AI Technical Summary

Benefits of technology

This patented technology describes an improved method or apparatus used in flameless dedusters (SDS). These devices have several advantages over existing methods such as reducing NOX emissions during operation without adding chemical agents like calcium chlorite or other reagents. They also include various techniques to enhance cleanliness and efficiency. By utilizing these technologies, they help control harmful geometries within the process vessel, resulting in lesser environmental impact than traditional methods.

Problems solved by technology

The technical problem addressed in this patented text relates to sulfide emissions from fuel burning due to particulate matter (PM) generated during engine operation or other factors such as excessive heating caused by flames produced when fuels like coal have been used for power production. This can cause damage through corrosivity towards materials made with these types of chemicals.
