Product description

 

Large capacity steam turbine has large thermal capacity, good thermal insulation performance and long natural cooling time after shutdown. When the metal temperature of the first stage inner wall of the high pressure cylinder is lower than 150 ℃C, the operation of the rolling car and lubricating oil system can be stopped and the maintenance work of the unit will be carried out. In practical operation, the first stage metal temperature of the middle pressure cylinder is about 430C-450 ℃ when the unit is shut down in general accident, and it takes 210h-230h to stop the driving and lubricating oil system when the unit is naturally cooled to 150 ℃. If the sliding parameter is taken down, the minimum metal temperature of the first stage can be reduced to 290 ℃-300 ℃, and the natural cooling down to 150 ℃ to stog the car and lubricating oil system. It still takes 120 hours to 150 hours. Moreover, when the sliding parameter is shut down, the boiler needs a large amount of fuel and increases the fuel consumption of the power plant. After shutdown, the metal temperature in the cylinder decreases from 0.75 ℃ to 1 ℃/h, so that the maintenance period of the unit is prolonged, and the available coefficient of the unit is reduced, and the metal temperature drop rate in the cylinder is between 0.75 ℃ and 1 ℃/h. In order to speed up the cooling rate a steam turbine after shutdown and shorten the cooling time after shutdown, the high and high pressure cylinder of steam turbine is coaled by means of ventilating hot air in the cylinder. In the high temperature stage after the turbine shut down, the working pressure is 0.4 MPA.0.8 MPA and the temperature is about 350 ℃ to dry clean hot air. Gas, and maintain a certain temperature difference with the cylinder wall, from the high-temperature stage of small low gradually adjusted to the low-temperature stage of the large flow of hot air. Through monitoring the change of cylinder stress in the cooling process of steam turbine, it is found that the thermal shock and stress caused by high temperature drying clean hot air is very small, so it is very sate and efficient to use the cylinder fast cooling device to reduce the cylinder temperature, and it is very sate and efficient to use the cylinder fast cooling device to reduce the cylinder temperature. Reliable.After filtering by oil-water filter, the compressed air is heated to a certain temperature by two sets of air electric heaters to be transported to the collector, and then fed into the cooling parts of the steam turbine, in order to facilitate flexible cooperation and control, the air source is transported by the air compressor, which is filtered by the oil-water filter. It's fast cold. The inlet is equipped with control valve, pressure, flow rate, pneumatic cut-oft valve, temperature measuring device to adjust temperature and flow rate at any time, and then cooperate with steam turbine stress monitoring. According to the cooling rate of the cylinder, the temperature of the cylinder can be reduced automatically in the prescribed range, and the safe and reliable fast cooling of the cylinder can be achieved. The emergency repair under the condition of accident has produced great economic benefits in the plan and small repair of the unit.
