For coal of 13,500 70 per cent combined efficiency of grate, boiler andeconomizer, the rate of combustion is 17 lb. per squarefoot of grate surface at the rating of the unit. Both Motors and Turbines Are Used forAuxiliary Drive To make good use of the economizers forming a partof the boiler units in supplying the first turbo-genera-tor, it was important to restrict the amount of auxiliarysteam. On the other hand it was desired to provideenough steam even in winter to maintain a feed tem-.
