All pipeshave been provided with the loose-type flange, known as theVan Stone flange. From the header the branches lead to theturbines, the sizes of which are as follows: lo-in. pipe to the 2000-kw turbines and a 12-in. pipe to the 5000-kw 12-in. pipes were chosen because of the use of super-heated steam, which enables a greater velocity than saturatedsteam. As the turbines operate with 17 lbs. steam per kilo-watt, and the volume of superheated steam, at 150 degs., ispractically 30 per cent greater than that of saturated steam. PLAN OF POWER STATION
