Automation of the burner of a pirotubular boiler to improve the efficiency in the generation of steam

<span>The purpose of this article is to describe the automation developed by means a programmable logic controller for burner fire tube boiler, in order improve efficiency process generating steam quantified through percentage oxygen generated. The implementation was under control strategy based on use servomotors that allow gradually open or close solenoid valves dose amount air and fuel; Considering there are multiple elements, I limited analysis one its main components, called burner. After developing automation, it possible demonstrate decrease variability relation optimal desired value boiler. experimentally obtained data percentage, were subjected statistical dispersion, which Pearson's correlation coefficient determined, whose equal 0.298; This result allowed conclude degree indicator with respect time very low, variable maintains constant value, after automating boiler</span><span lang="IN">.</span>
