The role of steam ejector

The role of steam ejector

The function of the steam ejector is to extract the non-condensable gas and the air leaked into the steam side space of the condenser from the inside of the condenser under negative pressure, so as to maintain the vacuum and thermal performance of the steam side of the condenser.

The working principle of the jet steam extractor

The working principle of the jet steam extractor

The working principle of the steam ejector is that the mixture of non-condensable gas and steam from the steam side space of the condenser is sucked into its mixing chamber by the first-stage steam ejector, and mixed with the high-speed steam emitted from the nozzle in the first-stage mixing chamber. Enter the first-stage diffuser and discharge into the first-stage cooler after compression.

The function of the steam seal extractor is to make the leakage pipeline of the front and rear shaft seals of the steam turbine slightly negative pressure

The function of the steam seal extractor is to make the leakage pipeline of the front and rear shaft seals of the steam turbine slightly negative pressure

The function of the steam seal extractor is to make the leakage pipes of the front and rear shaft seals of the steam turbine slightly negative pressure to prevent the shaft seal steam from leaking from the shaft seal, so as to prevent the leaking steam from entering the lubricating oil and causing the lubricating oil to emulsify.

The shaft seal cooler adopts the form of electric fan

The function of the shaft seal cooler is to make the leakage pipes of the front and rear shaft seals of the steam turbine have a slight negative pressure to prevent the shaft seal steam from leaking from the shaft seal, thereby preventing the leaking steam from entering the lubricating oil and causing the lubricating oil to emulsify.

The role of low pressure heater

The role of low pressure heater

The function of the low-pressure heater is to use the steam that has done part of the work in the steam turbine to heat the condensed water in the heater, increase the temperature of the condensed water, reduce the amount of steam discharged from the steam turbine to the condenser, reduce energy loss, and improve The cycle efficiency of the thermal system.

Working principle of steam condenser

Working principle of steam condenser

The second law of thermodynamics states that heat must spontaneously be transferred from high-temperature objects to low-temperature objects. The steam condenser is a special structure type of surface heat exchanger. It condenses high-temperature steam into liquid through a heat exchange tube as a heat transfer surface. The heat released by the steam is taken away by the cooling medium to complete the heat transfer and the separation of non-condensed gas.
