CREATION AND EXPERIMENTAL TESTING UNIVERSAL SYSTEM OF ENVIRONMENTAL DIAGNOSTICS HEAT ENGINES AND BOILER INSTALLATIONS

Abstract

A description is given of an experimental sample of a universal system for the environmental diagnosis of heat engines and boiler installations, which was developed at the Department of Environmental Engineering of the O.M. Beketov National University of Urban Economy in Kharkiv. The properties of this system are: multi-functionality, compactness, mobility, ease of operation, a high degree of automation, informative results, ability to solve both research and training tasks. The structure, composition and functionality of the main modules of this system are considered: 1) measuring, which contains microtunnels МКТ-2, instruments and equipment for direct determination of indicators of chemical and physical pollution of the environment; 2) testing and demonstration, which consists of: installations for research of aerodynamic processes in exhaust systems of engines and boiler chimneys, laboratory transformer rack for mounting various test benches, a multimedia complex equipped with a tablet PC and an SMART information panel with a diameter of 43 " to demonstrate the operation of devices, equipment, programs, research results, etc.; 3) laboratory, which contains laboratory devices, equipment and consumables for the analysis of samples taken during environmental studies of natural objects. Normalized methods and techniques that allow to determine indicators characterizing chemical and physical pollution of the environment by heat engines and boiler installations are defined and systematized. Experimental testing of the created measuring system on full-scale objects: a gasoline engine of a passenger car - VAZ-21081 and automotive diesel engines - 4ЧН12 / 14, boilers with gas - DKVR-20/13 AOGV-100E and solid-fuel - КЧМ-2М-4 boilers. Tests confirmed the practical suitability of the measuring system.
