The JANSEN team of engineering professionals has established a reputation for unmatched technical expertise in the field of biomass, waste-to-energy, and chemical recovery boilers.

An Example of Poor Combustion

animation- Poor Boiler Combustion

Could the problem be:

  • Boiler performance below target capacity?
  • High particulate carryover?
  • Low boiler efficiency?
  • High carbon monoxide or TRS levels in the flue gas?
  • High levels of unburned carbon in the fly ash?
  • High moisture and/or high ash fuels?
  • High NOx emissions?
  • Inadequate water side circulation?

Are you in need of:

  • Burning more waste fuel?
  • Stack emissions compliance?
  • Increased steaming capacity?
  • Reducing fossil fuels burning?
  • Boiler and power systems startup?
  • Improved boiler efficiency?
