Input/Loss Method - Benchmark Testing




As part of Exergetic Systems' benchmark testing program, 1200 ultimate coal analyses involving 12 Ranks and speciality coals from over 400 mines, were processed through Input/Loss. This work demonstrated standard deviations in LFuel can be <0.10% for certain Ranks (for example, LFuel for Low Volatile Bituminous coal is 792.82 lbmDry-Effluent/million-BtuFuel ±0.049%). Even for some of the poorest lignites, standard deviations in LFuel have been found at ±0.275%. 

Using these 1200 chemistries with Input/Loss Methods - with imposed errors on effluent concentrations - resulted in proof-of-process comparisons. This plot does not demonstrate Input/Loss accuracy per se, but only the validity of generic Input/Loss Methods. For a studied fuel, reasonably behaved, errors in heating value are typically ± 0.50%.
