The complete Boilers & Steam System Management program consists of 8 modules (individual PowerPoint presentations). This document refers to the training module 2 only: Boiler Plant Efficiency.
Steam flow is the rate of steam leaving the boiler - the demand. Water flow is the rate of feedwater flow into the boiler - the supply. Drum level reflects the amount of water in the boiler - the inventory. With changes in boiler load (steam flow), steam and water flow become unbalanced and water level consequently deviates from the normal
