Pilot operated safety valves used on an economizer
- Thread starter MSPVIN
- Start date
There is a detailed discussion in this Pentair document:
The fundamental problem to be addressed here is a water filled economizer that becomes blocked-in while still exposed to hot gasses. Tube rupture can occur.
Basically, the safety relief valve must be sized for a specific massflow in both steam and water.
The rated capacity of these safety relief valves is determined by the economizer manufacturer based upon the maximum heat absorption rate.
Hope that this helps .....
