Abstract
The invention provides a combustion method using a fuel combustion device, a cement manufacturing method, and a cement firing facility provided with the fuel combustion device, and the fuel combustion device is provided with a fuel supply mechanism. The fuel supply mechanism is provided with a combustible powder supply mechanism for supplying combustible powder, a fuel gas supply mechanism for supplying fuel gas, and a non-combustible powder supply mechanism for supplying non-combustible powder. The present invention provides a combustion method using a fuel combustion device, a method for manufacturing cement, and a cement firing facility provided with the fuel combustion device, which can reduce the amount of fossil fuel (as fuel supplied to the fuel combustion device provided in various facilities such as the cement firing facility), and maintain the amount of radiant heat transfer from various burners, thereby reducing the amount of fossil fuel used as fuel supplied to the fuel combustion device provided in the various facilities such as the cement firing facility. As a result, the amount of heat transferred to a heated object such as a powder raw material of cement clinker is maintained so as to maintain a state suitable for firing the heated object, the amount of carbon dioxide discharged from the various devices is reduced, and the various devices can be operated at low cost.
