Analysis of the Boiler Losses which Affect the Performance Efficiency of the Production System in Mahananda Dairy

This paper deals with determination of the failures causes of boiler in Mahananda Dairy plant. Due to frequent fractures of supporting tubes occurring always at the same location in the furnace and the ensuing reduction of the plant availability as well as substation financial losses, there was an urgent need to resolve the problem. Standard investigation procedure was applied on samples removed from upward inclined section of supporting tubes system. Several literatures suggested that material characteristics affected the life of a material after receiving pressure repeatedly which lead to failure. The aim of this study is to find the best formula in anticipating the occurrence of repeated failures of a tube based on pressure aspect, mainly in steam power plant. Results show that Analysis of various papers mentions failure caused by several interrelated factors. Factors that causes a failure was discussed due to corrosion and overheating, while the pressure factor is not a main factor causing a failure. The best formula for determining the failure analysis in terms of stress are material selection, visual observation of the failure form, knowing the location of the failure.
