Ducon Environmental Systems
SCR Catalyst for DeNOx Systems Ducon's SNCR DeNOx Systems work by injecting ammonia or urea into the radiant and convection regions of a boiler to treat the flue gases, so the reduction reaction can take place. The reagent comes in contact with the NOx in the flue gas within a specific temperature range. For urea, this range is approximately 1600 F to 2100 F. For ammonia, the range is lower at 1500 F to 1800 F. (read more)Browse Selective Catalytic Reduction (SCR) Systems Datasheets for Ducon Environmental Systems -

Advantages of Process Steam in Manufacturing Process steam heaters generate steam for many manufacturing applications. Sanitizing pharmaceutical equipment, reducing the weight of building materials, and preserving food products all use process steam. Although steam is not the only way to achieve many of these results, it is generally a more cost, time, and energy-efficient method. Steam heaters can create different types of process steam to match the specific needs of a project. Learn a few of the key advantages of process steam...
