| Abstract: | Results of investigations of the physico-mechanical and aerodynamic characteristics of granular materials used as channel
fillers in the temperature compensators of convective shafts of boiler units are presented. Possible causes of influxes of
air into gas conduits of the boiler through a sand compensator are analyzed. A multilayer procedure is proposed for filling
of the bulk compensator, and computational relationships are presented for determination of the height of each layer and its
aerodynamic resistance. Results of the investigations were implemented at the Krasnoyarsk TéTs-2 thermoelectric power station
(TEPS) during assembly of the No. 6 BKZ-500-140 boiler.
