PURPOSE:To obtain an apparatus capable of generating a particulate (a fine granular substance such as soot) without heating at a high temp., by utilizing a diffused flame. CONSTITUTION:HC fuel such as C3H8 is supplied in a definite amount slightly excessive as compared to the supply amount of air from a fuel supply port 11 and air is supplied in a definite amount from an air supply port 12 while dry air is supplied in a definite amount from a dry air injection port 7. When the fuel is injected from a nozzle 9 to be ignited while air is blown out from an air blow-out port 10, a diffused flame is formed. Because the fuel is supplied in an amount slightly excessive as compared to the supply amount of air, a particulate is generated in a combustion chamber 1. The generated particulate is taken out while diluted with dry air at an outlet 6. Because the diffused flame is uilized, it is sufficient to carry out temp. conditioning to an extent preventing the dewing of moisture unless fuel and air are heated to a temp. of several hundred degree on the order of 1,000 deg.C and handling becomes easy. |
