ECONOMIZADOR A BASE DE ENERGIA SOLAR PARA OTIMIZAR A EFICIÊNCIA EM CALDEIRAS

Abstract

This paper discusses a study on solar collectors for a preheating of the water in a boiler. Solar collectors ensure that the boiler receives the preheated water, thus generating fuel savings and increasing boiler efficiency. Such an approach is necessary to optimize the use of boilers in the renewable energy industries and generating cost reduction. The objective of this study is to perform a comparative in boilers with and without the use of solar collectors and to evaluate their expenditures and energy efficiency. This task will be obtained through bibliographic review and case study. Solar collector efficiency data will be collected. After this data collection will be made calculations of energy expenditure, efficiency and fuel costs of the boiler without the use of solar collectors and later with the use of solar collectors. The calculations show that the use of the economizers increase the efficiency of boilers by 5.43% and a fuel saving of 37.23 m³ of natural gas per hour for the generation of steam.
