OPTICAL SENSOR DEVICE FOR LOCAL ANALYSIS OF A COMBUSTION PROCESS IN A COMBUSTOR OF A THERMAL POWER PLANT

摘要

The invention concerns to an optical sensor device for local analysis of a combustion process in a combustor of a thermal power plant, in particular a gas turbine plant, wherein at least one wavelength selective optical element is exposed directly or indirectly to hot combustion gases being produced by said combustion process, said optical element provides an array of nano- and/or microcrystalline fibres which are created by use of shear flow crystallization.
