  • For all types of burners, NOx emissions correlated strongly with the overall amount of excess air in the furnace.Furnace temperature can be used as an indication of NOx generation -- the lower the temperature, the lower the NOx.If bakery or heat-treating operations have furnace temperatures below 800°f, then NOx is probably 50 ppm (0.06 lb/mbtu). Each installation needs to be tested.Recommended to operate with as high an excess O2, and especially with a high plasma index, as possible in order to keep NOx low.........
  • Advanced Technology Flame Plasma Surface Treating System The very properties that make polyolefins so appealing for use in packaging are detrimental to converting processes such as physical vapor deposition printing/decorating, coating and adhesion to other material. In order for polyolefins to be successfully converted, the reactivity of the polymer surface must be increases. This is especially true in the case of physical vapor deposition where, in order to increase adatom nucleation density, substrate surface reactivity must be increased......
  • Effect of Corona and Flame Treatments Effect of Corona and Flame Treatments on Extrusion Coating Performance Properties Various levels of corona and flame treatments were applied to aluminum foil surfaces and then extrusion coated with LDPE. The changes in extrusion coating performance (adhesion, hot tack, and heat seal) as a function of treatment type and level were monitored. Overall, the adhesive strength between the LDPE and aluminum foil interface improved with treatments, flame and corona. Hot tack and heat seal performance were not significantly impacted as a result of surface treating the aluminum foil surfaces...
