Abstract

PURPOSE: To keep heat transfer surface clean by providing spray pipes on the top of a secondary preheater.
CONSTITUTION: A secondary preheater 7 is provided in an air duct 13 at the underside of a rotary element 2. A plurality of spray pipes 8 are provided on the top of the secondary preheater 7. By this construction is opened a stop valve 9 of rinsing device for regenerated air preheater to spray warm water W from spray pipes 8 to the steam system air preheater 7 to thereby wash and remove deposited ash and rinsing waste water. The warm water W is uniformly sprayed by the adjustment of a orifice 11. Thus the heat transfer surface of the secondary preheater can be always kept clean to prevent the conductivity from reduction and the draft loss due to clogging from increase.
