Engine Room
With 13 separate steam engines in one room, the Daldy’s engine room can get to be quite a busy place. My personal favourite is the main port engine. It always seemed to respond better than the starboard one!
The cylinder diameters are 15, 25 and 40in., the stroke being 30in. The high-pressure cylinder is fitted with a piston valve having Moss Philip rings, while the intermediate- pressure and low-pressure valves are of the Andrews and Cameron type. The piston rings are of the Lockwood and Carlisle type, and United States metallic packing is fitted to all the piston and valve rods. The exhaust from both engines is led to a common condenser, arranged athwartships at the after end of the engine-room. Two independent air pumps of the Weir design and a Drysdale centrifugal circulating pump are installed.
