Планування виробничих експериментів для багатофакторного дослідження технології сушіння торфу в парових трубчатих сушарках

Abstract

The paper highlights the necessity for planning the experiment in steam pipe dryers of peat for multivariate investigation of the drying process and for further searching power saving regimes of drying. Analysis of plans of experiments allowed to identify the main criteria for the construction plan of the experiment in steam pipe dryer. The basis for the planning of the experiment should take regime maps of tube steam dryers, which provide required quality of a dried peat and changing of control actions carry out in the range of operating conditions. In order to decrease the number of experiments, and also not to rid planning matrix its best features is necessary to develop fractional factorial experiment (FFE) and to identify fractional replica. The optimal experiment’s plan for creating a mathematical model of the drying process is FFE 25-1 with shoulder g=1 and experiments in the center of the plan.
