  2. Steam - Wikipedia

    en.wikipedia.org/wiki/Steam

    An autoclave, which uses steam under pressure, is used in microbiology laboratories and similar environments for sterilization. Steam, especially dry (highly superheated) steam, may be used for antimicrobial cleaning even to the levels of sterilization. Steam is a non-toxic antimicrobial agent. [11] [12]

  3. Superheated steam - Wikipedia

    en.wikipedia.org/wiki/Superheated_steam

    Superheated steam was widely used in main line steam locomotives. Saturated steam has three main disadvantages in a steam engine: it contains small droplets of water which have to be periodically drained from the cylinders; being precisely at the boiling point of water for the boiler pressure in use, it inevitably condenses to some extent in the steam pipes and cylinders outside the boiler ...

  4. Steam engine - Wikipedia

    en.wikipedia.org/wiki/Steam_engine

    High-pressure steam (red) enters from the boiler and passes through the engine, exhausting as low-pressure steam (blue), usually to a condenser. It is a logical extension of the compound engine (described above) to split the expansion into yet more stages to increase efficiency.

  5. High-pressure steam locomotive - Wikipedia

    en.wikipedia.org/wiki/High-pressure_steam_locomotive

    A high-pressure steam locomotive is a steam locomotive with a boiler that operates at pressures well above what would be considered normal for other locomotives. Most locomotives operate with a steam pressure of 200 to 300 psi (1.38 to 2.07 MPa). [1] In the later years of steam, boiler pressures were typically 200 to 250 psi (1.38 to 1.72 MPa).

  7. Compound steam engine - Wikipedia

    en.wikipedia.org/wiki/Compound_steam_engine

    In a single-expansion (or 'simple') steam engine, the high-pressure steam enters the cylinder at boiler pressure through an inlet valve. The steam pressure forces the piston down the cylinder, until the valve shuts (e.g. after 25% of the piston's stroke). After the steam supply is cut off the trapped steam continues to expand, pushing the ...

  8. Boiler (power generation) - Wikipedia

    en.wikipedia.org/wiki/Boiler_(power_generation)

    The steam produced has lower density than the water and therefore will accumulate at the highest level in the vessel; its temperature will remain at boiling point and will only increase as pressure increases. Steam in this state (in equilibrium with the liquid water which is being evaporated within the boiler) is named "saturated steam". For ...

  9. Compounding of steam turbines - Wikipedia

    en.wikipedia.org/wiki/Compounding_of_steam_turbines

    The steam coming from the boiler is fed to the first set of fixed blades i.e. the nozzle ring. The steam is partially expanded in the nozzle ring. Hence, there is a partial decrease in pressure of the incoming steam. This leads to an increase in the velocity of the steam. Therefore, the pressure decreases and velocity increases partially in the ...
