Type B Air Ejector is a type of ejector used in steam turbine power plants to remove air and other non-condensable gases from the condenser. The Type B ejector operates by using high-pressure steam to create a vacuum in the condenser, which in turn draws in the air and other gases. This type of ejector is typically used in power plants with a smaller turbine size, where the cost of installing larger, more efficient ejectors is not justified. Type B Air Ejector is less efficient than other types of ejectors, they are still an effective and reliable means of removing non-condensable gases from the condenser and maintaining efficient power plant operation.
