Q & A > Question Details
We have two TIC in reformer heater outlet manifolds for temperature control which act on fuel gas of heater. Low limit of these TIC,s are 700°C, but in some cases (i.e start up) we need to control temp. lower than 700°C. One of our operators suggested we change the lower limit of TICs to less than 700°C. Is this possible without any safety and design problems?

To increase the total range of control for the TIC should not be a problem. But you should think about the accuracy of the instrument, which will definitely go down by increasing the span.
