A review.  This poster paper presents an overview with refs. of the Åbo Akademi full-​scale boiler ash behavior measurement database.  The database contains data from some 20 full-​scale boiler measurement campaigns during which the ash behavior in the boiler has been monitored identically.  The measurements have been done in 3 different bubbling fluidized bed boilers and 2 circulating fluidized bed boilers during 11 different campaigns.  For comparison data from 2 pulverized fuel fired boilers as well as from 2 grate fired boilers have also been included.  The data collection includes conventional analyses of the fuels or fuel mixes used during the measurements, ash deposition measurements performed with the air-​cooled probe technique, chem. analyses of the collected deposits (front and back side sep.)​, chem. analyses of the boiler fly ashes, and recordings of chosen relevant boiler operation parameters such as boiler load, air-​distribution, and flue gas temps.The poster paper presents ash deposition data, so-​called rate-​of-​build-​up values (RBU g​/m2h) as a function of fuel mix, probe surface temp., and boiler type.  The poster also presents compositional data of the collected deposits such as the chlorine content as a function of fuel mix and probe surface temp.
