“…The used water, its pureness, temperature and pressure, constitute an important elements, to guarantee the efficient operation and the thermo-exergetic efficiency analysis of this facilities [4]. Also, come to be relevant the vapor and his quality, fuel and their properties, the air excess, The volumetric flows of air and combustion gases, this last element generate fouling and corrosion on the heat transfer surface, reducing their efficiency [5].…”

In this work, was made a thermo-exergy evaluation of four steam boilers that are used in the thermoelectric power plant belong to a Cuban productive company, which, have not been sufficiently studied from the energy point of view. The methodology for the estimation of the thermal and exergy efficiency values of these facilities is established and systematized in an algorithm. For this purpose, in this paper the GOST method is used in the assess evaluation of the steam boilers (direct and indirect method). The final results show a high correspondence between the gross thermal efficiency values obtained by the direct and indirect methods, their difference does not exceed 2.7% in the 87.5% of each variant calculated and the average value was 1.89%. The use of the thermal energy and the exergy in the boilers compute values near of 90.14 and 46.42% respectively. The application of proposal procedure shows a favorable behavior of the facilities object of study in this paper.
