CHAPTER TWO: Boiler Operation Maintenance & Safety

2018-1-19 · 3. Safety Valve: The function of the safety valve is to prevent the increase of steam pressure in the holler above its design pressure. When the pressure increases above design pressure, the valve opens and discharges the steam to the atmosphere. When this pressure falls just below design pressure, the valve closes automatically.

Pressure safety valve theory and PSV valve mechanism

2017-8-23 · One safety valve will be set at the pressure of 200 psi, second at 206 psi (3%) at the drum. Super Heater safety valve pressure will be set at 185.4 (10% 206-20.6) (range 206×10/100) Relieving capacity of drum safety valve should be 75% & Super heater 25% of boiler generation capacity. Interval of periodic inspection
