Steam injectors

Steam injectors heat feedwater by direct steam injection, mixing steam and incoming water inside the injector before the heated water is discharged into the tank. This direct-contact approach helps maintain high feedwater temperature, promotes agitation and supports the release of dissolved gases in atmospheric deaerator duties. Compared with indirect heating arrangements, it can avoid temperature stratification, separate condensate drainage issues and unnecessary secondary steam discharge from external heaters. Steam injectors are therefore often used where users want a simpler way to keep feedtanks hot and ready for continuous boiler feedwater demand. They remain part of the wider feedwater treatment strategy, so downstream chemical deaeration may still be required where application conditions demand it. This makes them relevant for boiler houses that want direct tank heating without adding a more complex external heat exchanger arrangement.
