Energos showcases commercially proven advanced thermal process at RWM show
UK based Energos will showcase its commercially proven advanced thermal process that provides a best practice alternative to both landfill and mass-burn incineration at RWM (stand 2380), 11 to 13 Sept 2012.
Energos designs, builds, operates and maintains small-scale local facilities capable of converting non-recyclable residual waste into sustainable, low emission energy. The Energos gasification technology produces low-cost heat and electricity, displacing fossil fuels while at the same time outperforming EU Emissions Standard (2000/76/EC).
The company has more than 500,000 hours of operating hours over more than 15 years at eight plants across Europe.
Energos’ patented gasification technology converts residual, non-recyclable waste into a gas by using the heat of partial combustion to free hydrogen and carbon in the waste.
Residual waste is fed into the gasification chamber, where it is converted into a syngas. This syngas is then transferred to a secondary oxidation chamber where it is mixed with air and recycled flue gas under tightly controlled conditions that ensures complete and efficient combustion resulting in reduced emissions in the flue gases. The upshot is ultra-low emissions, with the resulting heat recovered to produce steam and/or electricity.
A typical plant can generate 9MWe of renewable power from a variety of waste streams. This would equate to the output of 15 large wind turbines. Energos facilities are designed to complement recycling initiatives, at a small scale model that can exist at the heart of the community. As such, facilities can be sited next to energy consumers to optimise heat recovery, or in locations where a heat delivery or district heating system could be developed. Energos systems provide a local solution for local waste and eliminate the unnecessary transport of waste.
Energos’ newest gasification facility is at Borregaard Industries, Sarpsborg, in Norway. The 78,000 tonne per annum plant is owned by Norway’s leading power supplier, Hafslund Energy Recovery AS, who appointed Energos to design, build and commission the advanced thermal conversion facility.
The 32MWth double-line plant treats non-recyclable commercial and industrial waste and produces 256 GWh/a of high grade steam to displace approximately 22,000 tonnes of heavy fuel oil per annum. Since client handover, availability is running at more than 88%.
It supplements the similar sized Energos plant that has been delivering steam to Borregaard Industries since 2002, and will more than double the amount of heavy fuel oil that is displaced by the first plant. The new plant is reducing CO2 emissions by more than 50,000 tonnes per annum. The delivery of renewable heat from a secure source insulates local industry from rising oil and natural gas prices, helping to improve competitiveness and secure jobs.
