Economic and environmental impacts of insulation in district heating pipelines

Publication year: 2011brbSource:/b Energy, In Press, Corrected Proof, Available online 24 August 2011brYusuf, Başoğul , Ali, KeçebaşbrThe determination of optimum thickness of insulation is often applied to energy technologies and building projects. In this study, the energy, economic and environmental evaluations of thermal insulation in district heating pipeline are discussed. The optimum insulation thickness, energy saving over a lifetime of 10 years, payback period and emissions of CO2, CO and SO2 are calculated for nominal pipe sizes and fuel types based on heating loads in Afyonkarahisar/Turkey. The life cycle cost analysis is used to determine the optimum thickness of the pipeline material in order to take into account the change in inflation that directly affect both…br Highlights: ► In this study, the economic and environmental evaluations of thermal insulation in district heating pipeline are discussed. ► Based on LCC analysis, the optimum insulation thickness, energy saving, payback period and emissions are calculated. ► About three times more energy saving results by making 200 mm nominal pipe instead of 50 mm. ► Considering the economical and environmental advantages, the geothermal energy is a better choice and then fuel-oil.
