Abstract

The article presents an analytical evaluation of heat losses through the thermal in- sulation of pipelines, taking into account the actual operating conditions of thermal networks. Calculations confirmed a significant influence of the main operational factors on the increase in heat loss and the possibility of energy saving in heating networks.

Highlights

The considerable attention is given to a problem of savings of power resources [1]
Comparison of the thermal losses calculated in a program complex [8] with the losses received on the basis of natural tests on concrete sites of a thermal network, show convergence of results comprehensible to practice [9]
Values of the thermal losses calculated taking into account a condition of isolation and conditions of operation of heat conductors (Qcal.), are resulted in tab. 2 and on fig

Summary

Introduction

The considerable attention is given to a problem of savings of power resources [1]. A necessary condition of economically effective work of thermal networks is decrease in unproductive transport losses of heat through the isolated designs of pipelines. The purpose of this work is creation of the analytical tool for an estimation of losses of heat considering geometrical characteristics and ways of a lining of pipelines, and influence of supernumerary conditions of operation and a real technical condition of isolation on change of thermal losses.
