Thermal sensing system

A temperature measurement system for a gasifier comprising:

• a first stage gasifier having a first stage refractory wall that defines a first stage gasifier volume;
• a second stage gasifier having a second stage refractory wall that defines a second stage gasifier volume;
• a protruding refractory brick that protrudes from the first stage refractory wall and toward the first stage gasifier volume;
• and
• a temperature sensor having a temperature sensing tip that resides within the protruding refractory brick.
