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.
