本文讨论了流化床燃烧的N2O和NO排放量的测定实验工作的结果。首先，进行了研究，以测量在燃烧过程中的烟煤和焦炭从相同的煤制备的NO和N2O的量。其次，研究了挥发分在煤热解过程中的燃烧，并测定了N2O和NO的排放量。同时对挥发物中HCN和NH3进行了分析。从我们的研究结果，更好地理解的问题，均相反应与非均相的N2O的形成。
This paper discusses the results of the experimental work undertaken to determine the N2O and NO emissions from fluidised bed combustion. First, studies were carried out to measure the amounts of both NO and N2O formed during the combustion of bituminous coals and that chars prepared from the same coals. Second, the combustion of the volatiles released during the devolatilisation of coals was investigated and the N2O and NO emissions were measured. The analysis of HCN and NH3in volatiles was also undertaken. From our results, a better understanding of the issue of homogeneous reactions versus those of heterogeneous for the formation of N2O is achieved.
