PURPOSE: A method for designing insulation of pipelines and equipments of thermal power plant equipments is provided to minimize an error for calculating heat radiation quantity of the pipeline, and to facilitate the calculation. CONSTITUTION: A pipe and the insulation are determined by considering an operating pressure/temperature and a flow limit of a pipe(S12). Physical values of the determined pipe and data of the insulation are inputted to a calculating sheet written by the Excel(S14). A thickness of the insulation is determined/inputted to the calculating sheet. A heat transfer resistance, a heat dissipation quantity per unit length, a surface temperature of the insulation, and the heat radiation quantity of entire pipeline are calculated/displayed depending on the physical values of the pipe and the thickness of the insulation(S22). |
