Calculation of the discharge capacity of the safety valve at the outlet of a plate heat exchanger
Thread Content
Dear all, we need to calculate the discharge capacity of the safety valve on the cooling water outlet side of a plate heat exchanger. Could someone please tell us how to do this? Are there any examples we can refer to? Is it something like the expansion volume minus the normal volume, or something else? Please advise.:handshake :handshake
For your specific operating conditions, you can refer to section 7.0.1.3 of \"HG/T 20570.2-95 Installation and Selection of Safety Valves\": when the inlet and outlet valves on the cold side of the heat exchanger are closed, the discharge volume is calculated based on the heat input during normal operation. The calculation formula is given in equation (7.0.1): V = B·H / (G1·CP), where V represents the volume discharge rate in m3/h; B is the coefficient of volume expansion in l/℃; H is the maximum heat transfer rate under normal operating conditions in kJ/h; G1 is the density of the liquid phase in kg/m3; and CP is the specific heat at constant pressure in kJ/(kg·℃). This information is provided for your reference.
Hmm. That’s right. I found it later. There was no way to delete the post, haha. Thanks anyway to the person who posted above.:lol :lol :lol
