Embodiment Construction

[0036] The present invention will be described in further detail below through examples, and the following examples are explanations of the present invention and the present invention is not limited to the following examples.

[0037] The invention is suitable for debugging the steam turbine of a coal-fired unit, and the steam turbine is a supercritical, single-shaft, one-time intermediate reheating, two-cylinder, two-exhaust, air-cooled, steam extraction and condensing steam turbine. It is characterized by the use of digital electro-hydraulic adjustment system, easy operation, safe and reliable operation. Provide pressure adjustable heating network extraction, the pressure adjustment range is between 0.245Mpa(a) to 0.6Mpa(a) (when the pressure is lower than 0.36MPa, it is realized by throttling the extraction valve on the extraction pipeline); It can also provide non-adjusted industrial steam extraction with a pressure of about 0.9MPa or 2MPa at the same time. The high and m...

Abstract

The invention provides a complete-set starting commissioning test method and system for a coal-fired unit turbine, and the use safety of the coal-fired unit turbine can be improved. The method comprises the following steps that after transmission for a turbine complete-set starting commissioning test thermal signal and interlock protection test is completed, trial operating conditions of a system are checked and confirmed; an auxiliary device and the system are tested, cold starting testing is conducted on high and intermediate pressure cylinders of the turbine, and the corresponding relation between the lubricating oil pressure and the rotating speed is recorded; rolling parameters are recorded; a lubricating oil system is subjected to a pump switching test and a unit loading process warming-up test; a valve airtightness test and an overspeed test are conducted; the high and intermediate pressure cylinders of the turbine are started in a warm state; the high and intermediate pressure cylinders of the turbine are started in a hot state; the high and intermediate pressure cylinders of the turbine are started in an extremely hot state; a unit loading test is conducted; vibrating data in all stages of a unit are recorded; and a test of shut-down at sliding parameters is conducted. The system comprises a no-load and underload commissioning test module, a turbine on-load commissioning test module and a 168-hour full-load operating commissioning test module.

Description

technical field [0001] The invention relates to a method and system for starting and debugging a complete set of steam turbines of a coal-fired unit. Background technique [0002] A steam turbine is a rotary power machine that converts the energy of steam into mechanical work, such as the Chinese patent application number 201080046766.3. [0003] The steam turbine of the newly installed coal-fired unit needs to enter the start-up trial operation stage of the whole set of the unit after the trial operation of the sub-system is completed and qualified. Require. [0004] If the start-up and commissioning of the steam turbine of the coal-fired unit is improper, it will cause hidden dangers to the safe operation of the steam turbine generator set. Contents of the invention [0005] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art, and provide a coal-fired unit steam turbine start-up and debugging method and system that are ...
