Энергетические характеристики топлив и способы их определения

Abstract

Chemical energies and exergies reflect more correctly and completely the energy potentials of fuels than the calorimetric values that generally used in practical calculations. Using chemical energies and exergies for analysis of energy efficiencies in energetic and technological processes may greatly change the estimated levels of efficiencies for different technical systems. Available methods for estimating chemical energies and exergies are described and the results compared. One of the procedures is recommended for practical application in improved form. The results of calculations for coals of Eastern Siberia give as an example.
