27) By comparison, today's water-tube boilers safely operate at 5,000 psi and can deliver superheated steam at over 500 degrees Centigrade.
63) The water-tube boiler, invented by the Americans George Babcock and Stephen Wilcox in 1867, was itself not technologically feasible until the advent of twentieth-century metallurgy and electric welding techniques.
Newer ships had Yarrows water-tube boilers
that were much more efficient and somewhat cleaner, but a beast to work in.
Production of personal computers, boiler components and water-tube boilers

Commercial sales of smaller low-pressure steel-firetube, copper-fin and water-tube boilers
for heating applications are at record levels.
The Power Plant's water-tube boilers
were coal fired, and the transit company soon found it was cheaper to buy hydroelectric power generated elsewhere.
