CALCULATION OF TEMPERATURE-HUMIDITY MODE OF BRICK AND REINFORCED CONCRETE CHIMNEYS WALLS

Abstract

The method for calculating the temperature-humidity mode of brick and reinforced concrete chimneys is presented. The processes of heat exchange of combustion products in the gas volume of the chimneys and heat and mass transfer in it’s walls also, are modeled. The parameters of vapour transfer in the walls of reinforced concrete chimneys in various operating modes of the boiler plant are calculated. The range of flue gases parameters at which the "dry" operating mode of a reinforced concrete chimneys is realized is determined.
