30/8/2019 · In Fire Tube Boilers, hot flue gases will be flown inside the tube and these tubes are surrounded by water. These are the low-pressure boiler which cannot generate much heat compared to water tube boilers. As the production of heat is less the overall efficiency of this boiler is also low.

Thermodynamic Design of a Fire­Tube Steam Boiler

Violent bursts of the thin-lipped variety occur when water circulation in the tube is interrupted by blockage or by circulation failure caused by low water levels. 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.
