Abstract:

Taking the heatsupply network project of a thermal power plant for example, on the basis of heatload data analysis, the optimal diameter configuration scheme of the main pipe is selected according to the hydraulic calculation and heat loss estimation of the thermal pipeline. And through the comparison, technologic and economic analyze on 2 schemes which are laying overhead and laying underground, a suitable pipe laying mode is obtained.

Key words:
