Title:
METHOD FOR CLEANING A HEAT EXCHANGER SURFACE AND SOLID BLASTING MEDIUM FOR CARRYING OUT THE METHOD
Document Type and Number:
WIPO Patent Application WO2001038815
Kind Code:
A3
Abstract:
The invention relates to a method for cleaning a heat exchanger surface (13, 37) that is exposed to hot gas containing fine dust. The heat exchanger surface (13, 37) is continuously or intermittently subjected to the action of a solid blasting medium (18a, 18b). According to the invention, the coarse ash that is produced when sludge is burnt in a furnace (6) and separated from the flue gas by coarse dust removal (17) is used as the solid blast medium (18a, 18b) in order to reduce erosion. Alternatively, a manmade solid resembling the coarse ash can be used.
