Boiler Feedwater VFD
Boiler Feedwater VFD
(OP)
Looking at an energy conservation measure. Want to install a VFD on the boiler feedwater pump to maintain a constant pressure regardless of flow rate. Understand that I need a pressure discharge 3% higher than the steam relief valve.
Has anyone done this, any literature or links?
The other idea is to reduce the amount of recirc back to the deairator tank. I can do the thermal calcs to determine min flow to stay below flash point, but does anyone know if there are code minimums, or safety factors I should consider.
