“…Since the pipelines have no thermal insulation, the heat losses are significantly higher than the normative values. [6][7][8][9][10] Energy efficiency and energy conservation represent an important aspect and are focused on activities such as reducing losses in heat and power generation. [11][12][13][14][15][16][17] The purpose of this paper is to determine the multiplication factor for the heat losses exceeding the normative values; to give recommendations for the reduction of heat losses in pipelines from recovery boilers.…”

The paper considers the calculation of heat losses through a non-insulated pipeline section of a waste-heat recovery system in a thermal power plant. The waste-heat recovery system of a power generator includes two circuits from each unit and the network water pipelines. The first circuit of the waste-heat recovery system is the high-temperature cooling loop of the generator gas reciprocating engine. The first circuit extracts heat from the engine cooling jacket. The second circuit of the waste-heat recovery system consists of the engine exhausts heat recovery boiler, heat exchanger (heated side), network plate-type heat exchangers, and a pipeline system. In the second circuit, the heat of the first circuit and the heat of the exhausts in the heat recovery boiler is extracted. The recovery boiler pipeline with no thermal insulation is routed on the roof of the thermal power plant. The research objective was to determine the actual heat losses through the non-insulated pipeline section and to compare the obtained data with the regulatory one.

The scope of operations of the branch where the survey was carried out is: transmission and distribution of heat and heating medium to consumers through heat supply networks, maintaining the proper quality and amount of thermal power and heating medium supplied, ensuring contractual activities with heat consumers, as well as control of compliance with the consumption regimes stipulated by contracts, ensuring payments from consumers for supplied heat and heating medium, development and implementation of measures ensuring maximum efficiency of heat supply activities. The purpose of the work performed is to determine the actual heat losses through the thermal insulation of the surveyed heating networks and to compare them with normative values. The article presents an analysis of materials on the heat supply system; test findings for actual heat losses in a heat supply pipeline; calculation of actual heat losses for each section and their adjustment to average annual operating conditions of the given heat supply network; comparison of calculation results with normative characteristics. The test findings are used in developing the output performance for the «Heat Loss» indicator and in setting of norms for operating heat losses. The heat supply source for the heat pipeline is the CHP-plant. The pipelines are routed above ground on high and low supports, as well as in crawl ways. The thermal insulation of the pipelines is mainly made of 50 mm blankets of mineral wool and is typical for heat supply networks. In overhauls of heat supply networks, polyurethane foam is partly used as thermal insulation.
