For example, a two-pass boiler provides two opportunities for hot gases to transfer heat to the boiler water. Hot combustion gases enter the tubes in a turbulent flow regime, but within a few feet, laminar flow begins and a boundary layer of cooler gas forms along the tube walls. This layer serves as a barrier, retarding heat transfer.

Reasons why the water is bouncing in the gauge glass, and

Jun 25, 2014· When the steam bubbles condense, the water in the boiler falls to a point lower than the water in the gauge glass. The water in the gauge glass offsets this by falling into the boiler. This usually turns on the low-water cutoff or the automatic water feeder. You wind up with nagging water level problems in the boiler.

Boiler Efficiency and Steam Quality: The Challenge of

Since steam is produced by the rapid boiling of water in high-heat flux boilers, it can entrain (or draw in and transport) water as it escapes from the water surface. This entrainment, while damaging to the steam system, is independent of boiler efficiency.
