(w) Low pressure boiler means a steam boiler on which the safety valves are set at pressures not exceeding 15 psi. (x) Maximum allowable working pressure means the maximum gage pressure permissible at the top of a completed vessel in its operating position for a designated temperature.
Read Morethe economizer, boiler steam generation tubes, super-heater tubes and air tubes. The specific gas temperatures in degrees centigrade for the following include: 150 – 370oC for the economizer, 1000 – 1650oC for the boiler steam generation tubes, 650 – 1000o– o
Read MoreSuperheated 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
