  • Engineering Timelines - Richard Trevithick - High pressure steam

    The first of Trevithick's high pressure engines, a steam whim working expansively at 172kN per sq m (25psi), was begun at Cook's Kitchen mine in 1800. It had a 480mm diameter cylinder with a 1.52m stroke and was still working in 1870. To cope with the higher pressure, he designed a wrought iron cylindrical boiler with internal "tube and fireplace".

  • Introduction to Steam Distribution | Spirax Sarco

    A kilogram of steam at a higher pressure occupies less volume than at a lower pressure. It follows that, if steam is generated in the boiler at a high pressure and also distributed at a high pressure, the size of the distribution mains will be smaller than that for a low-pressure system for the same heat load.
