Vujtsik V. Methods of control of heat parameters of combustion processes

Thesis is dedicated to elaboration of methods and means of control of processes of combustion in industrial energetic boilers. The basic parameters that characterise this process are pulsation of flame and intensity of its lighting that are proportional to the temperature. Methods of control of products of combustion (SO2, NO2) are elaborated. Methods for digit service conditions based on light guide technique and new methods of signal analysis (neuron network, wave transformations) are elaborated. These methods have considerable advantages against Fourier transformation, especially in the conditions of stochastic changes. Analysis and investigation of choice of light guides, constructions of measuring heads and measuring circuits for measuring systems of processes of combustion are done. Models of processes of control are elaborated. The regularity of change of information of heat values at combustion is revealed. The optimization of light guide sensors by method of finite elements is done. The ration al construction of sensor is chosen by simulation of six forms. For measuring of pulsation and intensity of flame lighting two measuring channels (logarithmic LOG100 and linear OP07) were used. This provides the temperature and pulsation measuring with the 0.1% error. The results are implemented at thermoelectric power stations.
