflow pipe 11 connected to the safety valve 9, said pipe extending down back into the lower part of the container where it is arranged to put out the flame from the burner 3.
- the injection chamber 8 further has an outer cavity 8b surrounding the inner cavity 8a, said chamber 8 being attached to the top of the container 2.
- the device further comprises a flame guard 12, preferably a perforated plate or the like constituting the top of the container 2 and the bottom of the injection chamber 8.
- the steam is intended to be introduced into the inner cavity 8a of the injection chamber 8 via the pipe 7.
- the exhaust gas is intended to be introduced into the outer part 8b of the injection chamber 8 via the flame guard 12.
- the device further comprises a mixing chamber 13 constituting the upper part of the injection chamber, where steam, via openings 13a in the inner part 8a of the injection chamber 8, is intended to be introduced in the outer part 8b of the injection chamber 8, and a steam heating hose 14 connected to the mixing chamber 13 via an opening 17.
- the device further comprises a drainage pipe 15 attached to the lower part of the inner part 8a of the injection chamber 8.
- the device also comprises a valve 16 which is located downstream of valve 10 for extract- ing steam. In order to make the device even more efficient two or more pipe systems 4, preferably helical could be arranged in the container 2.
- Water is introduced via the reducing valve 5 and then reaches the burner 3. It flows in the helical pipe and is pre-heated and then continues to the steam pressure cham- ber 6 where the water starts to boil and reaches a high pressure.
- the steam created continues to the safety valve 9, where the steam goes right through if not, for some reason a stop has occurred. If that is the case an overflow pipe 11 leading down to the burner 3 turns it out.
- the burner 3 is designed in such a way that if the flame goes out a small heat sensor automatically turns off the gas or the corresponding.
- vent passage 10 which functions in such a way that as soon as the steam has entered and reached a certain temperature, at 8 bar it is approximately 180°, it opens automatically and lets the steam pass through. If, by any circumstance, the burner 3 would not react properly the vent passage closes. This is however highly unlikely considering the capacity of the burner 3.
- the pipe coming from the vent passage 10 enters directly into the injection chamber 8, which consists of an inner chamber where the steam is injected and an outer chamber surrounding the inner, where the exhaust gas is introduced. The exhaust gases keep the steam heated already at this stage. The steam rises to the mixing chamber 13, where steam and exhaust gases are mixed.
- the injection cham- ber can as an alternative consist of two hoses having a certain desired length depending on the application, one hose surrounding the other (steam-jacketed) and be injected just before it enters the mixture chamber 8. Condensation can be achieved in such a way that water flows which the steam can carry flowing down in a drainage pipe 15 and further down in the sink. If the burner 3 would go out the water is prevented from rising and flowing in to the burner 3.
- a flame guard designed as a perforated plate, is arranged, as a safety precaution, in such a way that the flames will not be able to rise higher.
- valve 16 located downstream of valve 10 for evacuating steam, so that the device can be used for example for cleaning of tanks for medicine manufacturing, at the end of the cleaning process, when it is desired to get the tank disinfected, by only injecting steam in the tank.
- a two-way valve could be connected to the injection chamber in such a way that the exhaust gas could be evacuated via this valve so that only steam is used in the end of a process as described above. In this way hotter steam can be achieved.
- a steam heating hose 14 connected to the opening 17, provided for transporting the steam and exhaust gas mixture.
- the exhaust gases When the exhaust gases are injected into the steam they are intended for heating up desired cavities whereas the steam in the mixture is intended to loosen up the slag or the like on the surfaces in the cavity.
- the steam As it is mixed with the exhaust gases, prevents from fire due to heating by the exhaust gases.
- the exliaust gases in the mixture When the exliaust gases in the mixture have heated the cavity to the desired operating temperature, the steam in the mixture starts loosening up the slag on the surfaces while at the same time the exliaust gases keep the surfaces heated.
- the exhaust gases transports the steam and keeps it warm in an efficient way. This results in a very high efficiency, with practically no loss of energy.
- Fig. lb shows schematic view of a device 1' for heating by means of a gaseous medium comprising steam according to a second preferred embodiment of the present invention, where the burner is located inside the container at the top.
- the device comprises the same features as the device 1 according to fig. la and functions in the same way. It only differs in that the burner is located at the top.
