Boiler P&ID advice

[u/Revolutionary_Tie551]

Im currently designing a fire tube boiler for a 3rd year project and am now onto drawing my P&ID. ive attached my current design but im unsure if ive missed anything or if i am actually doing it correctly. Any advice would be massively appreciated!

I’d consider a spillback loop around the pump with a backpressure regulator so that you don’t deadhead the pump in the case that your feed water control valve cuts flows back too much. Otherwise, another signal from the level sensor could toggle the pump on and off with a deadband if you don’t want to raise costs as much, but the frequent inrush current to a large motor would be a consideration in that case for your electrical system.
