Item Selection of wavelengths for optoelectronic CO and O2 concentration analyser(Видавництво Національного університету "Львівська політехніка", 2002) Wójcik, W.; Manak, I.; Kotyra, A.; Smolarz, A.; Golec, T.; Kalita, M.; Komada, P.; Technical University of Lublin, Poland; Belarusian State University, Belorus; 3 Institute of Power Industry, PolandMeasurement of CO and O2 concentration near walls of a power burner allows limiting adverse side effects of the low-emission combustion. Conditions in which the measurements have to be made restrain the selection of wavelength used in absorption spectroscopy method. The article describes the absorption spectroscopy basics as well as the restrains that have to be considered when selecting the wavelengths.Item Optoelectronic method of estimation of chosen combustion parameters of an individual pulverised coal burner(Видавництво Національного університету "Львівська політехніка", 2004) Wojcik, W.; Golec, T.; Manak, 1.; Smolarz, 1.; Kotyra, A.; Komada, P.; Kalita, M.There are several tens of burners operating in a power boiler and their control based on averaged and delayed measurements is often not effective enough. The article describes attempts to obtain information about levels of emission of NOx and CO from the signals of the fiber-optic flame monitoring system developed in the Department of Electronics of the Lublin University of Technology. Artificial neural networks are used for estimation of emission. The article contains description of an object and the measurement system as well as results of research of nitrogen oxides and carbon monoxide modelling.Item Adaptive controlling of power boiler(Видавництво Національного університету "Львівська політехніка", 2004) Wojcik, W.; Kalita, M.; Smolarz, A.This paper presents research on adaptive control (AC) of combastion process in in¬dustry. Results were obtained from research conducted in laboratory combustion chamber with usage of Fiber Optical Measurement System (FOMS) with electronic block. Simulation proved that implementing AC and FOMS to burning process improves flue gasses parameters -direct measure of power boiler ecologic and economical quality of work.
