Steam depressurization scheme for exhaust gas analysis
Thread Content
For vapor analysis of exhaust gases, using a DN40 pipe: steam at 0.75 Mpa is to be reduced to 0.1 Mpa – what size throttle orifice plate should be used? Or rather, no matter how large a hole is made in the plug board, this effect can still be achieved. Simpler.
All those I’ve seen are controlled by control valves.
Holes can only limit flow, not pressure; valves are needed
