热力管道de保温节能

Heat Preservation of Heat Pipes for Energy Conservation

本文通过分析化工企业热力管网保温状况，提出管道改造重点按照先高温，后中温；先主，后支：先室外、后室内的原则，从而达到节能降耗的目的。

After analysing the actualstate of the heat preservation of heat-sup-ply network in the chemistry industries,this paper puts forward the principle of the innovation of the heat-supply network:thatis,to innovate part of high temperature first and then that of medium temperature:mainpart first and then the subordinate part:part outdoors first and then that indoors.In this way the purpose of power-consump-tion reduction can be abtained.
