How Boiler Performance Impacts ESP Neundorfer
This significantly reduces the temperature of flue gas heading downstream to the ESP, from about 700F to about 300F. Flue gas temperature is critical to ESP performance; both ash resistivity and gas volume increase with higher temperatures. The optimal operating temperature for a cold-side ESP is in the 280F-320F range.
