Abstract
The present relates to a portable catalytic drying apparatus for use in applications such as drying, curing, polymerisation and cross-linking of organic coatings and compounds. The apparatus comprises a catalytic combustion chamber where a co-current lean mixture of fuel and air is combusted, a casing connecting a fuel supply to the combustion chamber, a regulating valve for controlling the flow of fuel, and an injector for mixing the fuel with air thereby providing a lean mixture of uniform fuel-air concentration.
Claims5
1- A portable catalytic drying apparatus comprising:
- a portable casing for connecting to a fuel supply and for receiving fuel therefrom;
- a regulating valve for controlling the flow of fuel from the fuel supply;
- an injector for mixing the flow of fuel with air thereby providing a co-current lean fuel-air mixture;
- a combustion chamber comprising a protection grille, a perforated diffuser plate, a ceramic insulation blanket and a porous pad impregnated with catalytic material where the co-current lean mixture of fuel and air is combusted;
- whereby after ignition of the fuel-air mixture in the combustion chamber, the portable catalytic drying apparatus generates heat.
2- The apparatus of claim 1, comprising moveable handles and adjustable straps enabling easy carrying and positioning.
3- The apparatus of claim 2, wherein the portable catalytic drying apparatus is lightweight enough to be manually handled, used and operated by a single person, and completely autonomous.
4- The apparatus of claim 1, wherein the apparatus can be attached to a base equipped with piezoelectric means for igniting the fuel-air mixture before the apparatus is used;
5- The apparatus of claim 1, wherein a co-current mixture of fuel and air typically with 45% excess air is combusted.
