METHOD AND SYSTEM FOR CLEANING HEAT-EXCHANGING SURFACES OF A CIRCULATORY REGENERATIVE HEAT EXCHANGER

摘要

According to known methods for cleaning the heat-exchanging surfaces of a circulatory regenerative heat exchanger (1) grave damages due to thermal deformations occur when the heat exchanger (1) is cleaned during its operation. The aim of the invention is to provide a method and a device that allows to clean the heat exchanger without the above-mentioned problems and in a satisfactory manner. To this end, the cleaning agent supplied by the nozzles (9) is kept away from the tangential walls (17). Once the cleaning agent is discharged from the storage material (19), agents (15) for atomizing the cleaning agent are used.
