PURPOSE: To obtain stable combustion for a wick, by determining a specific value as the rate of surface-active agent occupied in a coating material, as well as to impregnate a fuel vaporizing part, made of ceramic fiber, with the coating material, made of inorganic pigment, silica, and surface-active agent.
CONSTITUTION: A main wick is made of ceramic fiber of silica-alumina system, added with polyacrylic ester. A fuel vaporizing part 3 is impregnated with coating material, made of inorganic pigment, silica, and surface-active agent, and the rate of surface-active agent occupied in the coating material is 0.2W5%. With such an arrangement, generation and accumulation of tar material are inhibited, so that stable combustion can be obtained for a wick for a long time.
