Definitions
- the invention relates to a thermal process based on the water-steam combination process (WDK process) which, with similar efficiency, makes do with compressors and turbines close to production, with concomitant risks being avoided by new designs.
- WDK process water-steam combination process
- 5,537,823 A which combines a gas turbine process (work process) closed clockwise with a gas turbine process (cooling process) closed to the left.Though this can cool well but requires drive power for this purpose, the overall efficiency decreases and the construction costs are increased.
- Saturated steam is available for blade cooling, which improves cooling efficiency.
- the proven series constructions can be used.
- the separation of the mass flow in the direction of compressor and cooling takes place.
- the residual heat remaining from the exhaust gas flow of the hot gas turbine in the compressor path is used completely to reduce the compressor mass flow rate through spray condensate preheating and a bypass which is generated by the temperatures above the condensation temperature of the compressor discharge pressure.
- the resulting cooling mass flow, consisting of bypass and spray quantity relaxes in the cooling path in a close-to-production condensation turbine.
- the subset has a positive effect on the expansion volume and thus on the turbine size.
- another mixing heat exchanger can adapt the turbine inlet temperature for low-pressure expansion by means of condensate injection.
- a pump After liquefaction in the condenser, a pump provides the required bypass pressure.
- the flue gases are still used to preheat the bypass mass flow and the combustion air after steam heating.
- the working fluid-related measures such as filling, venting, dewatering and chemical treatment correspond to the state of the art of the WDK process principle.
- the task is met, close to series constructions from the Turbomachinery can be used.
