   en.wikipedia.org/wiki/Chicago_and_North_Western...

   The locomotives has boiler pressed to 170 pounds per square inch (1.2 MPa) feeding steam to two cylinders that had a 25-inch (640 mm) bore and a 32-inch (810 mm) stroke. These were connected to 61-inch (1,500 mm) driving wheels buy Walschaerts valve gear, although the last 47 were built with Baker valve gear. They had 14-inch (360 mm) piston ...

   The "standard" variety of large-boiler C1 was represented by nos. 251, 272–291, 293–301, 1400–20 and 1422–51 built at Doncaster between 1902 and 1908. These had boilers producing saturated steam at a pressure of 175 lbf/in 2 (1,210 kPa) and two outside cylinders, having a diameter of in (480 mm) and a stroke of 24 in (610 mm) using ...

4. NER Class Y - Wikipedia

   en.wikipedia.org/wiki/NER_Class_Y

   The Class Y locomotives were intended for hauling coal trains and were developed from the NER Class X (LNER Class T1) 4-8-0T heavy shunters. However, they had larger boilers and smaller cylinders for higher working speeds. Twenty were built in one batch and numbered between 1113 and 1195. Originally built with saturated boilers pressed to 175 ...

5. Vertical fire-tube boiler - Wikipedia

   en.wikipedia.org/wiki/Vertical_fire-tube_boiler

   The Stanley boiler is constructed of a seamless copper tube shell, 13 + 1 ⁄ 2 inches (340 mm) in diameter and 1 ⁄ 16 inch (1.6 mm) thick. The numerous 1 ⁄ 2 inch (13 mm) tubes are densely packed, leaving a very small water volume between them and a high ratio of heating surface to volume, for rapid steam raising. Construction of the ...

6. Hydronics - Wikipedia

   en.wikipedia.org/wiki/Hydronics

   Hydronics (from Ancient Greek hydro- 'water') is the use of liquid water or gaseous water ( steam) or a water solution (usually glycol with water) as a heat-transfer medium in heating and cooling systems. [ 1][ 2] The name differentiates such systems from oil and refrigerant systems. Historically, in large-scale commercial buildings such as ...

7. Shell-and-tube heat exchanger - Wikipedia

   en.wikipedia.org/wiki/Shell-and-tube_heat_exchanger

   A shell-and-tube heat exchanger is a class of heat exchanger designs. [ 1][ 2] It is the most common type of heat exchanger in oil refineries and other large chemical processes, and is suited for higher-pressure applications. As its name implies, this type of heat exchanger consists of a shell (a large pressure vessel) with a bundle of tubes ...
