Research on the Opportunities to Reduce the Operational Cost of the Thermal Power Facilities

Abstract

The problems of efficiency and reliability of the heat power engineering equipment, the productivity of using make-up water and systems for supplying and dosing chemicals are analyzed. One of the ways to improve the technological process of preparation makeup feed-water has been developed, by simultaneous dosing of several reagents to reduce the aggressive effect of water on the inner surfaces of the equipment of heat power facilities, to ensure an anti-limescale and anti-bacterial regime, which significantly reduces operating costs. The Chemical Injection Package with the reagents for various purposes is proposed fitting together with the existing water treatment scheme. As a result, this will lead to a decrease in the corrosion intensity; the internal deposits formation prevention and the destruction of the bacteria that cause ulcerative sub-sludge corrosion of pipelines and equipment. For the thermal power facilities equipment reliability and efficiency, as well as for ensuring its optimal water-chemical regime, a scheme for corrective treatment of the make-up water for heating networks was developed and implemented. It is proposed to use chemical reagents to achieve the formation of thin protective films on the surface of metals, which will prevent the aggressive effects of water. To reduce operating costs when servicing thermal power facilities and operational reliability due to the provision of an optimal water-chemical regime, a scheme for corrective treatment of the make-up energy water used in the heating networks was developed and implemented.
