Acoustic Furnace Gas Thermometer

Babcock-Hitachi K.K. developed an acoustic furnace gas thermometer to realize advanced operational performance by measuring the distribution of gas temperature online and achieving the following. Various combustion properties / heating surface contamination properties : Reduction of harmful components in combustion gases, fouling prevention, control of collected amount of heat in the furnace. Improvement of rate of load change by optimizing overfiring / underfiring. Feature Non-contact type. Less errors due to radiation unlike the thermocouple thermometer High precision even at 1000 °C or more. Good durability, small errors due to radiation. Measurement of spatial average temperature along the acoustic propagation path. Developable to temperature distribution measurement by the CT* technique.
