Condensing Boilers and Dew Point: 'Tis the Season for

This condensation contributes 1,000 BTU per pound of condensate transferred into the water (at no additional natural gas use or cost!). So, there are two key things we have to look at: The return heating hot water temperature and the dew point of the flue gas. The Roles of Oxygen and Carbon Dioxide in Condensing Boilers. Boilers need oxygen to

Guide to Managing the Condensate for Condensing

The condensing process is achieved by passing the piped hot flue gases through the cooler return water flowing back into the boiler. Flue gas starts to condense when it drops below its dew point of 55°C. This is why condensing boilers are designed to accommodate a return water temperature of 54°C or less.

As a result, heat from flue gases is not transferred to the water side and it is carried away by the flue gases. The best way to tackle the situation is monitoring flue gas temperature just at the boiler outlet and cleaning the tubes when it goes beyond acceptable limits. By treating feed water, the frequency of cleaning can be brought down.

Flue Gas Condensing Temperature - hvac-talk.com

2008-3-13 · As I am now dealing with a job that has Lochinvar CHHN0990 non-condensing boilers that were condensing in the boiler as well as the flue, I've done a little search and found that natural gas flue gas condenses at 60*C, which equals 140*F. Coincidentally, that is the minimum allowable return water temperature to these boilers. Return water less than 140* is no longer a problem.

Flue gas due point question — Heating Help: The Wall

Flue Gas Dew Points I don't think that the "dewpoint" works quite that way. Heated air can hold more pure water vapor than cold air. When the temperature of the air/water vapor drops to a point where the water vapor will condense out, water forms. But it depends on the temperature of the air.
