A crystal-growing furnace having a slurry drainage duct structure includes a furnace body, a supporting table, a loading frame, a plurality of eaves elements, and a set of eaves gutters. The supporting table includes a table plate and a plurality of supporting posts. The loading frame includes a lower plate and four side plates, where four elongated eaves boards descend from sides of the lower plate. Four eaves gutters, having V-shaped grooves, are connected with one another and disposed beneath the four eaves elements correspondingly. Therefore, in case high-temperature silicon slurry leaks and drains from a crucible of the crystal-growing furnace, the silicon slurry will first be guided and flows along the elongated eaves boards and down into V-shaped grooves of the eaves gutters so as to prevent the silicon slurry from flowing along periphery of the table plate and down to the supporting posts, such that the supporting posts will not be broken and the crucible not fall down and the silicon slurry not flood. A receiving pan is additionally provided, at a lower body of the furnace body, for containing a great amount of the leaking silicon slurry so as to block the silicon slurry from flowing close to the supporting posts. This will protect the supporting posts from being damaged, and will prevent torsion and deformation incurred to the lower body due to impact of heat by the molten silicon slurry.
