The first water-tube boiler having fire tubes within water tubes was built in 1830, by Summers & Ogle. Horizontal connections at the top and bottom were connected by a series of vertical water tubes, through which were fire tubes extending through the horizontal connections, the fire tubes being held in place by nuts, which also served to make
In the boiler shown above, the furnace is fully water-cooled and of monowall construction, it is produced from finned tubes welded together to form a gastight casing. With monowall construction no refractory material is necessary in the furnace. The furnace side, floor and roof tubes are welded into the steam and water drums.
The Gresley W1 4-6-4 "Hush-Hush" Locomotive. The experimental Gresley W1 No. 10000 "Hush-Hush" was the only 4-6-4 tender locomotive to run in Britain. It included a number of experimental features including a marine type water-tube boiler working at 450psi.
NOTE: Triad highly recommends that boiler feed water be treated before it enters the boiler. The water in the boiler should have a pH level of between 7.5 and 8.5, and in no case above 9.5. If feed water temperature is below 140°F it also requires an oxygen scavenger. See WATER in Section III of this boiler manual.
