| The aim of this paper is to estimate the corrosion
resistance of two types of U.S. boiler alloys, 1.25Cr-0.5Mo Sa-213 T11, 2.25Cr-1Mo Sa-213 T22
and one Russian pearlitic boiler alloy 12Cr1MoV under the influence of Estonian oil shale ash
from circulating fluidized bed (CFB) experimental facility at University of British Columbia
(UBC), Vancouver, Canada. The corrosion testing has been done on the laboratory apparatus in Thermal Engineering Depart- ment of Tallinn Technical University in the presence of Estonian oil shale ash from UBC CFB test facility in the temperature interval from 500-580 °C lasting 500 hours. The results obtained can be used in the evaluation of high-temperature corrosion intensity during the observed interval. |