- lb is that, when operated, the burner 3 of the device is arranged to force the exhaust gas down before it returns and enters the injection chamber 8, which means that the wa- ter/steam in the pipe configuration receives heat from said exhaust gas on its way down in the container 2 and by returning through the container 2 into said injection chamber, which means that the device becomes more efficient.
- Fig. 2 shows a device for heating by means of a gaseous medium comprising steam according to an alternative embodiment of the present invention.
- the device comprises a container 20 having an air inlet 21, a gas inlet 22, a water inlet 23, a steam outlet 24, an exhaust gas outlet 25 and an outlet 26 for the steam and exhaust gas mixture, and a burner 3, for burning a fuel, for example combustion gases, located inside the container 20.
- the burner 3 is intended to be supplied with air through the air inlet 21, preferably from a fan, and with combustible gas such as propane, butane, natural gas or the like through the gas inlet 22.
- the air inlet 21 and the gas inlet 22 are arranged in such a way that the air is mixed with the gas, which is ignited whereby a gas flame appears.
- the water inlet 23 is arranged in such a way that the water fed through the water inlet 23, which preferably is a pipe shaped as a spiral inside the container 20, is heated by means of the burner 3 to steam-generating heat.
- the steam outlet 24 and the exhaust gas outlet 25 are arranged in such a way that they form a common cavity 26 where steam formed from the heated water in the spiral and exhaust gas produced from burning the combustion gases are intended to be mixed and further be introduced into a cavity, such as a ventilating duct, through the outlet 27.
- Fig. 3 shows an example of an application according to the invention, using the device in fig. 2, where the mixture of exhaust gas and steam is introduced from the outlet 27 into the entire length of a channel 30 such as a ventilating duct 30 starting from the bottom and out through the upper part of the ventilating duct 30 by means of automatically heating controlled exhaust valves 31.
- the mixture of exhaust gas and steam heats the inside of the ventilating duct from 10°-90° with a mixture of steam and exhaust gas of 140°-200°, which melts the impurities 32 such as fat and oil deposits 32 on the inside of the ventilation duct 30.
- the melted fat and oil depos- its 32 flows due to their own weight down to the bottom of the ventilating duct to the pipe for runoff of fat and oil to a collecting vessel 33 for fat separation, where fat and oil are cooled and transforms into solid state and can easily be disposed of.
- valve 31 is arranged to be controlled by temperature in such a way that the inner sides of the ventilating duct 30 are supplied with a proper amount of exhaust gas and steam for reaching a temperature for melting the impurities consisting of fat, oils mixed with dust, soot and slag particles, which are stuck on the inner sides of the ventilating duct 30.
- the control of the valve 31 is designed in such a way that the gas and steam mixture is maximally used for the cleaning of the channel regarding supplied energy.
- the exhaust channel can be a ventilating duct such as a kitchen duct, or a chimney or the like.
- the device according to the invention facilitates introducing the mixture into any kind of cavity, where the cavity apart from an exhaust channel can be e.g. a tank; drainage system; chimney; boiler; pipeline; oil container; oil well; oil shale; oilslick or the like.
- the cavity apart from an exhaust channel can be e.g. a tank; drainage system; chimney; boiler; pipeline; oil container; oil well; oil shale; oilslick or the like.
- the device according to the present invention can thus in another application be used for, in a quick, efficient and safe way, removing slag from the inside of the boilers in boiler houses or the like.
- the device can in a further application as mentioned above be used for, in a quick, efficient and safe way, removing fat from the inside of exhaust air ducts such as kitchen ducts or the like.
- the device can in a further application be used for, in a quick and efficient way, removing slag from the inside of channels by food manufacturing such as chocolate channels by chocolate manufacturing or the like.
- food manufacturing such as chocolate channels by chocolate manufacturing or the like.
- the steam and exhaust gas mixture By introducing the steam and exhaust gas mixture into the channel the slag products are liquefied and can be removed.
- the invention can of course be used in any cavity where fat, for example vegetable fat, is present.
- the device can in a further application be used for, in a quick, efficient and safe way, removing soot from the inside of industrial chimneys or the like.
- the top of the chimney is sealed.
- the mixture with a suitable temperature is then introduced. By the heat the soot becomes heavy and falls down, is shoved together and can then easily be removed by transport.
