Water Handbook - Boiler System Failures | SUEZ

In some steam drum designs, water level is extremely critical because the baffling may isolate a generating section of the boiler when the steam drum water level falls below a certain point. Thin-lipped bursts also occur in superheater tubes when steam flow is insufficient, when deposits restrict flow, or when tubes are blocked by water due to a rapid firing rate during boiler start-up.

Steam is generated in the boiler of a cogeneration plant at $10 mat{MPa}$ and $450^{circ} mat{C}$ at a steady rate of $5 mat{kg} / mat{s}$. In normal operation, steam expands in a turbine to a pressure of $0.5 mat{MPa}$ and is then routed to the process heater, where it supplies the process heat.
