Thermogravimetric–mass spectrometric study on the evolution of nitrogen compounds during coal devolatilisation

Emissions of nitrogen oxides during coal combustion are a major environmental problem. The chemically bound nitrogen in fuel accounts for up to 80% of total NOx emissions. In this respect, fundamental studies are needed to clarify the mechanisms and to identify the different species that are precurs...
