A NOVEL METHOD TO MEASURE GAS TEMPERATURE WITHIN COMBUSTION CHAMBER

摘要

The invention determines combustion chamber gas temperature in a steam raising system. Quasi-distributed optical sensing array means disposed within the combustion chamber are used for determining the gas temperature. The shift in characteristic reflected spectrum of interrogated light is indicative of the gas temperatures at the individual sensor points Planar profile of combustion chamber gas temperature is deduced from the point temperatures determined using the optical sensing array.
