Growing attention had been drawn to the use of biomass as fuel for electricity generation in China. However, as a fairly new imported technology in localization, it had met serious problems with slagging and fouling of the super-heaters. The slag deposit on the first super-heaters in a biomass boiler was characterized by XRD, SEM-EDS and XRF to make clear the reason for the slag deposit. According to the results, alkali metal such as K, Na and Ca were predominant in the slag deposit. NaCl and KCl in the form of halite and sylvite were confirmed by XRD. |
