  • Economizer By-pass - Boiler and Pressure Vessel ...

    2008-3-17 · The boiler is critical to the operation (no production when it is down!). We are considering by-passing the feedwater around the economizer (feedwater directly to the boiler steam drum). Because of the downstream scrubber system, the boiler exit gases (700-800F) must be cooled to <400F.
