Abstract
Sposób wyznaczania odpowiedniej temperatury w szczególnych punktach wewnątrz komory spalania kotła wodno-rurowego na potrzeby procesu selektywnej niekatalitycznej redukcji tlenków azotu (SNCR) charakteryzuje się tym, że wykorzystuje się zależność lokalizacji stref o temperaturze 850 - 1100°C, w komorze spalania kotła, od temperatury w szczególnych punktach zlokalizowanych na ścianach kotła, w których to punktach zmiana temperatury jest ściśle związana ze zmianą rozkładu temperatury w kotle, a sam gradient wystarczająco duży do przeprowadzenia wiarygodnych pomiarów. Zestaw danych pomiarowych przedstawiony jest jako wektor, na który działa macierz przekształcenia liniowego. Macierz przekształcenia tworzona jest z wykorzystaniem schematów na jakich operują sztuczne sieci neuronowe i przekształca sygnał z pomiarów temperatury w szczególnych punktach na ścianach kotła na informację o temperaturze wewnątrz komory spalania kotła.The method of determining the appropriate temperature at specific points inside the combustion chamber of a water-tube boiler for the purposes of the selective non-catalytic reduction of nitrogen oxides (SNCR) process is characterized by the fact that the location of zones with a temperature of 850 - 1100 ° C, in the boiler's combustion chamber, is dependent on the temperature at specific points located on the walls of the boiler, at which point the change in temperature is closely related to the change in temperature distribution in the boiler, and the gradient itself is large enough to make reliable measurements. The set of measurement data is presented as a vector on which the linear transformation matrix acts. The transformation matrix is created with the use of diagrams on which artificial neural networks operate and transforms the signal from temperature measurements at specific points on the boiler walls into information about the temperature inside the boiler combustion chamber.
