| description | The aim of the work is a theoretical study of the efficiency of heat supply based on a software package that includes mathematical models of a real CHPP, a real heating network and real heat consumers with a high share of hot water supply load using extended and reduced temperature schedules of heating regulation. The set aim is achieved by solving the following problems: choosing a method for calculating various schedules of regulating heat supply from CHPPs; con-struction of initial, reduced and extended temperature schedules and schedules of delivery water consumption; determination of optimal energy costs and heat-transfer agent costs. The most im-portant of the results achieved is the carried analysis of the energy and economic efficiency in-dicators changes during the transition from the traditional to lowered and extended schedules of heat-supply system regulation. The total fuel savings at CHPP during the transition from the ini-tial design temperature schedule with a maximum delivery water temperature of 150°C to the most energy efficient schedules reaches about 2%, which should be recognized as very signifi-cant. The significance of the obtained results lies in the fact that they allow calculating the ener-gy effect in the form of fuel savings at CHPPs compared to their operation with the design tem-perature schedule. It is shown that the use of these technologies will increase the efficiency of district heating that will ensure a reliable and high-quality supply of heat energy to consumers and reduce its cost. |
