From the boiler manufacturer's standpoint, the only way of establishing an efficiency that has any value when guarantees are to be met, is to require the grate or stoker manufacturer to make certain guarantees as to minimum CO 2, maximum CO, and that the amount of combustible in the ash and blown away with the flue gases does not exceed a certain percentage.

A simple mathematical proof that, based on Fry's equation, boiler efficiency at the grate limit is exactly half the maximum efficiency, is as follows: Fry's Equation: E b = k 1 – k 2 x M/G, where: E b = Boiler Efficiency; M = Firing Rate; G = Grate Area; k 1 = predicted boiler efficiency at zero firing rate

The efficiency so determined is used in comparing the relative performance of boilers, irrespective of the type of grates used under them. If the loss of fuel through the grates could be entirely overcome, the efficiencies obtained by and would obviously be the same.Hence, in the case of liquid and gaseous fuels, where there is practically no waste, these efficiencies are almost identical.
