Selective catalytic reduction (SCR) for NO x removal from utility boilers has been shown to have extremely high removal efficiencies. In recent years, there has been increased focus on a potentially ...

Since this layer is at the same operating temperature as the SCR, this active catalyst layer can “consume” ammonia slip by combining it with any remaining NO X. The well established process was first ...

The enhanced plant performance achieved at the 1,477-MW Morgantown Generating Station shows the value of model predictive control in conjunction with intelligent distributed control algorithms. This ...

•Ammonia Inj.: The total mass flow rate of ammonia injected into the SCR. This is a function of the NOx concentration in the flue gas and the ammonia stoichiometric performance input value. •Steam for ...

Littelfuse, Inc., the global leader in circuit protection, today introduced a series of 40A standard high-temperature silicon-controlled rectifier (SCR) thyristors that are ideal for use as switches ...
