  • Boiler Economizer: Boost Your Boiler's Performance I Explore further

    2021-3-3u2002·u2002That is where boiler economizers come in to reduce that heat loss. Remember, we need a fluid that can use the heat AND is at a lower temperature than the flue gas. Dry Economizer. Feedwater leaving a deaerator at 225 may be 100 F cooler than the boiling temperature in the boiler, so feedwater can absorb the heat.
