Model H.E. Steam Boilers - lattnerboiler.com
2014-4-10 · A bad check valve will allow hot water from the boiler to back-feed to the pump. When the pump starts, this water flashes to steam. This condition, known as cavitation, causes the pump to sound like there are ball bearings in the water and prevents the pump from working properly, especially when the boiler pressure rises.

The Importance of Expansion and Drain Structure in
The provisions made for thermal expansion and draining of the thermal oil are key factors to consider for the successful installation of any thermal oil heating system. Important system design principles like this often are overlooked; instead, the focus is placed on specific components like pumps, valves or the heater itself. Because most thermal fluid heating systems are closed-loop systems

What is a Boiler Deaerator and How Does It Operate?
2020-6-7 · Boiler deaerators commonly are used to remove oxygen and other gases from the water that feeds into boilers that generate steam. Deaerators are useful because they remove the gases that attach to the metallic components of the steam system and cause corrosion by forming oxides, or rust.
