Temperature monitoring system in GSP (Generalized System of Preference) gasification furnace

The utility model provides a temperature monitoring system in a GSP (Generalized System of Preference) gasification furnace. The temperature monitoring system is used for solving the problem of incapability of obtaining the adhering slag situation of a water wall due to the incapability of monitoring the temperature in a water wall gasification furnace and the problem of lack of references for adjusting an oxygen-to-coal ratio and a steam-to-coal ratio, adjusting the temperature in the gasification furnace and the like in the prior art. The temperature monitoring system comprises a thermometer, wherein a tested point at a test end of the thermometer enters the gasification furnace through a hand hole on the shell of the gasification furnace; the tested point at the test end is located on the side surface of the water wall; the other end of the thermometer is supported outside the GSP gasification furnace by the hand hole and is used for sending the monitored temperature in the water wall gasification furnace
