Fuel Tech Chemical TechnologiesChemical Technologies

Our Chemical Technologies solutions are focused on boiler efficiency improvements to reduce Greenhouse Gases (GHG) by controlling slagging, fouling, and corrosion, along with reducing hazardous air pollutants including mercury, acid emissions, and fine particulate matter formation (PM2.5).

Chemical Injection Programs Address:

  • CO2
  • Mercury
  • HCl Emissions
  • Slagging
  • Fouling
  • Corrosion
  • Opacity Acid
  • SO3 & Acid Plume Issues
  • Loss on Ignition (LOI)
  • Ammonium Bisulfate (ABS)

Programs Offer Numerous Operational, Financial and Environmental Benefits to Owners of Boilers, Furnaces and Other Combustion Units

Availability and Reliability Gains

Gains are reflected in the incremental degree to which power generators avoid service interruption or degradation as a consequence of the failure or deterioration of a system component. TIFI® Targeted In-Furnace Injection™ programs can reduce: derates arising from slag shedding, derates due to less sootblowing and burner anomalies, water lance/water cannon usage, forced outages due to fewer repairs, the number of planned outages, and downtime for outages due to less maintenance, including deslagging.

Efficiency Gains and Heat Rate Improvements

There are sizable benefits arising from improved energy efficiency and heat rate improvements from the fuel combustion process. TIFI programs increase MW per unit of fuel input (or constant MW with lower fuel consumption), reduce power requirements for Induced Draft/Forced Draft (ID/FD) fans, reduce sootblowing requirements, reduce unburned carbon and LOI in ash, reduce furnace exit gas temperature (FEGT), reduce operating O2, and reduce furnace CO and stack CO2 emissions.

Fuel Flexibility

Plants need the flexibility to burn lower quality, lower cost fuels in their combustion units. Chemical Technology programs can mitigate the effects of slag-forming impurities such as sodium and iron, which are present to varying degrees when burning economical coals, such as Powder River Basin (PRB) and Illinois Basin (ILB). Higher-sulfur coals, such as those found in the ILB and certain Eastern coalfields, can also be made less problematic with a TIFI program, which can be designed to mitigate the adverse effects of SO3 formation in power plants utilizing Selective Catalytic Reduction (SCR) systems to reduce NOx.

Maintenance Benefits

Our suite of Chemical Technology programs offer numerous opportunities for operating cost reductions, including labor cost savings, and avoided equipment replacement. These programs can offer the following: reduced cold end corrosion in the air pre-heater, stack and ductwork, reduced high-temperature tube repairs/replacements (corrosion/erosion), increased life of super heater pendants, reduced clinker formation, elimination of equipment damage from falling slag, reduced air pre-heater fouling, reduced fireside cleaning expenses, including explosives, reduced water/air treatment costs (less steam/air for sootblowing), and reduced sootblower maintenance (manpower and parts).

Environmental Improvements

A variety of Chemical Technologies can help mitigate the effects of mercury, HCl and SO3. In addition, Particulate Matter (PM2.5) and CO2 can be reduced.

All of our programs include custom designed, state-of-the-art pumping/injection equipment and on-site technical support. Our programs are monitored, serviced, and supported worldwide by our sales and project execution teams. Performance is monitored using Return on Investment (ROI) as the foundation for program success. Customers using our TIFI Technology have achieved ROI of as much as 400% or greater by identifying and quantifying the relevant operating benefits described above.
