Predição do consumo de pellets no aquecimento de aviários de frango de corte

Abstract

Pinus pellets are an important product consumed worldwide and have been growing more and more over the years, as they are an option for generating heat with high efficiency and practicality. Furthermore, it is a form of clean and sustainable energy, very important for today, where the preservation of the environment is of paramount importance. This work aims to determine an equation to predict pellet consumption as a function of climatic variables. To do so, a database of a broiler producer integrated to a company in the sector was used. Data were collected from November 13, 2019 to February 21, 2021. The variables that make up the database are: consumption of electricity and pellets, ambient temperature (indoor and outdoor) and relative humidity (internal and external). To meet the objectives of this work, a correlation was made between the consumption of pellets and the other variables mentioned, using multiple linear regression analysis. The software used was Microsoft Excel. It was observed that the variables minimum internal temperature, maximum internal temperature and average external temperature had a significant effect, which were used in the equation, representing 58% of the variability of pellet consumption, with a variation of about 82.11 Kg day-1. Further studies are needed to reduce error and increase accuracy in predicting pellet consumption, taking into account other variables.
