Abstract

According to the present invention, an air supply pipe connected to an air supply source is connected to a combustion chamber installed in a common heating or steam manufacturing boiler or a thermal generator. A flow control valve is interposed in the air supply pipe. An ejector is interposed in a fuel gas supply pipe where fuel gas is vaporized and transported. A combustible powder supply line is connected to the ejector. Combustible powder is supplied to the fuel gas supply pipe. The vaporized fuel gas and the combustible powder are sprayed to the ignition source in the combustion chamber through a nozzle connected to the lower end of the fuel gas supply pipe in order to create a flame by supplying the combustible powder to the fuel gas supply pipe. Then, a water tank installed in the combustion chamber is heated and the combustible powder is used as a fuel. A rotary valve is interposed in the upper end of the combustible powder supply line and the combustible powder comes in contact with the combustible powder discharge pipe of a hopper, so the fuel gas is prevented from flowing back into the combustible powder supply line. Therefore, the combustible powder is successively supplied to the combustion chamber and is combusted along with the fuel gas. Then the combustible powder becomes a fuel source. The amount of the fuel gas required for the operation of a heating or steam manufacturing boiler or a thermal generator is reduced, so the operation costs of the heating or steam manufacturing boiler or the thermal generator can be reduced. At the same time, environmental destruction, which is caused by a landfill method or a composting method for treatment of combustible waste, such as food waste, carcasses, and manure, can be overcome.
