Low pressure steam boilers maintenance | Technical Safety BC

During periods of low steam demand, or when all the use points require pressure-reducing stations, boilers are often operated at substantially less than design pressure. While operating at lower pressure can, in some boilers, provide slightly higher energy efficiency, low-pressure operation also reduces steam ?/p>

Section 23 52 39 - LOW-PRESSURE STEAM BOILERS

The boiler is firing and making steam pressure. The pressure is rising, and the boiler is in low fire due to low load. The operator control will shut down the boiler to prevent too much steam pressure from building up. However, the operator control is not the same as the boiler steam pressure setpoint. These are commonly confused.
