Definitions
- the invention relates to a Ansaug Kunststofftemperier Nurs, in particular for a gas and steam turbine plant, and a method for operating such a device and in particular relates to an improved peak load operation of a combined cycle power plant.
- the intake air can be cooled by evaporative cooling in front of the gas turbine.
- the effectiveness of this method depends on the humidity and only leads to a limited increase in performance. Also disadvantageous are the associated water requirements or water losses.
- the power penalty due to high ambient temperatures in the gas turbine can be compensated by a heat recovery steam generator auxiliary firing.
- the disadvantages of this solution are the additional production costs, the reduction in efficiency and the oversizing of the water-steam cycle, the steam turbine and, if there is no single-shaft system, the steam turbine generator. Basically, performance losses can of course be compensated by the use of reserve power. Additional gas and steam turbine plant and aggregates, however, lead to high costs with a comparatively short service life.
- the intake air of the gas turbine can be cooled by conventional refrigerators.
- the chillers themselves use a lot of electricity. The process does not lead to a noticeable increase in performance.
- the object of the invention is to improve the peak load operation of a gas turbine plant, in particular a gas and steam turbine plant, so that a high performance is achieved with high efficiency.
- a reservoir for a fluid for heat transfer can be thermally connected to the circuit, the following is achieved:
- a fluid is now made available via the reservoir, with which the temperature of the intake air can be influenced via the already existing intake air preheating system.
- the intake air preheating system can also be used for cooling in the same way as the air is preheated.
- the memory is thermally connectable to the circuit by a first fluid line branches off from the memory and opens into the circuit and a second fluid line branches off the circuit and opens into the memory.
- the fluid is in this case added directly into the intake air preheating system and can influence the temperature of the intake air for a gas turbine via the heat exchanger of the intake air preheating system.
- a heat exchanger is connected in the circuit and connected via a first and a second fluid line to the memory.
- the fluid forms a separate circuit with storage and heat exchanger and the circuit of the intake air preheating remains unchanged.
- the heated by the heat exchange with the intake air fluid may conveniently be cooled again by an air-fluid heat exchanger on the one hand in a storage circuit and on the other hand connected to a branching off of a compressor air line, the storage circuit, the memory, one between the first and the second fluid line connected third fluid line, and portions of the first and second fluid line from the memory to the third fluid line comprises.
- At least one further heat exchanger for cooling the air in the branching off of the compressor air duct in the flow direction of the air is preferably connected upstream of the air-fluid heat exchanger.
- the further heat exchanger can be connected, for example, in the water-steam cycle of a gas and steam turbine plant and used for warming feed water.
- a pressure-reducing valve is advantageously connected between the further heat exchanger and the air-fluid heat exchanger in the air line.
- an air expansion turbine can be connected between the further heat exchanger and the air-fluid heat exchanger in the air line.
- the heat transfer fluid is a mixture of water and cryoprotectant (eg, glycol or ethanol).
- cryoprotectant eg, glycol or ethanol
- the Ansaug Kunststofftemperier beautifully is part of a gas turbine plant or a gas and steam turbine nenstrom.
- a fluid for heat transfer from a memory is emptied and fed to the intake air preheating system for changing the temperature of an intake air.
- compressor air is advantageously used, which itself must first be cooled. It is advantageous if compressed compressor air is cooled in heat exchange with water, for example medium pressure or low pressure feed water of a water-steam cycle of a gas and steam turbine plant.
- a throttle relaxes the cooled compressor air.
- the Storm station and also the Stromerlös least.
- part of the energy generated can now be converted into cold fluid, for example, and stored, which provides additional power output during the day with high electricity revenue.
- the gas and steam turbine plant is similar to a storage power plant, which consumes electricity at low electricity prices and can generate additional electricity at high electricity revenue, without changing the nominal power.
- the cooling of the intake air eg from approx. +40 0 C to +10 0 C, increases the output by 15-20%.
- the technical equipment effort is less than with a solution with conventional refrigeration machines and also the efficiency of the system (in particular with expansion turbine) is significantly higher.
- the intake air preheating system which is usually required in any case, is also used for cooling at high outside temperatures and can therefore be used much more economically.
- the device can significantly reduce the need for auxiliary steam for the so-called anti-icing operation of the gas turbine even in winter or generally at low ambient temperatures by hot water storage, wherein the memory is also discharged via the intake air preheating system.
- a combination of low outside temperatures and high relative humidity values results in a greatly increased risk of icing up the intake system and the entire gas turbine.
- the risks include icing of the filters and the consequent reduction or blocking of the air supply.
- the former leads to reduced performance, the latter indicates standstill of the plant.
- the addition of antifreeze prevents freezing of the water during heat exchange with cold intake air. The required for heating the mixture of water and antifreeze
- Heat is taken, for example, from the steam systems of the water-steam circuit of a gas and steam turbine plant.
- the stored hot water can also significantly increase plant efficiency during part-load operation.
- the heating and cooling of buildings and room units can be done with the help of cold or hot water storage in a simple manner.
- the memory can also be cooled and heated in parallel if necessary.

- a steam flowing through the further heat exchanger 15 heats the circulating fluid and condenses in the process.
- the resulting condensate is removed via the pump 17.
- the heated fluid in turn discharges the absorbed heat in the heat exchanger 12 to the intake air in the intake air line 6.

- valves 24, 25 in the first 20 and the second fluid line 22 are closed.
- a third fluid line 26 connects the first fluid line 20 to the second fluid line 22 and leads via a heat exchanger 27, through which cold air flows on the secondary side.
