Abstract:
Oxycombustion is a promising technique in terms of opportunities for improving performance of combustion plants. In this context, the use of oxycombustion in boilers can be a positive development, especially when it comes to the combustion of lower quality fuels. The paper aims to studying the NOx emissions from a natural gas fired steam boiler for different percentages of oxygen in the combustion air, of up to 100%. For this, an original model was developed for calculating the combustion with dissociation, which has been applied to the studied boiler.
