46 can be used directly for determiningthe cost of fuel. For example: The boilers are guaranteed toevaporate, with a given coal containing 14,400 B.t.u. and costing$4.60 per ton, 10 lbs. of water per lb. of fuel. The boiler efficiency-can be obtained from Fig. 45 by reading the nearest diagonal to… … 0 1 2 3 4 5 6 7, Lbs fuel Per HP HourFig. 46. Steam power — cost of fuel per horsepower hour. alone will require 16 lbs. of steam per i.h.p.-hr., that the engine willhave a mechanical efficiency of 95%, or that the steam per b.h.p.-hr. will be 16.84 lbs., and with a generator of 95% efficiency…
