Description

Technical Field

[0001] The present invention relates to the field of thermal power technology, and in particular to a boiler heating surface diagnosis and early warning method, system and a three-dimensional visualization management platform. Background Art

[0002] The heating surface of a boiler usually refers to the metal surface area on one side that contacts the flame or flue gas, and the other side that contacts water or heat transfer oil. The heat exchange of the boiler is carried out through such a metal surface area. The larger the heating area, the larger the boiler capacity, and vice versa. However, due to the high temperature and high pressure environment generated by combustion, as well as factors such as material aging and scaling during long-term operation, the heating surface of the boiler is prone to wear and damage during use, thereby affecting the safe and stable operation of the boiler.

[0003] The Chinese patent with publication number CN103196128A discloses a method for designing the heating surface of a power plant boiler. The method is only applicable to the case where the flue gas temperature deviation is fixed. In the first step, the flue gas temperature deviation coefficient of each screen is determined according to the flue gas side temperature deviation curve on the same section; in the second step, the steam deviation curve is determined according to the given header size and the introduction and extraction method of the heating surface pipes from the header to obtain the steam deviation coefficient of each screen; in the third step, the flue gas temperature deviation coefficient and the steam deviation coefficient are superimposed to obtain the comprehensive deviation coefficient of each screen; in the fourth step, the material selection of the heating surface is adjusted according to the comprehensive deviation coefficient of each screen, and differential design is performed. The screen with large deviation uses good materials, and the screen with small deviation can use slightly worse materials; however, the patent has the following defects:

[0004] The existing system cannot perform real-time diagnosis and abnormal warning on the use of boiler heating surface, and cannot intuitively display the operation status of boiler heating surface, making it difficult for management personnel to quickly and accurately grasp the operation status of boiler heating surface, increasing safety risks and failing to fully guarantee the normal operation of boiler.
