At the scene of the Blue Sky Defense Battle, there is a little-known ‘key gentleman’ silently guarding our respiratory health – it is neither a huge absorption tower nor a complex control system, but a flue gas desulfurization nozzle(FGD spray nozzle) with a diameter of only a few tens of millimeters – this inconspicuous small component is the core of the efficiency of the entire desulfurization system.
As the “throat” of the desulfurization system, the nozzle needs to withstand the “triple test” of high temperature, strong corrosion, and high wear. Traditional metal materials often experience problems such as pore size expansion and atomization failure after several months of erosion by acidic slurries; Although engineering plastics are corrosion-resistant, they are difficult to withstand sustained high temperatures. At this time, a breakthrough achievement from modern materials science – reaction sintered silicon carbide ceramics, is rewriting industry standards.
This new type of ceramic, known as the “industrial black gold,” exhibits astonishing characteristics at the microscopic level: millions of silicon carbide crystals form a dense network through special sintering processes, creating a hardness comparable to diamond. When the desulfurization slurry containing gypsum particles is flushed at high pressure and speed, its wear rate is much lower than that of ordinary steel. More importantly, it has a natural “superpower” to resist acid and alkali corrosion, and can maintain its indestructible body even under conditions of severe pH fluctuations.
In terms of stability, this material exhibits remarkable service life. The atomization angle deviation of this material nozzle is still controlled within a very small range after several years, and this precision retention ability extends the equipment maintenance cycle several times.
For customers who need to use desulfurization systems, choosing silicon carbide nozzles is like purchasing “lifetime insurance” for the equipment. It not only reduces the cost of spare parts replacement, but more importantly, ensures the continuous stability of desulfurization efficiency – which is directly related to the environmental protection standards and sustainable production of enterprises.
The nozzle components manufactured using patented precision machining technology undergo multiple rigorous tests, including atomization testing, before leaving the factory to ensure that the inherent advantages of the material are transformed into tangible environmental benefits.
On the new journey led by the “dual carbon” goal, technological innovation is injecting lasting vitality into environmental protection equipment. The widespread application of reaction sintered silicon carbide ceramic nozzles is a vivid footnote to the material revolution empowering green manufacturing. When we look up at the clear blue sky, we may also think of these “ceramic guardians” who have hidden their skills and fame – they are guarding the purity of thousands of meters with millimeter level perseverance.
