Prokopov, V.G. Navrodska, R.O. Shevchuk, S.I. Stepanova, A.I. The results of a complex of experimental studies of thermal and aerodynamic indicators of water-heating heat-recovery exchangers of dusty exhaust gases from glass-making furnaces are presented. The studies were carried out on an experimental installation located behind a glass-melting furnace, and in the process of start-up operations during the introduction into operation of modular-type water-heating heat exchangers (HWM) developed by IET NAS of Ukraine at various glass-producing enterprises. The studies were carried out using modern measuring equipment according to certified methods of the services of metrological adjustment of glass-making enterprises, with the participation of which the experiments were carried out. In the process of research, the heating capacity, average values of the heat transfer coefficients and aerodynamic resistance of heat exchange surfaces, which are assembled from of panel packages formed by pipes with membranes, under conditions of heat-recovery of dusty furnace gases, were determined. The dynamics of the formation of a layer of deposits of technological dust on the surface of the panels on the gas side and the contamination coefficient of surface were also subject to research. According to the data on the heat-recovery exchanger heating capacity, the rational period of its operation between cleaning the working surfaces was determined. The experimental parameters obtained were also compared with their calculated values, as well as with the data of other researchers. According to the results of the studies, it is shown that TVM heat exchangers when used in conditions of dusty furnace gases are characterized by high thermal efficiency due to the layout of the heat exchange surface from the packets of panels formed by pipes with membranes, and the possibility of cleaning these surfaces from deposits of technological dust with practical restoration of the initial indicators. Based on the data obtained, the duration of the cycles for cleaning membrane heating surfaces from dust deposits was determined: for furnaces for the production of glass packaging, this period was 10-14 days, and for furnaces for melting medical glass - 5-7 days.

The studies were carried out using modern measuring equipment according to certified methods of the services of metrological adjustment of glass-making enterprises, with the participation of which the experiments were carried out. In the process of research, the heating capacity, average values of the heat transfer coefficients and aerodynamic resistance of heat exchange surfaces, which are assembled from of panel packages formed by pipes with membranes, under conditions of heat-recovery of dusty furnace gases, were determined. The dynamics of the formation of a layer of deposits of technological dust on the surface of the panels on the gas side and the contamination coefficient of surface were also subject to research.
