Energos Technology
The Energos system includes a close coupled combustion stage which, as configured, uses all the syngas in the combustion stage. It is thus not able to produce syngas for external use and therefore sometimes categorized as two-stage combustion. The process enables improved control of the combustion to minimise the formation of combustion related emissions such as oxides of nitrogen (NOx), Carbon Monoxide (CO) and Total Organic Carbons (TOC). 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. As a CHP or heat delivery plant, the cycle efficiency is approaching 85%. One such example is the recently constructed Sarpsborg 2 plant, which provides process steam to the Borregaard Chemical Plant, directly displacing heavy fuel oil.
The Isle of Wight plant debuts a new furnace design for the Energos process aimed at increased combustion efficiency, dust removal and enabling less interruptions and downtime than the earlier design

Famous quotes containing the word technology:
“The real accomplishment of modern science and technology consists in taking ordinary men, informing them narrowly and deeply and then, through appropriate organization, arranging to have their knowledge combined with that of other specialized but equally ordinary men. This dispenses with the need for genius. The resulting performance, though less inspiring, is far more predictable.”
—John Kenneth Galbraith (b. 1908)
