Sažetak
The paper deals with the feasibility of using the radiation heat flux measurement as the diagnostic variable for the tube leakage detection system. The mathematical model based on the Monte Carlo zone method is used to investigate sensitivity of the radiative heat flux changes due to the water leakage into the furnace. Control volume based mathematical model is used to determine temperature, velocity and concentration fields. Radiative properties are determined by the three gray gases model. It was shown that the heat flux might be sufficiently sensitive diagnostic variable to be used in on-line monitoring of the large power plant boiler.
