Fry's Equation: E b = k 1 – k 2 x M/G, where: Eb = Boiler Efficiency. M = Firing Rate. G = Grate Area. k1 = predicted boiler efficiency at zero firing rate. k2 = the slope of the graph relating boiler efficiency to firing rate. Boiler efficiency may also be defined as the amount of energy released from the boiler in the form of steam Learn More
