Modelling of heat transfer by radiation

Heat transfer by radiation is something you experience everyday: when walking outside in the sun or when cooking your diner. This thesis provides understandable models of the role that radiation plays in the transfer of heat. By studying literature we developed a mathematical basis for the heat transfer model, where we discuss diffusive,...

Electric preheating of combustion air: Design of a cost-effective and compact electric combustion air preheater for the LSV® burner

This thesis report discusses the design of a cost-effective and compact electric combustion air preheating for the LSV® burner. The industry has a complex problem to solve and an important role to play during the energy transition, that is needed because of global warming. Many industrial processes use heat generated by the combustion of fossil...

Experimental and numerical study of MILD combustion in a lab-scale furnace

Mild combustion in a lab-scale furnace has been experimentally and numerically studied. The furnace was operated with Dutch natural gas (DNG) at 10 kW and at an equivalence ratio of 0.8. OH∗chemiluminescence images were taken to characterize the reaction zone. The chemiluminescence intensity is relatively low compared to conventional flames...

Furnaces with multiple ?ameless combustion burners

In this thesis three different combustion systems, equipped with either a single or multiple ?ameless combustion burner(s), are discussed. All these setups were investigated both experimentally and numerically, i.e., using Computational Fluid Dynamics (CFD) simulations. Flameless combustion is a combustion technology capable of accomplishing the...
