EFFECT OF TEMPERATURE MODE FERMENTATION AND SEDIMENTATION PARAMETERS OF THE SUBSTRATE ON THE PERFORMANCE OF BIOGAS INSTALLATION

Abstract

The influence of fermentation temperatures and sedimentation settings substrate for biogas production.Considered the three stage anaerobic process, namely kriofile, mesophile and thermophile. In polydisperse sedimentation characteristics of the substrate environment affect its density and size of particulate matter, as well as speed mixing device to install. A mathematical model of biogas with regard to speed, factors that affect the performance of the installation. The results of numerical simulations obtained regression equation describing the relationship between performance and biogas temperature and sedimentary organic substrate parameters. Constructed images of surfaces guest depicting the relationship between the objective function, optimization criterion and independent variables are presented anaerobic fermentation temperature, stirring speed and humidity of the substrate.
