The model E had been developed by 1922; this could be said to be the "classic" Doble, of which the most examples have survived. The initial monotube boiler design was perfected into the "American" type. This produced steam at a pressure of 750 psi (52 bar) and a temperature of 750 °F (400 °C). The tubing was formed from seamless cold-drawn ...
A steam generator is a type of boiler used to produce steam for climate control and potable water heating in railroad passenger cars. The output of a railroad steam generator is low-pressure, saturated steam that is passed through a system of pipes and conduits throughout the length of the train. Steam generators were developed when diesel ...
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).
Steam can be drawn off as required, either for driving a steam turbine or for process purposes (e.g. in chemical engineering), by opening a steam valve on top of the drum. . The pressure in the drum will fall but the reduced pressure causes more water to boil and the accumulator can go on supplying steam (while gradually reducing pressure and temperature) for some time before it has to be re-char
The first experimental steam-powered cars were built in the 18th and 19th centuries, but it was not until after Richard Trevithick had developed the use of high-pressure steam around 1800 that mobile steam engines became a practical proposition. By the 1850s there was a flurry of new steam car manufacturers.
The ASME Boiler & Pressure Vessel Code (BPVC) is an American Society of Mechanical Engineers (ASME) standard that regulates the design and construction of boilers and pressure vessels. [1] The document is written and maintained by volunteers chosen for their technical expertise . [ 2 ]

The compact engine ran at considerable steam pressure, with the 10-horsepower (7.5 kW) boiler described in 1912 [6] as having the safety valve set at 650 pounds per square inch (4.5 MPa), with the burner set to automatically cut back when pressure reached 500 pounds per square inch (3.4 MPa).
