た。Considering the start-up loss time when removing the air inside the condenser body before turbine startup, a large-scale air removal facility is required. In a power plant, both the airtightness and openness are required for the condenser and its peripheral tubing in the process of starting and shutting down, respectively. This is one of the main reasons why it is easy to increase the start-up loss time of the turbine.

置を提案するものである。In order to solve the above-mentioned conventional problems, the present invention has a condenser connected to a condenser turbine, an air removal means connected to an air extraction pipe of the condenser, and a decompression / temperature reduction means. The present invention proposes a decompression device at startup of a condensate turbine, characterized by comprising an auxiliary steam source connected to the steam inflow side of the condensate turbine.

器内を真空にする。After adjusting the low pressure (low temperature) steam or boiler auxiliary steam obtained in the process of boiler ignition / pressurization to a predetermined temperature and pressure through a temperature reduction / decompression device, pass through the crossover pipe or turbine top and then the condenser body Then, the inside of the vessel is made to have a vapor atmosphere of, for example, about 0.10 to 0.15 kg / cm 2 g. Then, the inside is filled with the saturated vapor that has expanded, and the air is pushed out to the outside. After replacing the air in the condenser with steam in this way, the inside of the condenser is evacuated by rapidly reducing the volume by cooling and condensing the steam and suctioning by the air extraction device.

れる。When low-temperature, low-pressure steam is injected into the condenser barrel side space at about atmospheric pressure as described above, the steam volume expands and the inside of the container is replaced with the steam atmosphere in a short time. The air is pushed into the atmosphere through the extraction air pipe so as to surround the condenser cooling pipe nests.

る。Regarding the supply steam, the pressure and temperature inside the exhaust chamber of the low-pressure turbine and the condenser are operating limit values (for example, exhaust chamber temperature <121
As long as the temperature is within the temperature range of ℃ and exhaust pressure <0.30 kg / cm 2 g), air can be fed through the vapor cutoff valve 1 and the pressure reducing valve 2. The steam is cooled and charged from the top of the low-pressure turbine to the condenser barrel side, and advances to the cooling pipe nests as the barrel pressure gradually rises in a mixed state with air. Here, the steam contacts the cooling pipe to become condensate, and the air is pushed by the positive pressure of the surroundings, passes through the air extraction pipe / air discharge pipe, and is discharged into the atmosphere through the check valve 6. When the replacement with steam is completed, the air release ceases, and the steam cools and condenses rapidly to reduce its volume, so that the vessel pressure drops.
Therefore, by simultaneously operating the continuous air removing device at this time, the inside of the condenser can be quickly evacuated.
