What Is Steam Boiler?- Definition, Working, and Types - …

A steam boiler or steam generator is a device used to create steam by applying heat energy to water. Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

Water Handbook - Boiler System Failures | SUEZ

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.

Steam Boiler vs Hot Water Boiler - ATI of NY

2016/10/12 · Safety & Efficiency. In comparison to steam boilers, hot water boilers have been traditionally safer. At the same time, the efficiency of steam boilers has traditionally been less than that of hot waters. The reason for this difference is due to the fact steam boilers do not use motor pumps to enhance circulation.
