Improving Reliability

T-PRO* Fuel Firing System

GE can improve your boiler systems, from pressure parts and mills to low NOx burners. One of our solutions to improve your coal compartment when firing abrasive coal is the T-PRO Fuel Firing System.



The T-PRO Fuel Firing System lowers erosion and thermal stresses on units firing abrasive coal—stresses that can cause coal compartment components to fail. Among GE’s boiler service portfolio, the T-PRO Fuel Firing System’s state-of-the-art design and material selection is vital for equipment reliability, longer operation between outages, and shorter outage durations.

  • Increases coal nozzle and nozzle tip wear life
  • Improves reliability and availability
  • Increases operation time between outages and reduces outage duration
  • Reduces maintenance and repair labor costs
PV-PRO System

Performance, recovery, optimization

The PV-PRO System is an integrated Performance, Recovery and Optimization (PRO) system. Depending on your mill type, this upgrade includes an improved throat/air port, upgraded grinding zone and an adjustable static or dynamic classifier.



  • Less pressure drop
  • Improved efficiency and coal transport
  • Reduced pulverizer wear for extended operations
  • Better control of coal fineness
  • 18% lower mill motor power consumption with PV-PRO system installation (e.g. a U.S. power plant)
  • 39% lower mill differential pressure due to PV-PRO system installation
Plasma ignition

Flame stabilization and cold start

GE’s Plasma Ignition System reduces overall operating costs by improving low load operation and eliminating dependence on expensive oil or gas support fuels. The Plasma Ignition System is also designed to operate continuously, supporting low load operation.


The system produces high-energy plasma, which supports volatile release and subsequent coal ignition. The released volatiles ignite and produce further heat for increased fuel devitalization and full flame formation at the burner mouth.

  • Eliminate the use of oil/gas support fuels for flame stabilization when operating at low loads
  • Reduce coal consumption—the unit can maintain stable operation at lower loads without support fuel
  • Eliminate the need for a demineralized cooling water system
  • Greater system efficiency compared to direct current (DC) powered systems
  • Longer electrode life compared to DC systems, reducing material cost and labor required to replace electrodes
  • Eliminate oil/gas start-up system and O&M support
