E2Stak for Efficiency & Emission Reductions

The E2Stak is a concept built around Nationwide's proven environmental controls, the CataStak™ SCR System and EconoStak economizers. It combines the CataStak™ SCR systems' low NOx emission reductions with the EconoStak's efficiency savings, in one engineered emissions/efficiency flange to flange package. Through a dual-phased approach, you will reduce your fuel consumption resulting in significant cost savings, while reducing overall emissions.

The first phase of the E2Stak solution, emissions reductions, is achieved with the CataStak™ SCR System, capable of reducing NOx emissions by over 90% to less than 5 ppm for gas-fired boiler applications and 2.5 ppm for gas turbine applications. It is mounted to the exhaust stack of the boiler and the technology uses catalyst and ammonia as a reducing agent to convert NOx to harmless nitrogen and water.

The second phase of the system, energy efficiency, is accomplished using EconoStak economizers. Hot gases from the CataStak™ SCR System flow through the EconoStak and the extended surface finned tube economizer captures valuable waste heat and sends it back into the boiler feedwater or make-up water, saving a considerable amount of fuel and significantly reducing operating costs.

Features of E2Stak Solutions

• Decrease operating costs
• Reduce emissions/pollutants
• Simple start-up and installation
