WebMay 5, 2003 · The dP for the control valve is 75 psi (400 - 300 - 25). If you put in a bigger control valve or trim, the pressure drop is still 75 psi across the valve, the larger valve or trim will just operate more closed. Sorry if this is repeating the obvious to you, I'm just not clear what you are asking to be able to comment. WebBoiler feedwater control systems are often the most archaic controls in the steam plant. Poor boiler waterside control contributes to scaling, corrosion, and eventually hot spots and tube failures. The Preferred Feedwater …

WebMar 4, 2024 · There are two common control methods: on-off control and modulating feedwater control. If you use an on-off control, you need a very tough boiler feed pump that can last the wear and tear of sudden water surges. Possible water surges are less of a concern with a modulating feedwater control. 2. Calculate the base flow rate.
