[Abstract]:The circular economy project of Tianjin Bei Jiang Power Plant is the first batch of state-level circular economy pilot projects approved by the State Council. The project makes full use of the resources in Hangu District, and better solves the problem of efficient and clean power generation, water saving, and land saving. A series of problems, such as desalination of seawater, comprehensive utilization of concentrated seawater and fly ash, have formed a circular economic industrial chain of "electric water salt land", which is regarded as the "northern Xinjiang model" for the development of circular economy in electric power industry. After the project was put into production in 2009, it provided 12 billion kilowatt-hour electric energy and 65 million tons of fresh water to the society every year, which provided important energy support and fresh water resources guarantee for the development and construction of Tianjin and Binhai New area. The purpose of this paper is to sum up the experience of the first stage of the cycle economy project of the North Xinjiang Power Plant, to study and put forward the plan of the second phase of the project and to carry out the preliminary feasibility study, so as to provide decision support for the preliminary work of the second phase of the expansion project of the North Xinjiang Project. On the basis of summing up the experience of the first phase circular economy project in Northern Xinjiang, this paper creatively puts forward the plan of the second phase expansion project: continue to adopt the integrated development mode of "electricity, water, heat, salt, chemistry and materials", which takes power generation as the leading factor, "electricity, water, heat, salt, chemistry and materials". Planning and construction of two 1 million kilowatt ultra-supercritical generating units, with a daily output of 300,000 tons of seawater desalination units, an annual production of 1.5 million tons of refined salt and 300000 tons of salt chemicals, a comprehensive utilization project of concentrated seawater, and an external heating supply of 12 million square meters. Supporting the construction of comprehensive utilization of fly ash, and pilot projects to reduce carbon dioxide emissions. After putting forward the second phase project plan, this paper analyzes the electric power system, the heat load analysis, the resource utilization and the energy saving, the investment estimate and the financial evaluation, the risk analysis, the economic and the social benefit appraisal, and so on. A preliminary feasibility study on the second phase circular economy project in Northern Xinjiang was carried out. It provides important program planning support and investment decision support for the preliminary work of the second phase of Northern Xinjiang. According to the planning plan and preliminary feasibility study conclusion of this paper, the State Energy Administration has issued a document agreeing to carry out preliminary work, and the preliminary work such as project research, environmental impact assessment, access to the system and land use prehearing has been carried out in a comprehensive manner. It plans to obtain approval from the National Development and Reform Commission in the second half of 2013 and start construction in 2014.
