Thermal power engineering relies on fossil fuels (such as coal and natural gas), converting their chemical energy into thermal energy through combustion, and then successively into mechanical energy and electrical energy. It is a systematic engineering discipline and a core component of national energy infrastructure. It covers the entire lifecycle from project initiation and design to construction and operation and maintenance. The core consists of the three main units—boiler, turbine, and generator—together with auxiliary systems. Characterized by high technical intensity and strong reliability, it provides stable electricity for industrial production and public welfare. At present, it is transitioning toward cleaner, smarter, and low-carbon development, supporting the achievement of the “dual carbon” goals.
