Estimation of fouling profile in boiler tubes using inverse heat transfer method, laminar flow
One of the effective factors in decreasing the efficiency of boilers during the operation period is sediment. The sediment sits as a layer on the boiler's heat transfer surfaces and reduces the boiler's thermal efficiency due to the thermal resistance it creates. For this reason, it is very important to determine the amount of sediment and to accurately measure it in boiler pipes.In this paper, it is assumed that no information is available on the distribution of sediment in boiler pipes, so the sediment profile is estimated using temperature simulation on the inner wall of boiler pipes as well as conjugate gradient method. In this method, the error rate was calculated by estimating the function of multi-criteria sediment profile , which indicates the high accuracy of the conjugate gradient method in sediment estimation. The amount of sediment exceeded a specified value.
