摘要：

This study sought to analyze the viability of the use of solar energy, for the operation in boiler economizers, in the replacement of the thermal energy of the exhaust gases. The experiment was divided in two steps: analysis of the boiler yield with different feed water temperatures and addition of the solar field to the initial set. For the modeling of the economizer-boiler set, the software used was Engineering Equation Solver (Software F-Chart, Wisconsin, USA). The technology chosen for the second stage was the high-pressure vacuum solar collector, installed at the inlet of the feed water heater. The thermal power of 2014W (per plate) and the solar radiation peak of 1000W / m² were standardized, taking into account the calculations for a steady state system at noon. The variable was the number of solar panels to be used at the plant. After analyzing the data, it was verified that the efficiency varied by approximately 7.4%, when the feed water temperature was increased by 20 ° C, close to 48 ° C. In order for this variation to occur, it was necessary to use 50 plates. © 2021, European Association for the Development of Renewable Energy, Environment and Power Quality (EA4EPQ).
