reasons for low steam pressure in boiler operations

For a low pressure boiler <15 psig pressure this if often enough O2 removal for boiler operations. However in a high pressure steam plant 15 psig and above a deaerator is often necessary in order to remove air and noncondensible gases in the feedwater to a level of .007 ppm (7 ppb) or less before it can be introduced to the boiler.

Self-acting Pressure Controls and Applications | Spirax Sarco

Plant operating at low steam pressure - Can tend to reduce the amount of steam produced by the boiler due to the higher enthalpy of evaporation in lower pressure steam. Will reduce the loss of flash steam produced from open vents on condensate collecting tanks.

Lower Pressure Operation of Boiler than Designed ...

Due to increase in superheated steam pressure drop at lower operating pressure and higher steam flow the changes in drum pressure from design will be to a reduced extent. However it will depend on the amount of reduction in operating pressure and the amount of increase in steam flow.

Effect of Low Steam Pressure Operation of Boiler - Bright ...

Many boiler operators prefer to operate the boiler at slightly lower pressure when they have load variation fuel quality variations etc as they get more margins between the safety valve set pressure and the operating pressure. Main steam pressure is used as the input to master pressure controller to change the fuel input to the boiler.
