Carbon Monoxide's Impact on Indoor Air Quality | US EPA

Oct 22, 2020 · It is most important to be sure combustion equipment is maintained and properly adjusted. Vehicular use should be carefully managed adjacent to buildings and in vocational programs. Additional ventilation can be used as a temporary measure when high levels of CO are expected for short periods of time. Keep gas appliances properly adjusted.

Superheated Steam - an overview | ScienceDirect Topics

Aug 02, 1970 · Superheated steam is steam heated to a temperature higher than its boiling point corresponding to the operating pressure. Figure 3 shows the schematic diagram of basic principle of a closed system superheated drying system. Saturated steam (100 °C, 1 bar) after heated to a superheated state at 110 °C, gaining 30 kJ kg −1 of energy, if it is used as a drying medium, absorbs moisture from

Boiler Pressure Too High, Low, Keeps Rising, Dropping

What should your pressure be? The ideal boiler pressure should be between 1 to 1.5 bars on your pressure gauge when your heating is switched off. Around 2 bars is a normal pressure level when your boiler is active/heating up. Anything below 0.5 is too low and must be replaced. Is Your Boiler Pressure Too High Or Low?

Water Handbook - Preboiler & Industrial Boiler Corrosion

Steam blanketing is a condition that occurs when a steam layer forms between the boiler water and the tube wall. Under this condition, insufficient water reaches the tube surface for efficient heat transfer. The water that does reach the overheated boiler wall is rapidly vaporized, leaving behind a concentrated caustic solution, which is corrosive.
