Abstract

The invention discloses a life-extension evaluation method for an overall equipment system of a thermal power turbine unit. By collecting and analyzing technical data such as relevant design, manufacturing, operation, overhauling, inspection and technical improvement of unit key components, the service safety and the residual life of the thermal power unit key components and equipment are comprehensively evaluated and analyzed according to the relevant standard, and the life situation of the power plant overall system comprising a boiler, a turbine, a generator and other system equipment is thoroughly grasped. Through careful planning, strict evaluation, and monitoring analysis and transformation strengthening, the thermal power unit is subjected to comprehensive life-extension evaluationby synthesizing the content of the aspects such as unit performance, the rotor and key component life, component material inspection and electrical and thermal elements. The newly-built unit investment can be avoided and saved, it is guaranteed that the overall system of the thermal power unit safely operates for a long time, accidents and disasters are avoided, and economic and social benefits are obvious.

Description

technical field [0001] The invention belongs to the field of power generation of a thermal power steam turbine unit, and in particular relates to a life extension evaluation method for an overall equipment system of a thermal power steam turbine unit. Background technique [0002] With the sustained and rapid growth of my country's economy, my country's power industry has developed rapidly. In recent years, the problem of lack of power load in my country has been completely solved, and the supply and demand of electricity are temporarily balanced or even affluent. However, due to the development of my country's economy, the national industrial structure is bound to be adjusted accordingly, which determines that the contradiction between power supply and demand will continue to exist, and the peak-to-valley difference in power consumption will also increase day by day. With the further deepening of my country's electric power reform, the establishment of the separation model ...
