Mixing of Different Pressure And Temperature steam
Mixing of Different Pressure And Temperature steam
(OP)
I just want to know if there is some reliable system where a low pressure saturated steam (enthalpy-H1 AT p1,t1)can be mixed with high pressure superheated steam (enthalpy H2 at p2,t2)which should result into the the superheated steam (enthalpy-H3 at p2,t3) with same pessure with incresed flow,may be temperature of superheted steam can be lower a bit.in other words
m1H1 @p1,t1 +m2H2 @p2,t2=(m1+m2)H3 @p2,t3
is that possible by some system.if yes how.
thank you
m1H1 @p1,t1 +m2H2 @p2,t2=(m1+m2)H3 @p2,t3

thank you





RE: Mixing of Different Pressure And Temperature steam
This is done with a thermocompressor, where a venturi device like a jet, but non critical is used as a compressor, with the high pressure steam being the motive, and it "compresses" the lower pressure steam up to an intermediate pressure.
Go to www.graham-mfg.com There are others, but they come to mind right off.
Other wise, you would have to use a mechanical vapor compression device, which is a rotating piece of machinery, but, possibly limited, based upon you starting and ending points, (with respect to the physical limitations of the compressor housings).

Saturated steam is already used to desuperheat, by using the saturated steam to atomize the water used for desuperheating, so there is your answer.

Graham has a software(free) that calculates thermocompressor details but the size and parameters are limited.
