Taking a heat-supply system in Jinan City for investigated subject, the heat loss rate of steamheat-supplynetwork and hot water heat-supply network is analyzed and calculated.
Urban area heatsupplynetwork or, especially the medium pressure steam piping network, has tremendous difficulties in getting through and locating in downtown, and also the heat compensation.
城市供热管网,尤其是中压蒸汽管网,管线穿越市区,布置难度大,热补偿问题难于解决。

By the use of the pinch point technique the all LTS heat exchange network is optimized in design, and the new network process obtained does not need external supply of steam.
