摘要:A s energy problem become more important, and nation require further intensify energy-saving work, coal-fired power plants begin to pay attention increasingly to the environmental protection and reliability. The study establishe a new method for the present coal-fired unit, that can overall evaluate environmental protection and reliability regularly. The running condition of a 600MW grade coal-fired unit in 2019 is take as an example for energy efficiency evaluation. The results prove that the method is simple andconvenient for the use. It can weigh the level of safety, energy saving, environmental protection technology and management for coal-fired power plants, and is important for advancing the firm’s core competence and long-term profitability.
