Boiler Heat Recovery Through Condensate

When Does Condensing Occur In My Boiler? - Smart Boiler

To protect the boiler itself and the flue gas system from this acidic steam, older boilers direct the flue gases outside. Depending on the heating technology, the exhaust gas temperature can be up to 200 degrees Celsius. Condensation of the water vapor in the exhaust gases is thus deliberately prevented. The recovery of the hidden heat

How do you calculate condensate recovery? - AskingLot.com

Feb 12, 2020 · The condensate must be pumped from the vented tank to the collecting tank, and then pumped from the collecting tank to the boiler. Similarly, you may ask, what is condensate recovery? Condensate recovery is a process to reuse the water and sensible heat contained in the discharged condensate.

Condensate Recovery

Since temperature is a driving force in oxygen corrosion even small quantities of dissolved oxygen in condensate can cause severe corrosion. Oxygen removal in the condensate system is determined by the source. If oxygen is flashing with the steam from the boiler, use or repair of a de-aerating heater could help eliminate this.
