In the EU, emissions from energy from waste plants are largely reduced by applying the Waste Incineration Directive with its limit of 200mg/m3 s for NO. x emissions. The need for further improvement is reflected by new German legislation effective as of 27 January 2009, requiring 100mg/m3 s. Other countries are expected to follow this example due to the national emission ceilings of the Gothenburg protocol and the concluding EU directive 2001/81/EC. On the other hand, an increase in energy efficiency will be encouraged by the EU Waste Framework Directive. This is why there is a need for new technologies that make it possible to reconcile both requirements: reduced emissions and increased energy efficiency. A new process combining the internal recirculation of flue gas with ammonia or urea injection in order to achieve less then 80mg/m3 s of NO. x is described. Important additional features of the process are an R1 efficiency above the required 0.65 of the EU Waste Framework Directive even with standard steam parameters of 40. bar/380 °C as well as low ammonia slip in the flue gas at the boiler outlet of below 10mg/m3 s. © 2010 Elsevier Ltd.
