(3) Ceramic Filters

Ceramic filters boasts reliability and high efficiency and can trap dust at temperatures above 250°C, which has been regarded as the critical temperature for conventional fabric filters. Because it functions at high temperatures, there is no need for a flame prevention system, spark prevention device, cooler, or spraytower.  Ceramic filter also leads to energy and water savings.

 Ceramic filters can be used even at a temperature of 900°C and shows high

filtration efficiency against fine particles. In addition, it has resistance to sparks, incandescent particles, and accidental flame. The Ceramic filters are resistant to acid and alkaline corrosion and do not require a lot of space as air dilution is not necessary.
