Boiler modulation – is more better? - HPAC Magazi

The benefits of boiler modulation are threefold; it reduces cycle losses, it reduces the wear on the components, and it can (but not necessarily as shown later in this article) result in higher thermal efficiencies. But aside from the benefits, what are the impacts of firing rate modulation on gas fired...

Selective non-catalytic reduction involves the injection of a NOx reducing agent, such as ammonia or urea, into the boiler exhaust gases at a temperature of approximately 1400-1600°F. The ammonia or urea breaks down the NOx in the exhaust gases into water and atmospheric nitrogen. Selective non-catalytic reduction reduces NOx up to 70%.
