Vessels typically contained several engines for different purposes. Main, or propulsion engines are used to turn the ship's propeller and move the ship through the water. . The fire room got its name from the days when ships burned coal to heat steam to drive the steam engines or turbines; the room was where the stokers spent their days shoveling coal continuously onto the grates under the ...
Two designs were offered to the Admiralty, who required prototypes for subsequent destroyer construction. Thornycroft's "A" design used the maximum length allowed (310 ft between perpendiculars). The "B" design—which was adopted—reduced the length by 5 ft (1.5 m), using only one boiler room forward (as in their wartime Wishart).
Daring was on the end of the line with HMS Diana on her starboard side. When the 'Execute' order was received, Diana failed to respond and Daring turned directly at her. The first lieutenant was on the bridge with the Capt. in the radar plot room. I was i/c 'B' boiler room and saw the repeater telegraph move to "Full Astern".
The design was intended as a smaller follow-on from the preceding Tribal class. In a departure from all previous Royal Navy destroyers, the design used a two boiler room layout. This reduced hull length and allowed for a single funnel, both reducing the profile and increasing the arcs of fire of the light anti-aircraft (AA) weapons. It also ...
The uptakes of the two forward boiler rooms were trunked together aft of the break in the forecastle into the fore funnel while the rear boiler room exhausted into the smaller rear funnel. Both funnels were inclined to the rear to reduce the amount of smoke that might reach the bridge. A tripod mast was fitted between the bridge and the fore ...
The ship was targeted by more Stukas diving from each side, making evasive manoeuvres ineffectual. She was hit by two bombs, one passing through the wireless telegraphy office and exploding beside the forward boiler room, the second hitting just forward of the bridge and starting a severe fire at the after end of the mess decks.
In these two ships, the position of the boiler rooms was reversed, with the two-boiler room forward and the single unit aft. As a result, the funnel arrangements were transposed, with the thick funnel forwards and the narrow funnel aft. In common with other Thornycroft designs, they had characteristic broad, flat-sided funnels.
The turbines, each in their own engine room aft of the boiler room, were designed to produce a total of 60,000 shaft horsepower (45,000 kW) and a speed of 35 knots (65 km/h; 40 mph) in service. [4] The ships carried a maximum of 740 metric tons (730 long tons) of fuel oil to give them an estimated range of 3,300 nautical miles (6,100 km; 3,800 ...
