The DRG H 02 1001 was a high-pressure steam locomotive built by the engineering firm of Berliner Maschinenbau (formerly L. Schwarzkopff) to the design of Dr L. Löffler. [1] The aim was not only to improve fuel economy—the usual reason for adopting high steam pressures—but also to increase the amount of power that could be produced within ...
Boilers generally have 2 or 3 pressuretrols: a manual-reset pressuretrol, which functions as a safety by setting the upper limit of steam pressure, the operating pressuretrol, which controls when the boiler fires to maintain pressure, and for boilers equipped with a modulating burner, a modulating pressuretrol which controls the amount of fire.

Napier boiler: A high-domed low-pressure boiler used on early steamships. [41] Also known as the "haystack", although not the usual, and even earlier, haystack boiler. [41] Niclausse boiler: a field-tube boiler, with the field-tubes set at a shallow angle to horizontal. [6] [42] Normand boiler: an early three-drum boiler used mainly by the ...
A modern recovery boiler consists of heat transfer surfaces made of steel tube; furnace-1, superheaters-2, boiler generating bank-3 and economizers-4. The steam drum-5 design is of single-drum type. The air and black liquor are introduced through primary and secondary air ports-6, liquor guns-7 and tertiary air ports-8.
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 ]
At that time, about 5,000 locomotives with hot steam technology were operated in Germany and abroad. A high-pressure piston steam engine with four cylinders was invented. [4] [5] The Schmidt-Hartmann high-pressure boiler was introduced in 1925; it dominated the German boiler market for more than two decades.
In 1922, Mark Benson was granted a patent for a boiler designed to convert water into steam at high pressure. Safety was the main concern behind Benson's concept. Earlier steam generators were designed for relatively low pressures of up to about 100 bar (10 MPa ; 1,450 psi ), corresponding to the state of the art in steam turbine development at ...
