Flue Gas Analysis | CleanBoiler.org

Flue Gas Analysis is performed by inserting a probe into the flue of the furnace, boiler, etc., between the last heat exchanger and draft diverter or any source of make-up air that could enter the flue that did not pass through the combustion process. This is known as 'in-situ' testing.

Flue Gas Condensing Temperature - HVAC-Talk:

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 60C, which equals 140F. Coincidentally, that is the minimum allowable return water temperature to these boilers. Return water less than 140 is no longer a problem.

Gas Condensing Boiler - Condensing Gas Boilers

Condensing boilers – Chimney / Flueing System. With the installation of condensing gas boiler, another benefit is that the flue system can often be a plastic pipe system, which means that they are smaller in diameter than conventional gas boilers, cheaper, easier to install, lighter in weight and easier to fit.

Theoretical prediction of sulfuric acid condensation

Prediction of acid condensation has a critical role in designing heat exchangers to recover water vapor from power plant flue gas. Rates of mass transfer for condensation of sulfuric acid vapors onto heat exchanger tubes were theoretically investigated and a computer program for numerical simulations of sulfuric acid (H 2 SO 4) condensation in a flue gas condensing heat exchanger was developed.

Standard gas and condensing gas boilers - Champion

Standard gas and condensing gas boilers: Gas Boiler Uses. In order to condense the flue gases and consequently be able to extract from them the latent heat of condensation water must return to a condensing boiler from the heating system at below 53C. Hydronic Underfloor Heating can achieve this because it uses low flow temperatures.

Flue Gas Condensation - Babcock amp; Wilcox

Flue gas condensation increases energy recovery by 20-25%. The condensation of flue gas in both heat exchangers and absorption heating pumps is affording huge gains in energy recovery. The system condenses the flue gas in the washing tower by cooling the gas, extracting the heat, and sending it to the district heating grid.
