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

Boiler losing pressure? Causes of low boiler pressure

Apr 26, 2021 · What the hell is boiler pressure and why do you need boiler pressure? Boiler pressure is simply the balance of water and air within your boilers sealed system.. In order to function correctly, your boiler needs a particular balance of water and air to ensure the pressure in the system is adequate for when water is demanded from the boiler – essentially when you switch on your heating or hot

How Fossil Fuels are Used to Generate Electricity

Jan 06, 2020 · Alternatively, electricity from natural gas may be derived by piping natural gas underground to power plants. Similar to the process with coal, the power plants burn natural gas to boil water to produce steam. The steam spins the blades of a turbine that are connected to a generator. The generator then spins magnets to generate electricity.

An Introduction to CO2 Separation and Capture Technologies

A similar process is available for natural gas, where the syngas is formed by steam reforming of methane. The hydrogen route opens up opportunities for " polygeneration", where besides electricity and CO 2, additional products are produced. For example, instead of sending hydrogen to a turbine, it can be used to fuel a "hydrogen economy".
