Stage 2. Analysis of the chimneys of industrial furnaces operating modes using a complex of methods and measures to increase their heat and environmental efficiency based on modeling external aerodynamics and heat transfer of pipes, taking into account the ground infrastructure of heat power plants and creating and testing a preproduction model of an information-measuring system for monitoring the concentration of pollutants. Development and implementation of recommendations based on research results popup.stage_title Head Prokopov Viktor Н., д.т.н.

It is shown that the local heat transfer differs from the average value along the tube height and is characterized by a periodic change in heat transfer due to the conical shape of the tube and the impact of the ground surface. A set of calculation and experimental studies of the analysis of operation modes of chimneys of regenerative type glass furnaces when using (and without them) technologies for recovery of waste heat of flue gases was performed. Recommendations on the use of methods to improve the operational reliability and environmental efficiency of industrial furnace chimneys with the introduction of heat recovery technologies, providing a 5-10% reduction in the use of fuel in the heat installations under consideration have been developed. A method for displaying in polar coordinates the results of measuring the characteristics of local fields of atmospheric air pollution, obtained during the movement of sensors in the vicinity of chimneys of heat-power installations, is proposed. A model for predicting the concentrations of air components based on the application of retrospective information and the discrete Fourier transform is proposed. The system of ambient air pollution monitoring of thermal power facilities based on distributed wireless sensor networks (Wi-Fi/mesh) was developed, it allows real-time monitoring of ambient air pollution state of a number of harmful substances, in particular PM1, PM2. PM10, CO2, CO, NOx, NH3, CH2O, etc. Product Description popup.authors Babak Vitalii P Bohachev Ihor V. Borisov Igor I. Gilchuk Andriy V. Glushak Oksana Yu Gnedash Georgii O Dekusha Oleg L.
