NOVELTY - The apparatus (1) has extraction tank (6) which is provided to extract soluble coal component from slurry formed by mixing coal and solvent heated with preheater (4) to solvent. A lock-hopper (5) is connected to supply pipe (10) in downstream than the preheater. A gravity settling tank (7) is provided to separate the solution portion containing the coal component from slurry. The solvent splitter (8,9) is provided to perform the evaporation separation of the solvent from solution portion separated with the gravity settling tank so as to obtain ashless coal.    USE - Apparatus for manufacturing ashless coal such as hyper-coal (HPC), bituminous coal, subbituminous coal, and wood coal.    ADVANTAGE - The ash content is removed from the coal, so that the ashless coal is obtained efficiently. The mass production of ashless coal is increased. The extracting efficiency of the ashless coal is improved. The time required for extracting the ashless coal is reduced. The cost of the manufacturing apparatus is reduced.    DETAILED DESCRIPTION - The manufacturing apparatus has supply pipe which is arranged in upstream than the lock-hopper, and which is equipped with pump (3) that conveys solvent to the extraction tank in turbulent flow state. The temperature of the solvent heated with the preheater is 300-450 degrees C. The preheater is configured to heat solvent more than the temperature of the slurry in the extraction tank. An INDEPENDENT CLAIM is included for the method for manufacturing the ashless coal involves the heating a solvent by heating process. The coal mixing process is performed to mix the coal and solvent which are supplied by pressurizing the supply portion (17) to the supply pipe. The coal is supplied to the supply pipe in the solvent is heated at heating process, so that the solvent is not flowed backward, and supllied into slurry. The extraction process is performed to extract the soluble coal component from slurry obtained by coal mixing process to solvent. The separation process is performed to separate the solution portion containing the coal component from slurry from which the coal component is extracted at extraction process. The ashless-coal acquisition process is performed to evaporation separation of solvent from solution portion separated by separation process to obtain ashless coal. The conveyance process is performed to convey solvent to coal mixing process in turbulent flow state. The coal mixing process is performed in the turbulent flow state. The solvent is heated more than the temperature of the slurry in the extraction process.
