The present invention relates to a two-dimensional measurement of the concentration and temperature of fine dust precursors, and an active control method thereof. Specifically, the concentration and temperature of NO, which is a fine dust precursor, contained in the exhaust gas of a large combustion system such as a power plant, is 2 It relates to a control method of minimizing the concentration of NO by measuring using the dimensional TDLAS method and spraying ammonia in response thereto. |
