The " Royal Sovereign "-class knots at 9, 000 indicated horsepower; 16.5 knots at 11, 000 indicated horsepower could be obtained with forced draught.
22.
The forced draught pressure in the boiler room would have supplied air through the rivet holes which would have caused the cork to give off flammable gases and eventually ignite the cordite charges.
23.
The engines were rated at, using forced draught, and designed to reach a top speed of although " Mikasa " proved to be faster during her sea trials in December 1901.
24.
The engines were rated at, using forced draught, and designed to reach a top speed of She carried a maximum of of coal which allowed her to steam for at a speed of.
25.
Many ships also used a forced draught to get additional power from their engines, and this system was widely used until the introduction of the steam turbine in the mid-1900s ( decade ).
26.
An extra knot or two of speed could be gained by applying a'forced draught'to the furnaces, where air was pumped into the furnaces, but this risked damage to the boilers.
27.
The " Royal Sovereign " s were powered by a pair of three-cylinder, vertical triple-expansion steam engines, each driving one shaft . Their cylindrical boilers with forced draught.
28.
Combustion air was delivered by two forced draught fans located above the coal bunkers, taking warm air from above the boiler roof casing and discharging it though rotating heat exchangers to the furnace wind boxes.
29.
The engines were rated at, using forced draught, and designed to reach a top speed of . " Yashima ", however, reached a top speed of from on her sea trials.
30.
"Clan Forbes " had 20 corrugated furnaces with a combined grate area of heating five single-ended forced draught boilers with a combined heating surface of that supplied superheated steam at 220 NHP.
