The EMPRESS OF ASIA was steam powered.\u00a0\u00a0The steam was produced in 10 cylindrical Scotch boilers.\u00a0\u00a0Each boiler was filled with water that was heated by furnaces that passed fire through tubes that ran through the boiler.\u00a0\u00a0When the hot gases had been expended the exhaust was vented through the ship’s three stacks.<\/p>\n\n\n\n
Six of the boilers were double ended and four were single ended. Each end contained three furnaces, giving the ship a total of sixty-four furnaces.<\/p>\n\n\n\n
The EMPRESS OF ASIA was coal fired.\u00a0\u00a0Trimmers delivered coal through chutes and wheelbarrows to firemen who cared for the furnaces.\u00a0\u00a0It was the firemen’s responsibility to maintain the fires in the furnaces.\u00a0\u00a0A slice bar was used to turn the coal to ensure a thorough burn.\u00a0\u00a0Ash needed to be removed from the fires regularly. The boilers produced a pressure of 190 psi.<\/p>\n\n\n\n
The boilers were capable of consuming 300 tons of coal a day. A typical round trip to the Orient would take approximately 6 weeks and would consume over 10,000 tons of coal.<\/p>\n\n\n\n
The engines consisted of four Parsons turbines; a type designed by the British engineer Charles Parsons. The turbines were connected to the boilers and the steam passed first through the high-pressure turbine, then the intermediate pressure turbine and finally into the two low pressure turbines. Each turbine was directly coupled to a 9-foot propeller that turned at the same speed as the turbine. The EMPRESS OF ASIA engines were rated at 18,500 horsepower.<\/p>\n\n\n\n
Additional turbines were fitted to the low-pressure shafts to provide astern propulsion.<\/p>\n\n\n\n
\u00a0When the used steam exited the last turbines it passed into the condenser where it was returned to water by contacting cooling pipes circulating cold seawater.\u00a0\u00a0The newly formed water from the condenser was returned to the boiler and the warmed seawater was discharged over the ship’s side.\u00a0\u00a0This discharge is often visible on photographs of the EMPRESS OF ASIA when the ship is underway.<\/p>\n\n\n\n
The engine is maintained by a group of engineers and greasers who repaired and maintained the engines.<\/p>\n\n\n\n
The engine room was labour intensive and required a large crew.\u00a0\u00a0Typically the engine room would consist of over 150 men.\u00a0\u00a0When the EMPRESS OF ASIA sailed from Vancouver on\u00a0Feb 13, 1941\u00a0bound for Liverpool, the Engine Department totalled 152 individuals.<\/p>\n\n\n\n The EMPRESS OF ASIA was steam powered.\u00a0\u00a0The steam was produced in 10 cylindrical Scotch boilers.\u00a0\u00a0Each boiler was filled with water that was heated by furnaces that passed fire through tubes that ran through the boiler.\u00a0\u00a0When the hot gases had been expended the exhaust was vented through the ship’s three stacks.
