ANÁLISIS ENERGÉTICO DE UN GENERADOR DE VAPOR DE 350 MW

Abstract

In this work has developed a methodology of energy analysis to determine the influence that environmental temperature has in the thermal efficiency of a steam generator of 350 MW that burns fuel oil to 100% charge and partial loads, which is installed in the Power plant of Villa de Reyes, San Luis Potosí. In order to carry out the work it was investigated environmental conditions of Villa de Reyes, extreme temperatures, average temperature along the year, on summer and in winter. The indirect method of thermal efficiency was applied, because this method takes into account the heat losses generated by the steam generator if environmental temperatures changed. The methodology consists of the calculation of heat losses that affect the performance of the steam generator. These losses of heat are the following: loss of heat with exhaust gases, loss of heat by chemical combustion incomplete, loss of heat by mechanical incomplete combustion and the loss of heat by convection and radiation. As a result it was obtained a variation of thermal efficiency at different environmental conditions, in this work when steam generator operates at extreme temperatures was found a maximum difference of thermal efficiency of 1.04 %.
