This method must not be used on a boiler with a superheater or reheater or on a high-pressure, high-temperature water boiler.

     (b) By measuring the maximum amount of fuel that can be burned and computing the corresponding capacity for evaporation or generation of steam upon the basis of the heating value of this fuel. These computations must be made as set forth in the appendix of section I of the ASME Boiler and Pressure Vessel Code, as adopted by reference in NAC 455C.108.

     (c) By measuring the maximum amount of feed water that can be evaporated.
