THE USE OF THERMAL METHODS TO PROTECT THE EXHAUST-CHANNELS OF BOILERS EQUIPPED WITH HEAT-RECOVERY UNITS

Thermal methods for protecting the exhaust-ducts of boiler plants from corrosion damage due to the formation of condensate on their inner surface are considered. Methods such as are proposed and investigated: bypassing exhaust-gases, mixing with dry heated air, heating in a surface heat-exchanger - gas heater. The use of these methods will significantly improve the thermal and humidity condition of chimneys and increase their service life.
