COMBUSTION WICK

摘要

A combustion wick comprises a fuel conveying portion wherein liquid fuel is soaked up and a fuel gasifying portion provided above said fuel conveying portion wherein of said fuel conveying and fuel gasifying portions, at least the fuel gasifying portion is formed from silica-alumina type ceramic fibers with an organic binder. At least a part of the fuel gasifying portion is impregnated with a coating material composed principally of an inorganic pigment, silicic anhydride and a surface active agent. By impregnating at least part of the fuel gasifying portion with the coating material, no or little tar-like substance is formed or deposited on the fuel gasifying portion.
