The aim of the work is a theoretical study of the efficiency of heat supply based on a soft-ware 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 sched-ules 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; construction of ini-tial, reduced and extended temperature schedules and schedules of delivery water consumption; de-termination of optimal energy costs and heat-transfer agent costs. The most important of the results achieved is the carried analysis of the energy and economic efficiency indicators 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 initial 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 significant. The significance of the obtained results lies in the fact that they allow calculating the energy effect in the form of fuel savings at CHPPs compared to their operation with the design temperature 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. |
