RE: Direct Injection of Steam

i would say yes. the jet pumps (also known as ejectors) is a good example although the application is not to increase the temp but rather to lift or blend liquids via discharge piping (mixing entrained steam and liquid). drawback - i can think of steam hammer, vibration and excessive noise level if delta p between steam and liquid is excessive. i would suggest injecting the steam into the liquid tru an injection tube to break in into small stream. in this way youll have a uniform mixing and absorption (similar to the way desuperheater and humidifier are made). steam injection devices used for heating are also commercially available.

Subject: [PipingDesign] Direct Injection of Steam

Dear Forum Members

I am familiar with the design of direct injection of steam in an open tank, however, I wish to find out if anyone has had any success in steam injection into a pipe that has a liquid flowing. (In order to heat up the liquid) Is it safe? Is it practised anywhere? What are the pitfalls?
