ASSESSMENT OF RELATIVE HEAT LOSSES OF QUARTERLY HEAT NETWORKS FROM CTP-1 IN OSINNIKI, KEMEROVO REGION

Abstract

One of the main reasons for the undersupply of thermal energy supplied by the combined heat and power plant to consumers is the excessive (compared to the standard) heat losses in the city heating network. Although at present there is a method for determining the standard heat losses1 through thermal insulation structures, taking into account the material characteristics of the network, the temperature of the coolant and the environment, however, in practice this value is often accepted without sufficient justification within the range of 10 - 15% of the heat supplied from the source for average operating conditions over the heating period. Moreover, data on actual heat losses in different sections of the network, in block networks from various central heating stations, can differ significantly from the standard values, both upwards and downwards, which is associated with the actual state of the thermal insulation of the network, the tightness of the channel structures (penetration of groundwater into them) and a number of other factors.