- the device can in a further application be used for, in a quick and efficient way, removing slag from the inside of tanks by medicine manufacturing or the like which is quick and efficient.
- the mixture at preferably 125-140° the slag products are removed and the tank is disinfected and ready for use.
- the exhaust gases are diverted at the end such that only steam is released. This can also be done with a petroleum tank, which then eliminates the risk of fire.
- the device can in a further application be used for, in a quick, efficient and safe way, removing hard paper pulp from the inside of containers by paper pulp manu- facturing or the like.
- the hard paper pulp stuck on walls is loosened up by the heat and can easily be removed such that the container again is ready for use.
- the device can in a further application be used for, in a quick and efficient way, without damaging the pipes, cleaning drainage systems such as cast iron systems or the like in apartment buildings or the like.
- One way of doing this is to attach a pipe tee to the outgoing pipes, presumably located in the basement, then connecting the device for producing the mixture, and then, using the temperature regulator on the roof, introducing the steam and exhaust gas mixture, heating the drainage and consequently the fat without pressure floats down into a collecting barrel or the like.
- the device can in a further application be used for, in a quick and efficient way clearing oil stuck in pipelines.
- the oil stuck in the pipelines is cleared. How big a section of the pipeline that can be cleared depends on the size of the gas burner or the like. Theoretically a section of up to one kilometre could be cleared.
- One way of practically doing this is to use trucks for accessing the pipelines, onto which trucks the mixture device and a water container are arranged.
- the device can in a further application be used for, in a quick and efficient way preventing boring bars to get stuck by drilling in oil wells.
- the boring bars get stuck because of the oil being cooled down due to the thermal rising force from the geo- thermal heat, i.e. hot air, which when moving at high speed gives a cooling effect.
- the device can in a further application be used for in an efficient and power saving way extracting shale oil in shale oil reserves.
- the shale oil lies under ground as bitumen.
- bitumen lies in many cases under natural gas reserves, and thus in these cases by combusting the natural gas, it can then be mixed with steam for producing the steam and exhaust gas mixture. The combustion gas is thus in these cases "free of charge”.
- the device can in a further application be used for in an efficient way collecting the oil from a sunk or sinking oil tanker.
- sinking oil tankers the water is usually so cold that the oil starts sinking to the bottom.
- the device can in a further application be used for in an efficient way collecting the oil from an oilslick.
- the oilslick By covering the oilslick with a blanket or the like, and the introducing the steam and exhaust gas mixture under the blanket and into the oilslick, the oil is heated and becomes more liquid. The temperature of the oil is preserved by the blanket, and thus the liquid oil can easily be sucked up.

- tap water of a temperature of e.g. 6°C is introduced into the arrangement 200 through the pipe 4 and the water is heated to a desired steam temperature and the achieved steam is mixed with the exhaust gases for example in a manner as described above in conjunction with fig. la.
- the mixture is then intro- symbolized into the heat exchanger 51 through the opening 52a, where the fan 53 is arranged to build up a desired pressure of the mixture. Normally the system 50 would also function without the fan 53.
- Water of e.g. 6°C is introduced via the inlet 54 of the heat exchanger, which runs through the pipe 56 to the outlet 55.
- the water in the pipe 56 present within the heat exchanger 51 is heated up by means of the hot mix- ture of exhaust gas and steam, which mixture then at the same time is cooled by the water in the pipe 56 and eventually condenses.
- the condensed mixture flows by means of gravity down through the drainage 58 at the bottom of the heat exchanger, through the condensation pipe 57b and into the pipe configuration 59.

- the pipe configuration In the pipe configuration, light impurities, e.g. C0 2 , which follow the condensed mixture through the condensation pipe 57b to the rises, up through the pipe configuration 59 and are also collected in the collecting vessel 60, and heavy impurities flow down with the water to the water filter 61, e.g. active coal or the like, which collects the heavy impurities.
- the filtered pure water is then introduced into the accumulator tank 62 in order to avoid the system 50 running empty.
- the circulation pump 63 preferably located downstream of the accumulator tank 62, pumps the water back into the device 200, the temperature of the water now being of substantially higher temperature compared to when initially introduced into said device, which consequently means that less energy is required to heat up the water for a second time. The process is then repeated.
