In the power industry, in addition to conventional vacuum pumps, Atlas (Yantai) has been dedicated to the development and research of vacuum systems, enhancing their application across various industries. These vacuum systems can improve the thermal efficiency of power plants and offer economical solutions.

Condenser Evacuation

Vacuum pumps and complete sets can be used for two processes in condenser evacuation and vacuum maintenance.

During the evacuation phase, the initial evacuation of the condenser before steam introduction removes air and other non-condensable gases from the condenser. During the vacuum maintenance phase, while the condenser is in operation, the vacuum pump continues to work to remove leaked dry air, maintaining the condenser back pressure at the optimal operating point. This ensures the efficient operation of the turbine and improves the thermal efficiency of the power plant. Optimally selected 2BE and 2BW series liquid ring complete sets can meet users' reliable operation requirements under various complex conditions.

Vacuum Water Suction

In this context, vacuum pumps are utilized to maintain a siphon in the cooling water system of power generation equipment, enabling the cooling water circulation pump to operate at the designed flow rate with minimal power consumption. Liquid ring pumps are an ideal choice for this application.

Flue Gas Desulfurization

During flue gas desulfurization, gypsum slurry is generated, which needs to be dewatered using a vacuum belt filter to produce gypsum products. Some impurities, water vapor, and a small amount of water generated during filtration may enter the vacuum pump. Liquid ring pumps, which use water as the working medium and have significant clearances between components, can effectively operate under these conditions, meeting customer needs and serving as an ideal choice for users.

Fly Ash Conveyance

Fly ash is transported from the dust collector hopper to the central drying collection point using a fluid conveyance method under vacuum. The main advantage of this transfer system is that since the fly ash is conveyed under vacuum, any leakage is accompanied by air intake, and the fly ash does not discharge outward. Liquid ring pumps have the capability to withstand the entry of fly ash into the pump and are the best choice for conveying equipment in such scenarios.

Turbine Seal Tube Exhaust

Steam turbines utilize seal tubes to seal the shaft, preventing air ingress. These seal tubes are sealed using steam. To achieve their design performance, it is necessary to continuously use liquid ring pumps to remove excess steam and condensate.

Vacuum Exhaust

Before boiler water enters the system, it must undergo exhaust treatment, typically carried out using a degassing unit. A vacuum device is placed on the degassing unit, allowing the water to pass through it to remove all dissolved gases before entering the system.

Discharging Geothermal Gas

Similar to condenser exhaust, discharging geothermal gas involves removing air and other non-condensable gases from the steam space of the condenser. However, in geothermal power generation equipment, the steam that drives the turbine comes from the Earth and contains a significant amount of corrosive gases. It is imperative to adopt the most effective methods possible to discharge these gases.
