In this work the effects of fuel parameters and under grate flue gas recirculation (FGR) are investigated when applying staged air combustion of solid fuel for the purpose of NOx reduction. In addition to temperatures, residence times and primary and overall excess air ratio, the fuel-N content and ...

In the present work, transient CFD simulations of full wood log combustion cycles have been performed to study the time dependent behavior in cast iron and soapstone wood stoves. A model for the gas release is developed and implemented. The gas release model takes into account that the fuel gas rele...
