Steam Heating Systems Part 3: Application and Benefits of Small Self-Contained Steam Pressure Regulators
/
In our last blog article, we discussed the advantages of distributing steam at pressures that are likely higher than the ideal pressure for condensing steam in a heating system. This necessitates the use of pressure reducing valves to reduce the steam pressure to….

/
Last week, we reviewed different types of steam humidifier distribution methods, which are inexpensive but have longer absorption distances. Many HVAC installations require very short or non-wetting absorption distances. Humidifier distribution panels provide solutions to this requirement. This week we'll review the options for...
What is Superheated Steam?
/By Mike Sneary
Superheated steam occurs when heat energy is added to saturated steam that is not in contact with liquid. When the heat energy is added, the steam temperature is increased above the saturation temperature. Superheated steam is referred to as ‘dry’ steam meaning it contains no water droplets. This effect can also occur when the pressure of saturated steam is reduced through a pressure control valve.
