Boiler (power generation) - Wikipedia

A 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.

Compressor - Wikipedia

A compressor is a mechanical device that increases the pressure of a gas by reducing its volume.An air compressor is a specific type of gas compressor.. Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe.As gases are compressible, the compressor also reduces the volume of a gas. Liquids are relatively incompressible; while

How to Test a Furnace Pressure Switch - The Spruce

Dec 21, 2020 · If the furnace is operating correctly, the pressure switch senses the proper degree of negative pressure and remains open (off). But if the vent pipe gets blocked or if certain parts in the system fail, then the pressure switch recognizes that there is no longer the proper negative pressure, and it turns on (closes the circuit) to stop the operation of the furnace.
