Coal Drying Technology

Low-temperature coal drying technology that improves fuel efficiency and reduces emissions in thermal power plants.

TABi Energy's Waste Heat Integrated Coal Drying technology converts low-grade, unused waste heat into measurable fuel quality and efficiency gains, specifically targeting high-moisture lignite and sub-bituminous coals. Developed from laboratory-scale research and successfully deployed at utility scale, the system improves plant performance without adding fuel consumption or increasing emissions.

Proven Benefits

Field data and operational experience demonstrate:

  • Significant coal moisture reduction
  • Direct increase in coal calorific value
  • Improved combustion stability and boiler efficiency
  • Reduced flue gas losses and auxiliary power demand
  • Lower CO₂ and pollutant emissions per MWh

Measured results consistently confirm a strong inverse relationship between moisture content and calorific value, validating the impact of integrated drying on overall plant efficiency.

Why Waste Heat Integration?

Unlike conventional dryers, TABi Energy's approach:

  • Utilizes existing waste heat sources
  • Requires no additional fuel firing
  • Minimizes operational complexity
  • Enables scalable, site-specific integration

The result is a low-CAPEX, high-impact solution with fast payback.
