CHAPTER TWO: Boiler Operation Maintenance amp; Safety
2018-1-19 · The high pressure feed water is supplied to the boiler through this valve. This valve opens towards the boiler only and feeds the water to the boiler. If the feed water pressure is less than the boiler steam pressure then this valve remains closed and prevents the back flow of steam through the valve.

Cleaver-Brooks - Complete Boiler Room Solutions
2018-8-5 · Determining the proper boiler load is important because when a boiler is oversized for its load, it tends to fire in the lower range (below 50%) where excess air typically is the highest. High excess air causes a 1% loss in efficiency for every 2% increase over the optimal safe oxygen level, which normally occurs in the 80%-and-higher firing range.

Shell Boilers | Spirax Sarco
For any one boiler, if the heat transfer rate (q_dot - body text.jpg) is increased, the maximum allowable boiler pressure is reduced. A compromise is reached with a furnace tube wall thickness of between 18 mm and 20 mm. This translates to a practical pressure limit for shell boilers of around 27 bar.

Special Section: Flow amp; Level: Boiler drum level
2020-4-11 · When there is a decrease in demand, the drum pressure increases and the firing rate changes, thus reducing the volume of the bubbles (i.e., bubbles get smaller). A sudden loss in load could result in high drum pressure causing shrinkage severe enough to trip the boiler on low level. A boiler trip at high firing rates creates a furnace implosion.

NOTE: The air pressure should not exceed 35 psi at high fire. Greater air pressure causes excessive wear of the air pump, increases lute oil usage, and can overload the motor, thus causing damage to the equipment. Abnormally high pressure indicated on the nozzle air pressure is an indication that the burner nozzle has become clogged.
