Burners / Injectors: Liquid fuels

Underport Burner

FT diesel oil injector has a unique atomizing solution that results in optimal heat transfer from combustion to the glass melt, one of the highest furnace efficiencies, and extremely low emission when replacing conventional burners.

technological flexibility

  1. three (3) different operation modes of atomizing: inside atomizing (most reliable and low in maintenance), outside atomizing, double (combination) atomizing
  2. adjustable double atomizing
  3. primary flame cone angle: 15 – 40°, depending on atomizing operation mode
  4. modular design of burner body and media supplying pipes adapts easily to constructional limits of furnace design

maintenance benefit

  1. atomizing gas parts remain free of oil
  2. clean environment around injector’s working areas
  3. applicable for low-quality fuels
  4. long-working cycles of the injector without maintenance
  5. long survival time when lacking cooling air
  6. atomizer is tolerant when missing oil preheating

scope of supply

  1. diesel oil injectors with the required capacity
  2. fully adjustable injector brackets
  3. stainless steel flexible hoses


  1. optimization of melting process using CFD simulation
  2. rental and maintenance contract
  3. port design optimization
  4. regular service during and after warranty period
  5. control panels & safety trains delivery
