Safety valve discharge capacity calculation
Thread Content
In the code for pressure vessels, the calculation of safety valve discharge capacity only covers gases, liquids, and saturated steam. What approach should be used when the medium is superheated steam? Furthermore, for an expansion vessel whose inlet is boiler drain water (containing superheated steam), how is the safe discharge volume of the vessel calculated?
Superheated steam should be considered as a gas.
In my opinion, superheated steam should also be calculated as saturated steam, only it is in a supersaturated state; therefore, a slightly higher pressure value is used for pressure release
Superheated steam should be considered as a gas.
