Difference Between MAWP and Design Pressure

Steam boilers are typically larger pressure vessels capable of providing energy to industrial operations. They accomplish this by boiling water at subcritical pressures with intricate fuel systems. In some jurisdictions, the high pressure and high steam output capability of steam boilers requires a fully certified and licensed operator to be on-site in order to be operated.

Controlling Boiler Water Levels with a Differential

Controlling the water level on a boiler or deaerator is critical to boiler room operation. Without proper water level control, vessels will run out of water and/or have constant issues related to too much or too little water. If a deaerator runs out of water, the pumps will shut off and eventually the boiler will also shut down due to low water.
