一、概述 供热网是城镇或工厂企业里把生活及生产所需要的热水或蒸汽分送到各个用户的管道网络。由于热水比蒸汽易于制备和长距离输送;现在的大热网,除用户要求供给蒸汽时外,一般都是供送热水的。本文中使用“供热网”或“热网”这个词时,指的都是供送热水的管道网络。 依靠建设供热网,可以把千家万户需要的热水集中在设备优良技术先进的少数供热厂里制备,分散的家用烧水小火炉曾是污染
I. Overview A heating network is a pipeline network that distributes the hot water or steam needed for life and production to each user in a town or factory. Because the hot water is easier to prepare than the steam and it is transported over long distances, the current large heat network is generally supplied with hot water except when the user requests steam supply. The term “heat supply network” or “heat supply network” is used in this article to refer to the network of pipes supplying hot water. Relying on the construction of a heating network, the hot water needed by thousands of households can be concentrated in a small number of heating plants with advanced equipment and advanced technology. The scattered household water-fired small stove was once polluted.
