Definitions
- the invention relates to a heat exchanger for heating, in particular, organic heat transfer media with the aid of combustion gases, consisting of a housing with a jacket, base and cover and at least one pipe register accommodated in the housing, the housing having thermal protection and an inlet and an outlet for the combustion exhaust gases.
- the flue gases can be generated in a separate combustion chamber or with a burner installed on the floor.
- the jacket has a reinforcement or lining made of ceramic material, for example, brick, refractory bricks as heat protection.
- ceramic material for example, brick, refractory bricks
- an organic heat transfer medium such as a thermal oil
- the object of the invention is to avoid undesired reheating of the heat transfer medium after switching off the system having the heat exchanger.
- cooling systems through which a cooling medium flows, at least in regions, on the outside of the jacket, the bottom and the cover, e.g. welded full pipes, cooling jackets or half pipes are arranged, which are attached with their free edges to the relevant components.
- this invention achieves a 100% containment of the flame with cooled surfaces and thus a lower flame temperature compared to conventional combustion chamber designs. This avoids the environmentally harmful nitrogen oxide pollution associated with higher combustion temperatures.
- the cooling systems with their free edges on the assigned components, i.e.
- the jacket, cover and base are welded, in particular on the cover and base, they can be laid in a meandering shape, but also spirally. Otherwise, a version is recommended in which the half-tubes are laid on the jacket as a spiral surrounding the jacket. This arrangement can also be varied with regard to different thermal loads on the individual housing parts in that the half-tubes are laid on the jacket as a spiral with a variable pitch.
- the spiral will be installed with a small pitch in areas with high thermal loads and the spiral with a larger pitch in areas with lower thermal loads.
- Versions with burner arrangement or flue gas inlet in the floor and concentrically arranged coils are characterized in that the combustion gases are deflected in the area of the cover. The flue gases then flow through the annular gaps formed by the coils and the cooled jacket to the round gas outlet. Since the greatest heat load on the jacket of the heat exchanger takes place in the area of the flue gas deflection, the spiral of the cooling pipes near the cover should have the smallest slope. The remaining areas of the jacket need to be cooled less, in particular cooling in the jacket area without an annular space can be dispensed with, because here the cooling is carried out by the pipe coil lying on the inside of the jacket.
- the heat exchanger shown is used to heat organic heat transfer media in particular with the aid of combustion exhaust gases. It exists in its basic structure of a cylindrical steel jacket 1, which is closed at both ends by a cover 2 and a bottom 3.
- a pipe register 5 is arranged, which consists of a spirally arranged pipe coil, the individual turns 6 of which are arranged close to one another and close to the inside of the jacket 1.
- the pipe register has in the area of the bottom 3 the inlet connector 7 and extends to shortly before the cover 2.
- the turns 6 merge into the turns 8 of a second pipe register 9, which is concentric with the first pipe register and around it also with close to one another lying turns 8 is arranged.
- the second pipe register 9 ends at an outlet connection 15.
- the jacket extension 12 extends from the cover 2 to approximately half the length of the jacket 1 and is connected to the jacket 1 via a radial flange 14.
- an outlet connection 10 for the combustion exhaust gases is connected to the annular space 13.
- the combustion exhaust gases consequently flow from the inlet connection 4 in the base 3 to the cover 2, where they are deflected into the annular space 13, which they leave through the outlet connection 10.
- the annular space is delimited on the inside by the tightly lying turns 6 of the tube register 5.
- the bottom 3 has inlet ports 4 for combustion gases of a burner, not shown.
- cooling tubes are laid on the outside on cover 2 and base 3. These are half-tubes 16 which are welded with their free edges to the outside of cover 2 or base 3.
- the half pipes 16 are laid in the form of meanders on the cover 2 and the bottom 3.
- At the ends of the cooling coil there are connecting pieces 17 and 18, respectively, via which the cooling medium can be supplied or removed.
- the jacket extension 12 also has a cooling coil on the outside in the form of a spiral made from half-tubes 19, which are welded with their free edges to the outside of the jacket extension 12.
- the spiral has an uneven slope.
- the slope in the lid area is small because the heat load is greatest there due to the deflection of the combustion exhaust gases.
- the slope of the spiral becomes increasingly larger in the direction of the radial flange 14.
- This spiral cooling coil also has connecting pieces 20, 21 through which a corresponding cooling medium can flow in or out.
- the cooling coils formed by the half pipes 16 and 19 are to be flowed through by the organic heat transfer medium, which also flows through the pipe registers 5 and 9.
- the organic heat transfer medium also flows through the pipe registers 5 and 9.
- circuits can be realized in which the heat transfer medium flows first through the tube register 5 and 9 and then through the cooling coils formed by the half tubes 16 and 19 or vice versa.
