微粉炭だきボイラーの炉内温度計測

抄録

As for the important factors in the measurement of flame temperature in a pulverized coal fired furnace, the characteristics of furnace, components of flue gas, characteristics of flame itself, heat flux conditions of furnace wall, particles in flue gas etcare reviewed based on the actual data.
Then the merits, demerits and present status are explained for various temperature measuring methods from conventional ones such as thermocouple, suction pyrometer, optical pyrometer, colour eye, and radiative pyrometer to the latest ones which are tried in laboratories such as Na-D ray, Raman, CARS, radiation absorption, and holographic methods.
Future technology, such as temperature distribution measuring method by computer tomography is also demonstrated.
