Application of grille anti-friction technology on supercritical boilers

      With the rapid development of China's economy, the demand for electricity is getting bigger and bigger. Power development is also growing rapidly, and the energy and environmental protection situation is becoming increasingly serious. In order to better meet the rapid development of China's economy with electricity, China's thermal power generation units are developing to supercritical, ultra-supercritical.

　　Whether supercritical, or ultra-supercritical boilers will have wear and tear problems, wear and tear problems are not solved for a long time will also form a leaky tube and burst tube shutdown accidents.

　　Analysis of supercritical, ultra-supercritical boilers burst causes, we found that supercritical, ultra-supercritical boilers are mainly due to uneven heating of the heating surface, resulting in water-cooled wall heat leading to pulling cracking burst.

　　After years of research and discovery, we introduced the grill anti-friction technology in 2014. Previously this technology has been applied to general circulating fluidized bed boilers with good anti-friction effect. From there, it was applied to supercritical and ultra-supercritical boilers, and the same good results have been achieved.

　　Our grid anti-wear technology is an active anti-wear technology, which is more stable and durable than the traditional spray anti-wear, and can solve the wear problem of circulating fluidized bed boilers more effectively.
