Abstract
The invention relates to a device for feeding heated water steam via a heat exchanger in a thermal engine and method for using said device.
Claims18
A device for a combustion chamber, comprising a heat exchanger, an exhaust gas supply, a fuel air intake and a water steam source, wherein said heat exchanger
- is a multi-wall tube heat exchanger or a spiral heat exchanger, and
- wherein a hot exhaust gas flow is conveyed from the combustion chamber via the exhaust gas supply and a water-containing medium to be heated is conveyed from the water-steam source into the heat exchanger in separate jacket layers, so that the water-containing medium to be heated is contacted on both sides in each case by a jacket layer containing a hot exhaust gas flow, and
- wherein the fuel air intake is connected to the jacket layer for the water-containing medium to be heated, for the feeding of a water steam-containing, heated, gaseous medium from the heat exchanger into the combustion chamber.
A method for feeding a water steam-containing, gaseous medium via the fuel air intake into the combustion chamber of a heating burner or a thermal engine, comprising the following steps:
- generating a water-containing medium,
- heating of the water-containing medium in a multi-wall tube heat exchanger or a spiral heat exchanger,
- wherein a hot exhaust gas flow and the water-containing medium to be heated are conveyed into the heat exchanger in separate jacket layers, so that the water-containing medium to be heated is contacted on both sides in each case by a jacket layer containing a hot exhaust gas flow without mixing with the respective other medium, and
- wherein the fuel air intake draws off hot water steam from the jacket shell for the water-containing medium to be heated, for the feeding of the water steam, optionally enriched with fuels and/or water, into the combustion chamber.
