• Standby Boiler with Delay - Now you can set individual boilers to be either continuously On, Off, or adjusted manually to a specific modulation percent in addition to the Automatic option. In addition to the capability of Standby boiler, the Mini-MOD includes an
2010/5/6 · The higher the pressure setting, the less risk of a pump shutdown that doesn't initiate auto-start. For this system, finding an appropriate value between 43 psig and 102 psig isn't difficult. The recommended value was 78 psig — this allowed some extra range to account for possible pump maintenance practices that might reduce the expected dynamic head at maximum flow.
An 800 HP boiler will need an 80 gpm pump. The next step is to determine the proper discharge of the pump. ASME code requires that you furnish feedwater to your boiler at 3% higher than what the relief valve setting is on the boiler. In addition, you must take
