Description
Technical field
The present invention relates to thermal power generation unit and Material Field, be specifically related to a kind of system and method being suitable for novel high-temperature alloy material and parts carry out real stove checking.
Background technology
Thermal power generation unit, is the topmost forms of electricity generation of China, mostly adopts coal as fuel, and burning produces heat energy, and forms high-temperature steam, and driving steam turbine does work, and is converted to electric energy eventually through electromotor.
For improving unit efficiency, reduce coal consumption, reducing pollutant and CO2Discharge, develops high parameter, jumbo thermal power generation unit, is main development direction.At present, China's thermal power generation unit has developed into ultra supercritical from supertension, subcritical, supercritical, main steam temperature reach 600 DEG C, main steam pressure reach 30MPa grade.Future, by further to main steam pressure more than 35MPa, main steam temperature more than 700 DEG C advanced ultra-supercritical power generation technology development.
Along with improving constantly of thermal power generation unit steam parameter, the research and development of material become more and more important, and especially when main steam temperature is more than 700 DEG C, current material cannot meet requirement, it is necessary to the high-temperature alloy material that development is representative with nickel-base alloy, iron nickel base alloy.It can be said that problem of materials becomes the Main Bottleneck that thermal power generation unit develops to more high parameter already.
The research and development of new material, are a very long process, the checking of material and improvement, are to ensure that new material can carry out the key of engineer applied.But on the one hand, the associated materials test that current laboratory does, although the correlated performance data of material can be reflected, but high temperature and high pressure environment encountered in the middle of real stove with material after all and high-temperature steam burn into high-temperature flue gas corrosion condition there are differences, laboratory tests the material passed through, and is not offered as necessarily being amenable to live checking for a long time of Practical Project.On the other hand, the new material researched and developed also needs to by manufacturing the processing link such as welding, makes various parts, and the checking of associated components (especially large component), it is difficult in laboratory conditions carry out.It is therefore desirable to the high-temperature material adopted and parts to be carried out real stove verification experimental verification.
China was also carried out the hanging test of material, but method is to be placed directly within by test material in the middle of high-temperature corrosion environment (such as cigarette gas and water etc.), the decay resistance of test material itself, does not have comprehensive verification material and the parts function of properties under real fire bars part.
Therefore, how to design a kind of method, new type high temperature material and parts are carried out real stove verification experimental verification, can the various material of comprehensive verification and parts performance in real stove, it is ensured that associated materials and parts can be used in Practical Project；Real stove checking system can be simplified again as far as possible, reduce the workload manufacturing and building, utilize existing unit (host's unit) to complete checking work as much as possible；The impact on host's unit can also be reduced, it is prevented that checking test causes that host's unit is often forced to shut down, and is the problem that must solve simultaneously as far as possible.
