SIMULATION OF THERMAL STATE AND EXPERT EVALUATION OF HEAT LOSSES OF HEATING MAINS PIPELINE BASED ON THE ACTUAL CONDITIONS OF THEIR INSULATION
An analytical solution of the mathematical model for determining the actual heat loss through the insulation of pipelines with a damage of the insulating layer is proposed. The algorithm for determining the resulting heat flow for the entire pipeline with damaged insulation is constructed, taking into account the share of damages and their quantity. This allows to spend the expert evaluation of heat loss. The zones of influence the damaged area on the value of heat loss are found, the coefficients of increase of heat flow are set.
