Coal’s Revival Part II: Turning Ash Chemistry into Measurable Boiler Performance
by Contributed Content from POWER Magazine on (#79G7R)
A field demonstration on a 500-MW-class coal-fired unit shows how targeted fuel chemistry can mitigate severe slagging and fouling while delivering measurable operating benefits-including approximately 50% lower superheater spray demand, 53% lower reheat spray demand during comparable trial conditions, lower air preheater (APH) inlet gas temperatures, improved combustion flexibility, reduced selective catalytic reduction (SCR)-inlet NOx [...]
