Briefings

A POWER Magazine field demonstration on a 500-MW coal unit tested targeted fuel chemistry to reduce slagging and fouling. The trial achieved approximately 50% lower superheater spray demand and 53% lower reheat spray demand under comparable conditions, alongside reduced air preheater inlet gas temperatures and improved combustion flexibility.

Key points

• A POWER Magazine field demonstration on a 500-MW coal-fired unit tested targeted fuel chemistry to reduce slagging and fouling.
• The trial achieved approximately 50% lower superheater spray demand and 53% lower reheat spray demand under comparable conditions.

Context

POWER Magazine published a field demonstration on a 500-MW coal unit showing how targeted fuel chemistry can mitigate severe slagging and fouling while delivering measurable operating benefits including reduced spray demand and improved combustion flexibility.

Limitations

Evidence is limited to a single 500-MW field demonstration; specific NOx reduction figures are truncated; trial conditions are described as comparable but not identical to baseline; no author names or specific dates beyond publication date are provided.
