Coal’s Revival Part II: Turning Ash Chemistry into Measurable Boiler Performance
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 […]

Typical Causes of Slagging and Fouling Problems in Boilers
Boiler slagging and fouling, and the resulting frequent operation of sootblowers, are some of the major operations and maintenance factors that can negatively affect power plant reliability and efficiency. Boiler slagging and fouling are among the most common causes of maintenance headaches at coal-fired power plants. Though you cannot totally eliminate the problem, following proper […]
