  • Steam boiler pressure and brew temperature for HX espresso

    Apr 14, 2015 · Steam boiler pressure and brew temperature for HX espresso machine. For example, if the boiler pressure is set at 1.4 bar the temperature of the water inside the boiler is too hot to brew (230F as per your chart) so we do a cooling flush to lower the temperature. We then need to pull the shot before it gets back to 230F.Learn More

  • Steam explosion - Wikipedia

    A common operating temperature and pressure for a marine boiler is around 950 psi (6,600 kPa) and 850 °F (454 °C) at the outlet of the superheater. A steam boiler has an interface of steam and water in the steam drum, which is where the water is finally evaporating due to the heat input, usually oil-fired burners.Learn More
