Solutions by TERMOOPTIM - Enhanced solutions for lignite grinding and lignite firing equipment

TERMOOPTIM offers optimized technical solutions to enhance the lignite grinding and lignite firing processes in the direct firing system or with pulverized coal concentrator used in power plant boilers:

• equipping the fan beater mills with supplemental retention beater stage
• introducing dust concentration devices with reduced flow resistance
• introducing low NOx pulverized coal burners

These solutions can be implemented individually or combined depending on customer’s preference.

Due to the optimizations made to the design solutions as well as the functional parameters for the assembly mill/concentrator-classifier device/pulverized coal burner, the following advantages in boiler’s operation have been proven:

• increased pulverized lignite fineness
• increased lignite combustion stability
• reduced NOx emissions
• reduced combustion chamber pulsation
• reduced slagging in mill tower suction
• reduced unburnt residue in the combustion chamber
• 1-2% increase in boiler thermal efficiency.
