	1	Experimental and numerical investigations of the dry-low-NO_(x) hydrogen micromix combustion chamber of an industrial gas turbine显示文摘Combined with the use of renewable energy sources for its production,hydrogen represents a possible alternative gas turbine fuel within future low emission power generation.Due to the large difference in the physical properties of hydrogen compared to other fuels such as natural gas,well established gas turbine combustion systems cannot be directly applied for dry-low-NO_(x)(DLN)hydrogen combustion.Thus,the development of DLN combustion technologies is an essential and challenging task for the future of hydrogen fuelled gas turbines.The DLN micromix combustion principle for hydrogen fuel has been developed to significantly reduce NO_(x) emissions.This combustion principle is based on cross-flow mixing of air and gaseous hydrogen which reacts in multiple miniaturized diffusion-type flames.The major advantages of this combustion principle are the inherent safety against flash-back and the low NO_(x) emissions due to a very short residence time of reactants in the flame region of the micro-flames.The micromix combustion technology has been already proven experimentally and numerically for pure hydrogen fuel operation at different energy density levels.The aim of the present study is to apply and compare different combustion models for the characterization of the micromix flame structure,its interaction with the flow field and its NO_(x) emissions.The study reveals great potential for the successful application of numerical flow simulation to predict flame structure and NO_(x) emission level of micromix hydrogen combustion,help understanding the flow phenomena related with the micromixing,reaction zone and NO_(x) formation and support further optimization of the burner performance.

	2	Improvement study for the dry-low-NO_(x) hydrogen micromix combustion technology显示文摘The dry-low-NO_(x)(DLN)micromix combustion principle is developed for the low emission combustion of hydrogen in an industrial gas turbine APU GTCP 36-300.The further decrease of NO_(x) emissions along a wider operation range with pure hydrogen supports the introduction of the micromix technology to industrial applications.Experimental and numerical studies show the successful advance of the DLN micromix combustion to extended DLN operation range.The impact of the hydrogen fuel properties on the combustion principle and aerodynamic flame stabilization design laws,flow field,flame structure and emission characteristics is investigated by numerical analysis using an eddy dissipation concept combustion model and validated against experimental results.
