High Energy Density for Drying of Coated Webs – Porous Burner Combustion a New Approach

Existing gas fired burners work in the medium wave IR range at 1000℃ and an energy density of 200 ㎾/㎡. The patented porous burner technology reaches the short wave IR spectrum (1450℃) and comes up to an energy density of 1000 ㎾/㎡. This technology is of great interest for various applications in paper industry. Speeding up existing coating lines can be realized without a major revamp of the line. Main characteristics of this new developed technology enable a better process control. In this paper the porous burner technology for paper industry is evaluated.
