What Flame Should Be On Gas Fired Boiler

High CO readings from old Oil Boiler.Should I be worried?

Feb 11, 2013· I had my (1400s sq ft; 2 floor) house reviewed for energy efficiency recently. The guy stuck a probe in the flue of my oil boiler and gas water heater. He showed me Carbon Monoxide levels from the water heater was reading 10ppm and the boiler was 340ppm. He said the boiler was way over the acceptable level (100ppm) and I should call someone for a tune up.

Dec 02, 2010· ideally use a test kit. but with this old boiler there is a cap that you can see flame through, and yes it is possible to see if its ok, it will be a bright yellow flame, with no black wisps of smoke at tips. if you play with the air, its possible to see it go to smoke, and then adjust out of it.

Causes for Flame Failure in a Boiler and Operator Action

Maintaining a good flame in a boiler is the key to a good boiler performance. Unstable flame is always a threat for boiler furnace explosion, which can lead to a large outage of boiler and loss. There are many causes that can contribute to boiler flame failure. Hence it has become a practice of all boiler designers to interlock purging the boiler with boiler start-up. Flame failure in a boiler can be due to many reasons.

Safety controls for any fuel gas fired boiler

For safe operation of any fuel gas fired steam boiler: If too much natural gas flows to a combustor, the burner could go out or the flame could be large enough to cause overheating. If the flame goes out and natural gas continues to flow, a combustible mixture could fill the boiler

Boiler Burners and Types of Burners - Forbes Marshall

Boiler burners are the central element of effective combustion system design which includes fuel preparation, air fuel distribution, furnace design and combustion control. A burner is a mechanical device that supplies required amount of fuel and air and creates a condition of rapid mixing and produce flame.

Boiler Combustion | CleanBoiler.org

Boiler Combustion. CO levels remain constant or are lowered because the flue gas is introduced into the flame in early stages of combustion and the air fuel mixing is intensified. Intensified mixing offsets the decrease in flame temperature and results in CO levels that are lower than achieved without FGR.

Combustion Testing Procedures

Gas and oil fired power burners should be tested up stream from the barometric, as close to the breech area as possible. While stack draft may be an important measurement, fuel oil and gas fired power burners require draft control over the fire to maintain a proper and controlled intake of combustion air.

A number of retrofits are possible for gas-fired furnaces and boilers, but before pursuing any retrofits you should consider the potential added benefits you could receive by simply replacing the furnace. The following retrofits are possible: The most common retrofit is the addition of a vent (or flue) damper.
