A steam boiler is needed as part of the design of a new plant. The boiler can be fired by natural gas, fuel, or coal. A decision must be made on which fuel to use. An analysis of costs shows that the installed cost, with all controls, would be at least for natural gas at 30000, for fuel oil it would be 55000, and for coal it would be 180000.
