Abstract :
One of the most popular methods for the flue gas denitrification (DeNOx) in the coal-fired power plants is the selective catalytic reduction (SCR). The denitrification efficiency depends highly on the uniform distributions of the ammonia concentration and the velocity at the entrance of the catalyst layer. In this work, three-dimensional CFD simulations are carried out for a flue gas DeNOx facility of a 300 MW coal-fired power plant. Specially, the influence of the gate leaf on the distribution of the velocity is investigated. The radius, arc length as well as the installation positions of the gate leaf are determined.
