Methodology of the fuels certification by consideration the last as the commodity products has been composed basing on option of the main power characteristics and on statement of their compliance with the values regulated by the standards. The most significant fuel parameters that evaluate the fuel’s suitability for use in specific combustion plants were selected. High and low combustion heat values, along with the theoretical combustion temperature have been proposed as the main heat engineering parameters for the fuels evaluation. The Wobbe indices, high and low, are considered as well among the fuel characteristics to be estimated. Calculations of the calorific values by the original author’s techniques for a range of fuels, including alternative fuel gases and the gas mixtures — analogs of the natural gases produced from different gas fields, were performed. The author’s calculated results of main heat engineering parameters of fuels were compared with the data obtained by measurements and calculations, tabulated in reference books of foreign sources. It has been established that the relative divergences for mentioned values have a minimum difference (less than 1 %). The calculated dependencies for definition the flow rates of the low and high calorific fuels based on accounting the differences between the total enthalpies of the air-fuel mixture and combustion products of appropriate fuels are presented. A method of forming the price on consumable fuel has been proposed taking into account the different cost of 1 MJ of the energy for various fuels under consideration.
