| Title of the article | The influence of soil moisture on heat losses of pipes in the impassable channels |
| Abstract. | Flooding is a sensitive issue for many cities. 1108 cities of Russia flooded the earth 792 cities. Kazan, dissected by river valleys of the Kazanka River, the Knoxes, Kunderki, Salt, and a quarter of the territory is in a constant state of flooding. Geologists have concluded: the ground water is much higher – the groundwater level from 0 to 3 m. Such conditions can significantly affect heat losses of underground heat. The thermal conductivity of soil is not constant, it depends on the humidity. To calculate heat losses through insulated surface of heat pipelines for underground laying in impassable channels were selected two types of insulation: mineral wool plates on synthetic binding M-75 and mats from super thin glass fibers without binder. The analysis of heat losses through insulated surface of pipelines of thermal networks for different modes of operation of heat pipes with simultaneous wetting of the soil from 0 to 48 %. The dependence of heat loss from the moisture of the soil, a kind of thermal insulation and modes of operation. Comparison of the obtained results with normative values. |
