 Operating plants achieve average annual NOx emissions of 25 – 30% of the EU limit using just process control and without the need for either Selective Non Catalytic Reduction (SNCR) or Selective Catalytic Reduction (SCR), whilst at the same time achieving very low CO and TOC emissions.The energy in the combusted syngas is converted into steam.Energos plants produce steam at lower temperature and pressure than modern waste incinerators, and thus achieve low energy-efficiencies compared to incinerators.
