ANALYSIS OF THE CHP FUEL SUPPLY SYSTEM

https://doi.org/10.53360/2788-7995-2025-2(18)-49

Abstract

This article discusses the problem of reducing the energy efficiency of the fuel supply system at thermal power plants (CHP), associated with the use of coal of various brands and technological wear of equipment. The purpose of the study is to analyze the current state of the CHPP-1 fuel supply system in Semey, followed by the determination of heat losses and calculation of its efficiency depending on the type of coal used. The CHPP-1 in Semey was chosen as the object of the study, where the urgent task was the need to switch from project Kuznetsk coal to local coal from the Karazhyr mine. The article describes the technological scheme of fuel supply, gives the characteristics of the coals used, including a thermal calculation, including an assessment of losses at various stages, such as fuel quality, conditions of its storage and transportation, affecting the reliability of the system. The results showed that the use of Kuznetsk coal makes it possible to achieve a higher system efficiency (97.2%) compared to Karazhyrinsky coal (94.8%) due to its better fuel characteristics. Scientific value: Based on the analysis, the directions for improving the efficiency of existing systems are proposed. Practical value: The results can be used in the modernization of similar energy facilities.
