PROBLEM TO BE SOLVED: To efficiently execute melting of a waste by measuring a temperature distribution of a melt bath, deciding a low temperature area lower than a given lower limit temperature and a high temperature area higher than a given upper limit temperature based on the distribution, moving a torch toward the low temperature area, and removing it from the high temperature area. SOLUTION: Meshes are defined on a surface of a molten material of a melt bath 10 with a specified distance from refractories 11 of a furnace wall by a discrimination means 6 receiving a signal from a measuring means 5 or a signal fed through a detecting means 12, and a mesh is cut. Temperatures of coordinate points of the meshes are measured, and a temperature distribution is output. If a temperature of only a range of a certain part such as, for example, a range which easily becomes a high temperature directly under a torch flame exceeds 1,600 deg.C of an upper limit temperature, a signal is transmitted to a torch moving means 3 so that a torch 2 moves to the area of the lowest temperature (low temperature area) in a temperature distribution measuring range. If the overall surface of the molten material is 1,600 deg.C or higher, a signal is transmitted to a torch output control means 4 to reduce an output of the torch 2.
