NOx control for high-ash coal-fired power plants in India

For a low-dust environment the typical velocity through the catalyst is in the range of 3.7-5.5 m/s. CFD modelling is also used to determine the distribution of velocity to minimize pressure drop and particulate dropout. Identifying localized high velocities allows prediction of high-wear sites within the SCR unit and the ductwork.
