IPC: C02F11/06
Filed: 2001-06-11
Abstract: PROBLEM TO BE SOLVED: To provide a hydrous combustible supplying apparatus with which hydrous combustibles are prevented from being recombined with one another and adhering to a hearth, or the like, in a combustion furnace so that efficient combustion can be attained. SOLUTION: The hydrous combustibles moving in a pipeline L5 are divided in the moving direction into hydrous combustible pieces and the surfaces of the hydrous combustible pieces are covered with oil by injecting the oil into the pipeline L5 pulsatively. The oil-covered hydrous combustible pieces are supplied to the combustion furnace 40. As a result, the specific surface area of the hydrous combustibles can be made larger and the hydrous combustible pieces are hardly recombined with one another even when they are brought into contact with one another in the furnace 40. Since the specific surface area of the hydrous combustibles is kept larger, the hydrous combustibles can be heated easily so that efficient combustion can be attained.  The hydrous combustible pieces can be restrained from adhering and accumulating locally on the hearth, or the like, so that the hydrous combustible pieces can be dispersed in the furnace 40 uniformly. Since the calorific value of the hydrous combustibles is increased, incomplete combustion is hardly caused.
