EXPERIMENTAL STUDY OF AERO- AND HYDRAULIC SYSTEMS IN A DIRECT-FLOW BOILER ON A LABORATORY STAND WITH THE INTRODUCTION OF AUTOMATIC CONTROL OF DEVICES AND DATA COLLECTION

Abstract

Few laboratory stands can simulate the operation of direct-flow boilers. The processes occurring therein are complex both hydraulically and thermophysically. A study of the fluid dynamics of the coolant in a cylindrical compo-site coil shows that it is possible to influence boiler performance. The movement of air through coils is also of interest for the intensification of the heat exchange process in direct-flow steam boilers. Modern automation devices can make allow for readings to be taken of the coolant and air with high accuracy. They cal also transfer experimental values to a personal computer for data storage and subsequent analysis. The article presents the results of the design and assembly of a laboratory stand, designed for experimental research of aero- and hydraulic systems of a direct-flow boiler using automatic device control and data collection. The results of modeling and experimental data are presented herein.
