Abstract:
1. An apparatus for generating PM (particulate matter) in a gas by mixing a liquid and/or gaseous fuel with combustion air and incompletely burning the mixture, comprising: a combustion chamber in which fuels are mixed with combustion air and combusted, a fuel-injection means to inject the fuel to the combustion chamber, and a pilot burner which ignites the air-fuel mixture; the combustion chamber comprising a chassis equipped with an air inlet for supplying combustion air, a gas outlet for discharging the gas in which PM was generated, and a flame entrance leading to the pilot burner, an outer casing incorporated in the chassis, while forming a space between itself and the chassis, and an inner casing incorporated in the outer casing so as to be directly connected to the flame entrance, while forming a space between itself and the outer casing; the outer casing and inner casing being provided with through-holes around the circumference thereof so that the fuel injected by the fuel-injection means into the space between the chassis and the outer casing and the combustion air supplied to the space between the chassis and the outer casing from the air inlet are introduced into the space between the outer casing and the inner casing through the through-holes of the outer casing and mixed there.
