Overview
蒸汽喷射器通过直接蒸汽喷射来加热给水，在喷射器内部完成蒸汽与进水混合后，再将加热后的水送入水箱。 这种直接接触式加热方式有助于保持较高的给水温度、增强水箱搅拌效果，并在大气式除氧工况中促进溶解气体释放。 与间接加热布置相比，它可以避免温度分层、独立冷凝水排放问题，以及外置加热器带来的不必要二次蒸汽排放。 因此，当用户希望用更简单的方式让给水箱始终保持高温并随时满足连续锅炉给水需求时，蒸汽喷射器会是常见选择。 它仍然属于更完整给水处理策略的一部分，因此在某些应用条件下，后续仍可能需要药剂化学除氧。 对于希望在不增加更复杂外部换热器的前提下实现直接水箱加热的锅炉房来说，蒸汽喷射器非常适用。
Continue your feedwater heating selection
Steam injectors are usually selected as part of the wider feedwater and heat recovery arrangement rather than as isolated components.
Build the wider feedtank package
Go to feedtanks when the core decision is the wider atmospheric deaerator and storage arrangement around the steam injector.
Combine steam injection with heat recovery
Use heat recovery systems when the project also includes reclaiming flash steam or hot blowdown energy before the feedwater enters the tank.
Connect feedtank heating with condensate return
Review condensate recovery systems when hotter returned condensate and pumping arrangement also affect how the feedtank is heated and supplied.
