Abstract:
1. A method for monitoring an industrial combustion process wherein image information represents a two dimensionally spatially resolved emission spectrum of a flame resulting from a combustion process in a combustion chamber, the method comprising: collecting the image information by an optical system having at least one micromechanical mirror, which is mechanically variably tiltable, such that the image information is scanned by the mirror; coupling the image information sequentially into at least two detectors, wherein the optical system includes a lens and a fiber bundle with optical fibers, and the at least one micromechanical mirror is arranged behind a window of the combustion chamber to separate the chamber from space in which the mirror is located; coupling the image information received from the micromechanical mirror into a first end of the fiber bundle as an optical signal; transmitting, via a second end of said fiber bundle coupled to the at least two detectors, the image information to the at least two detectors, each of the detectors being connected to a dedicated fiber and being sensitive to a certain frequency range for detecting organic radicals in order to characterize the combustion process in an analyzing unit, and providing measured parameters from the analyzing unit as input data to a control circuit, the control circuit controlling the supply of fuel or any other combustion material or combustion air.
