    2020-2-5 · The HP boiler worked at approx 850 psi (5.86 MPa), and the low-pressure boiler at 200 to 250 psi (1.38 to 1.72 MPa). The UHP and HP boilers were of a water tube design, while the LP boiler was a fire tube boiler typical for steam locomotives. The LP cylinders were driven with a mixture of the HP cylinder exhaust and the LP boiler output.

    2019-12-4 · Steam is then pumped from the top of the boiler to wherever heating is needed. The boiler contains a safety valve that, when the pressure becomes too high due to blockage or overheating, releases the excess steam. Take a three­pass fire tube steam boiler with a capacity of 5000 kg of steam per hour and a operating pressure of 10 bar for example.

    The boiler is better able to respond to large loads as the ‘low fire’ position will ensure that there is more stored energy in the boiler. If the large load is applied when the burner is on ‘low fire’, it can immediately respond by increasing the firing rate to ‘high fire’, for example the purge cycle can be omitted.
