The purpose of the paper is to present a concept of energy efficiency and financial evaluation of counterflow dryer. Energy efficiency and many other efficiency indexes of the dryer and all additional devices like heater, heat exchangers, tubing and fans are calculated. Expert system provides also the financial evaluation of the investment. Many investments could be considered. The system provi...

This paper present the modeling, analysis of 8/6 SRM using Fuzzy logic with Hybrid observer algorithm. In this algorithm the estimation of rotor position speed and error of speed is measured respectively. This algorithm has been simulated with MATLAB / Simulink for non-linear model of 8/6 SRM and has been designed with Hybrid observer using Current Sliding Mode Observer and Flux Linkage Mode Ob...

The thin layer drying of pine forest residues consisting of bark, needles, leaves, and chips was experimentally conducted at air temperatures of 40, 50, 60, 70, and 80C. Physical and chemical properties of fractionated forest residues were determined to evaluate its fuel properties. The experimental data obtained from thin layer drying study were fitted with Lewis, Page, and Henderson and Pabis...
