Effects of Infrared Radiant Coating on Porous Media Combustion
Porous media combustion (PMC) shows many advantages over free flame combustion, and it is one of the best way to convert fossil fuel energy to heat. The infrared radiant coating (IRC), which can reduce heat loss and improve thermal efficiency, has been massively investigated during past two decades and applied in industrial heating widely. In principle, the proper coating on porous media can improve infrared radiant emission. Continued from our former researches, as an attempt, we experimentally investigated the effects of IRC on PMC by choosing composite of (50wt%MnO 2 +30wt%Fe 2 O 3 +10wt%CuO+10wt%Co 2 O 3 ) as coating material after reference investigation. Comparative experiments between base-line and IRC PMC are carried out for syngas/air mixture, whose properties and heat value are similar to natural gas, under different firing rate FR=300kW/m 2 ~ 800kW/m 2 and different equivalent ratio ψ=0.6 ~ 0.9. Results indicate that, the IRC PMC shows many distinguished characteristics in combustion process, temperature distribution, pollutants emission and combustion instability. These findings can help promotion of PMC performances
