APPARATUS FOR MEASURING FLAME OF COMBUSTOR AND COMBUSTOR CAPABLE OF MEASURING FLAME STATE USING SAME

摘要

The present invention relates to an apparatus and a method for measuring a flame and a combustion state of a combustor. According to the present invention, provided is the apparatus for measuring a flame of a combustor which is configured such that a high voltage or plasma is applied inside a combustion chamber of the combustor such as a combustor of a gas turbine, such that a part of fuel or an oxidant supplied into the combustion chamber is reformed or charged so as to generate charged particles, and a signal modulated due to the mutual interference with the flame is analyzed while these particles reach the probe through an area of the flame to be measured, and therefore, the state of the flame inside the combustion chamber can be accurately measured. In addition, according to the present invention, provided are the combustor which is configured such that, as described above, by using the apparatus for measuring a flame of a combustor provided to accurately measure the state of the flame generated in the combustion chamber, the combustion operation of the combustor is stably controlled based on the measured state of the flame, thereby improving combustion characteristics, and therefore, generation of pollutants such as NOx can be reduced, and a method for controlling combustion of the combustor.;COPYRIGHT KIPO 2017
