Studies and development of sound pyrometric temperature measuring methods performed on two coal dust furnaces

Temperature parameters derived from acoustic pyrometry produce, in application studies on two different pulverized coal-fired plants, plausible, reproducible time functions and characteristic curves, which can describe the temperature field with its temperature level and temperature distribution and i its performance in interesting combustion chamber cross-sections close to the end of the combustion chamber. Higher, but calibrated reductions in both space and time require feasible technical improvements both in the measuring instrument and the measurement openings. Additional combustion plants will be included in these investigations and will be pursued in different directions with the object, inter alia, of having an immediate influence on the temperature field described by parameters.
