Input / loss technology is a unique technology that provides the basis for a full understanding of thermal processes in power plants through the analysis of fuel and its seepage flow, fuel chemistry, fuel heat value, and thermal efficiency. Low net (net) heat and high (total) heat and thermal efficiency can be determined, but direct fuel or discharge flow measurements are not given. Given its intention to be used in coal-fired power plants, input / loss techniques determine the flow and heat of coal through iterative techniques and divergence measurements based on the turbine cycle energy flows and boiler operating characteristics. Divergence measurements are based on multidimensional minimization techniques. The multidimensional minimization technique can correct the fuel for a given coal species within a standard error of less than ± 2% and the corrected results can prove to be substantially stable. Typical calorific values can be predicted at 0.5% accuracy. It is designed for online monitors. This method has been extensively validated by 1220 elemental analyzes and 10 years of pilot testing.
