Experimental development of CO2, SO2 and NOx emission factors for mixed lignite and subbituminous coal-fired power plant

► New EFs (emission factors) for CO2, SOx & NOx in a coal-fired power plant from experimental data. ► An estimation of the emissions from coal mixtures using pure coal EFs was developed. ► CO2 and SOx can be estimated from standard pure coal EFs (energy-based mixtures). ► NOx cannot be derived from pure coal EFs, as it depends on the combustion conditions.
