PROBLEM TO BE SOLVED: To provide a refractory material diagnosing system for finding a damaged quantity of a refractory material constituting a furnace chamber of an ash melting furnace. SOLUTION: The refractory material 2 is arranged on a peripheral wall of the furnace chamber 13 in the ash melting furnace 1. A cooling water pipe is arranged for protecting the refractory material 2 from intense heat, and is connected with a branch pipe 14 for separating a plurality of pipes from a cooling water inlet line 3. In the branch pipe 14, a cooling water inlet temperature detector 5 is arranged just before the pipe, and a cooling water outlet temperature detector 7 and a cooling water flow rate detector 6 are arranged in a passage of the branch pipe 14. A temperature detecting device 11 for measuring a furnace chamber inside temperature is arranged in the ash melting furnace 1. Values detected by the cooling water inlet temperature detector 5, the respective cooling water outlet temperature detectors 7, the cooling water flow rate detector 6, and the ash melting furnace temperature detecting device 11 are outputted to a control device 12 to always monitor a wear and tear quantity of the refractory material 2.
