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.

Experimental investigation on flue gas emissions of a

Feb 23, 2010 · 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.

Flue Gas Analysis Table | CleanBoiler.org

Flue Gas Analysis Table Introduction. See Flue Gas Analysis. Operation. Using a Flue Gas Analyzer or any meter designed to measure oxygen or carbon-monoxide, and taking the flue gas temperature and the temperature of the combustion air, the following Table can be used to determine combustion efficiency when operating on natural gas.

Combustion Analysis Basics - Home | TSI

When determining heat loss from the flue, the temperature of the supply air is subtracted from the flue gas temperature. This gives the net temperature and accounts for the heat supplied to the system by the supply air. Some heat loss is unavoidable. The temperature in the flue needs to remain high enough to avoid con-densation inside the stack.

⇔ Airflow and flue gas flow is slightly lower or about the same. Natural gas boilers operate at lower excess air (O2) and a different airflow requirement for stoichiometric combustion. Coal fired boilers normally operate with 3-3.5% O2 (about 20% excess air). Whereas natural gas boilers normally operate at 1-1.5% O2 (about 7% excess air).

Symptoms: Aggressive localized boiler tube corrosion and loss of tube wall.Pits can act as stress-concentration sites which can be initiation points for stress-related corrosion mechanisms. Causes: Oxygen pitting occurs with the presence of excessive oxygen in boiler water.It can occur during operation as a result of in-leakage of air at pumps, or failure in operation of preboiler water

Calculator: Flue Gas Analysis | Thermodyne Boilers

Flue Gas Analysis Calculations. Flue gases are formed on combustion of air with fuel in the presence of heat. Combustion of fuel release flue gases which is a mixture of Carbon Dioxide, Carbon Monoxide, Sulfur Dioxide, H 2 O Vapor, Nitrogen or Nitro-Oxides, Oxygen and ash particles. The quantity of flue gases is also calculated using stoichiometry calculation when air reacts with the fuel.

Flue gas - Wikipedia

The flue gas enters the lower part of the desulfurization absorption column under the action of the booster fan after being dusted by the dust collector. In the rising process, it comes into full contact with the falling limestone slurry sprayed by the spray. SO 2 in the flue gas is absorbed by the slurry and falls into the slurry pool at the bottom of the column.

Draft - Draft is the negative pressure (vacuum) of the flue gas measured at any point in the boiler, expressed in millimeters of water column (kilopascals). Economizer - A series of tubes located in the path of the flue gases. Feedwater is pumped through these tubes on its way to the boiler in order to absorb waste heat from the flue gas.
