PROBLEMS 3.1 Assume that the fuel inputs in MBtu per hour for units 1 and 2, which are both on-line, are given by H, = 8P, +0.024P² +80 H, = 6P, +0.04P, +120 where H, = fuel input to unit n in MBtu per hour (millions of Btu per hour) = unit output in megawatts a. Plot the input-output characteristics for each unit expressing input in MBtu per hour and output in megawatts. Assume that the minimum loading of each unit is 20 MW and that the maximum loading is 100 MW. b. Calculate the net heat rate in Btu per kilowatt-hour, and plot against output in megawatts. c. Assume that the cost of fuel is 1.5 $/MBtu. Calculate the incremental pro- duction cost in $/MWh of each unit, and plot against output in megawatts.
