Where extreme temperatures prevail, their measurement by conventional methods becomes difficult. In this aggressive atmosphere, many methods suffer from problems like drift, wear and measurement errors due to thermal radiation.
The acoustic gas temperature measurement uses a characteristic of the gas itself, as the speed of sound in the gas depends on its temperature. Thus, our system can measure the gas temperature regardless of the radiation, for example, from the background of the furnace. We use combustion control & active balancing control and for denitrification.
