Myths and methods for protecting boilers against flue-gas

Stack gas measurements indicate an excess air level of 44.9% with a flue gas minus combustion air temperature of 400°F. From the table, the boiler combustion efficiency is 78.2% (E1). Tuning the boiler reduces the excess air to 9.5% with a flue gas minus combustion air temperature of 300°F. The boiler combustion efficiency increases to 83.1% (E2).

Feb 17, 2016 · Excess air. This is the air that is not required for combustion and is added to the fire to assure safe operation. Think Draft. This is a measurement of the flue gas velocity through the boiler. If the draft is excessive, it could pull the Stack temperature. This temperature is an indication

Improve Your Boiler's Combustion Efficiency

Feb 01, 2010 · Electro-Chemical Analyser. Thermocouple. A flue gas analyser (sometimes spelled flue gas analyzer) is a very useful tool which can be used to measure the efficiency of a boiler. Boiler efficiency can depend on a number of factors, many of which can be tweaked. A flue gas analyzer will also mitigate the impact that you are having on the environment.

Aug 14, 2017 · The only way to avoid sustained flue-gas condensation is to monitor the boiler's inlet water temperature and react to that temperature by limiting the rate at which heat moves from the boiler into the distribution system. This requires the use of a mixing assembly between the boiler and distribution system.
