TO THE ISSUE OF EFFICIENCY AND ECOLOGICAL SAFETY OF HEAT POWER SYSTEMS ^{[№ 12 ' 2017]}
Centralized heat supply systems in different regions operate under conditions of potential risk. The coolant is mainly water, which leads to various emergency and emergency situations with negative environmental and economic consequences. The condition of objects of various generating systems and installations is directly connected with reliable power supply and ecological safety of the object, region, country. Modern energy-saving systems consider the use of a coolant with a lower temperature (+40...+ 50 °C). This method shows the negative side: the lower the temperature of the coolant, the greater the size of the equipment. Insulation does not withstand temperatures above 130 °C, as a result of thermal degradation it darkens, shrinks and absorbs water. In the presence of water, polyurethane foam releases an acid, under which the pipelines are intensely corroded. The water used is subjected to special treatment. In the Orenburg region, SES is being actively built, which should improve the reliability of the electricity supply system, gradually reduce the price of electricity and the level of the environmental crisis. Commissioning of solar generation in the territory of the Orenburg region will save 9 million m³ of gas per year. To increase the efficiency and environmental friendliness of heat-and-power systems, research and development is needed that will enable the transition to new environmentally friendly and affordable energy sources. Their application will contribute to the conservation of natural resources, which should become the main principle of the formation of ecological knowledge and ecological culture for modern society.
