Specific NOx briefing

• Max150 mg/Nm3 (yearly average) for PC hard coal boilers put in operation latest 7 January 2014. The BAT levels accepted – the lower range – state that: • <85mg/Nm³ is achievable for lignite-fired boilers using the SCR DeNOx technique. NOTE: the level of 85mg/Nm³ is the maximum emission level expected when SCR is installed

Oxy-fuel Combustion Systems for Pollution Free Coal Fired

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Jupiter Oxygen's patented oxy-fuel combustion systems1 are capable of economically generating power from coal with ultra-low emissions and increased boiler efficiency. Jupiter's system uses pure oxygen as the combustion agent, excluding air and thus nitrogen, concentrating CO2 and pollutants for efficient capture
