Abstract:
Based on the principle of optimization with consideration of the energy loss cost per unit length of heat-supply pipeline and the annual investment apportioned cost, induces the formula for calculating the economical insulating layer thickness of energy loss. Based on the principle of exergoeconomics and the exergy loss cost per unit length of the pipeline and the annual investment apportioned cost, induces the formula for determining the economical insulating layer thickness of exergy loss. Performs calculation and analyses for practical pipelines. Provides the formula of economical insulating layer thickness of exergy loss for plane insulation design.
Keywords:thermal pipeline, insulation, economic thickness, energy loss, exergy loss
