Abstract
The microwave was irradiated at the combustion field and the influence on the flame height was considered. Stick PMMA was used as a solid fuel. The intensity of microwave was constant. The outer diameter of PMMA was changed. The flame height and the combustion mass were measured. The inverter-controlled magnetron microwave generator was used. PMMA was used as a dielectric substance of the coaxial line. As the results, the flame height and the combustion mass were increased when microwave was irradiated during PMMA combustion. It is effective in combustion promotion to irradiate microwave during PMMA combustion.
