ASSESSMENT OF RELIABILITY OF TRANSPORT OF THERMAL ENERGY IN HEAT SUPPLY SYSTEMS OF CITIES
We evaluated the reliability of heat supply system of the city the population is about 90 thousand inhabitants, located in the Volga Federal district, in which the main source of heat is a small CHP plant with a connected load 153,5 MW and heat supply for the four heating mains in diameter 350-1000 mm with temperature schedule 110/70 0C. The results of calculation of parameters of the flow of failures and the probability of failure-free operation of heat pipes on the main heating mains from the power plant to the centers of consumption.
