Definitions
- the invention relates to a heat generator with two burners and one Heat exchanger, the burners supplying the heat exchanger with heat, to heat the liquid flowing through the heat exchanger.
- Heat generators are mainly used in heating devices for heating and the Water heating used, the burner to the required heat output is adjusted. This use of the heat generator normally requires a degree of modulation of e.g. 1: 6. In low energy houses exist lower heat requirements, but there are higher requirements the degree of modulation e.g. 1:10 posed.
- the second burner is there a Stirling burner that heats a Stirling engine and a generator that is in the heat generator with the first burner to generate larger heat outputs is involved. Because both burners are housed in one combustion chamber they can negatively influence each other, especially if if only one of the two burners is in operation.
- the heat exchanger is there only adapted to the heat output of the first burner.
- a second Burner is assigned, which are designed for different heating outputs, and on different sections of the common heat exchanger and / or in different directions these sub-areas act, depending on the heating power requirement the first burner and / or the second burner can be put into operation (are).
- the common heat exchanger can be used individually or together by both burners are supplied with heat, the partial areas of the heat exchanger with their heat transfer surfaces to the different outputs of the two burners are adjusted. Through the optional commissioning of the Both burners will have a much higher degree of modulation in heat output reached.
- the burners are fully shared with the heat generator Integrated heat exchanger, which means not only a robust structure, but also a small space requirement for the heat generator can also be achieved.
- a space-saving heat generator is realized in that the common Heat exchanger with its partial areas directly to the combustion chamber exits of the combustion chamber parts, and in that the exhaust gas outlets the partial areas of the heat exchanger in a common exhaust gas discharge system pass over.
- the adaptation of the common heat exchanger to the different Heat output of the burner is simple in one embodiment possible by using a heat exchanger in the upper area with its heating cables only assigned to the first, more powerful burner is while the lower area of the heat exchanger with its heating cables is assigned to both burners and that all heating cables in series and / or are connected in parallel, or in that the first burner and the second Burner with their flow directions perpendicular to each other on the partial areas of the heat exchanger.
- the heat exchanger and the split combustion chamber can be designed in perform and manufacture in a known manner.
- first burner 10 and a second burner 20 housed in combustion chamber parts 11 and 21 of a single combustion chamber and so decoupled from each other.
- the supply of the gas-air mixture to the Burners 10 and 20 with the control option can be made in a known manner. Since this is not important in the context of the present invention not discussed in more detail.
- Section 30.2 with the smaller one Heat transfer area and with parts of the heating cables 32 is lower Adjusted thermal output of the burner 20. Since the burners 10 and 20 each can be put into operation individually and together according to the power requirement a very large power range with a modulation level that is equal to or can be greater than 1:10.
- the heating cables 31 and 32 are of the one to be heated Liquid flows through and can be connected in series and / or in parallel his.
- the exhaust gas outlets 33 and 34 of the sections 30.1 and 30.2 of the heat exchanger 30 go directly into a common exhaust gas discharge system 40 with exhaust pipe 41 over.
- the only difference between the heat generator according to FIG. 2 and the heat generator is that 1 that instead of a conventional burner 20, a Stirling burner 22 with Stirling engine 23 and generator 24 is used, in addition to Power generation is used.
- the burners 10 and 20 can also in different Directions 15 and 25 to the partial areas 30.1 and 30.2 of the common Heat exchanger 30 act.
- the flow directions 15 and 25 are perpendicular to each other and meet different sizes and thermal outputs the burner 10 and 20 adapted heat transfer surfaces of the Heat exchanger 30.
- the cooled, leaving the heat exchanger 30 Exhaust gas enters a common exhaust gas discharge system 40 with an exhaust pipe 41.
- the thermal outputs of the burners 10 and 20 can be adjusted so that the power range from the smallest adjustable Heating output of the less powerful burner 20 up to the maximum Total heating power of the two burners 10 and 20 is sufficient, which is a very large one Degree of modulation there.
