Analysis of Heat Loss from Insulation Deterioration by Applying Value Engineering Technique for a Boiler of a Thermal Power Plant

This paper presents an analysis of the heat Loss from insulation deterioration by applying value engineering for a boiler of a 340 MW thermal power plant under operating 29 % Installed capacity . To analyze the loss of heat from insulation deterioration of the boiler, Value job plan six steps of Society of American Value Engineers International ( SAVE ) is applied for the thermal power plant as the following : 1 ) data and information collection, 2 ) function analysis, 3 ) creative, 4 ) evaluation, 5 ) development and 6 ) presentation . According to the research, the results show that there is a 5,295,280 . 21 MJ thermal loss, in case of corrective measures . Replacement insulation can reduce heat loss by 4,510,644 . 60 MJ at 100 % output factor or 85 . 18 % and reduce heat loss by 2,119,551 . 90 MJ at 46 . 99 % output factor or 40 . 03 % and the insulation temperature up to 60 °C . The payback period is found to be 0 . 32 years . Moreover, this research methodology can be applied to other power plants in the future .
