PROBLEM TO BE SOLVED: To obtain a fusion furnace which is stably used for a long time by making a slag guiding means of a passage for flowing molten slag in the fusion furnace into a discharge chamber of a high temperature and corrosion resistant material into a shape with excellent flowing characteristic and difficulties of cracks, and prevents the slag guiding means from opening. SOLUTION: This fusion furnace generates molten slag by burning incinerated ashes introduced to a swing fusion chamber 2 via an air introduction pipe 5, and drops and stags the molten slag to a molten pool chamber 3. The molten slag is made to flow to a discharge chamber 11 by a slag guiding means, namely a flume 12 from the side of a shielding wall 13, dropped in a slag pit 16, and recovered. The flume 12 is formed with a V-shaped groove by combination of chromium alloy blocks. The flume 12 is attached to a refractory, preventing the blocks from opening with a grooved bar-like block.
