Flue Gas Recirculation: History and Uses - EnviroPower

In order to reduce NOx, recirculated flue gas must be mixed with air before entering the burner or cylinder. This is somewhat different than the temperature control setup, where flue gas in blown directly into the boiler. Thus, while FGR is effective for both boiler temperature control and NOx reduction, they require different injection points.

Experimental investigation on flue gas emissions of a

Flue gas emission concentrations were measured by gas analysers. If the flow rate of the flue gas is known, quantitative analyses of the emissions could be done easily. When the biomass boiler is in operation at its design load with a flue gas O 2 concentration of 6%, the dry flue gas flow rate was estimated to be ∼550 l (at 15°C and 1 atm)/min.

Valmet Acoustic Pyrometer for flue gas temperature

Acoustic Signal Receivers detect sounds in the boiler via a tube through the wall and are housed in pressure-sealed NEMA 4 enclosures. Boiler tube bends are not required to mount the Acoustic Signal Receivers. Key applications for the Valmet Acoustic Pyrometer include furnace flue gas temperature and temperature distribution measurement. Benefits

Flue Gas Condensers | CleanBoiler.org

An SRU flue gas waste heat recovery system can be installed with any natural gas or LPG fired power burner boiler or heating unit. When the heating unit is required to operate on oil the flue gases will have to be bypassed from the waste heat recovery unit. Flue gas recovery systems have been used around the world for over 20 years.

Improve Your Boiler's Combustion Efficiency

2013-5-2 · A boiler operates for 8,000 hours per year and annually consumes 500,000 million Btu (MMBtu) of natural gas while producing 45,000 lb/hour of 150-psig steam. 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).

What is a High Efficiency Gas Boiler? | U.S. Boiler

The biggest difference between high efficiency boilers and conventional boilers is something called "stack temperature," essentially the temperature of the flue gas as it leaves the boiler. The water vapor that is trapped in the flue gas will condense into water when it reaches a certain temperature (commonly known as the "dew point").
