摘要：Based on two 200MW three-cylinder and three-exhaust steam condensing units, the economic analysis of the unit connected pipe extraction, optical shaft heating and heat storage technology is carried out. Through these analyses, the coupling of the Optical shaft heating and the heat storage technology can not only give full play to the heating capacity of the unit, but also realize the "thermoelectric decoupling" and improve the flexibility of thermal power. Under certain external heat load demand, the power generation load can be reduced to 88MW when optical axis heating (only 44% of rated load). Besides, there is an optimal combination scheme. The annual policy subsidy is up to 424 million Yuan and the investment recovery period of the project is 5.6 years. The economic benefit of this project is obvious. It is recommended that the technology be applied to areas with a peak grid subsidy policy.
