To test the oxygen level, a tool called a combustion analyzer is used to measures the amount of oxygen remaining in the flue exhaust gas. While there are many combustion analyzers on the market, all of them include an oxygen sensor.
What is the function of flue gases?
9.4 Flue gas
Combustion is used primarily for heat by changing the potential chemical energy of the fuel to thermal energy . This occurs in a fossil fuel-fired power plant, a home furnace, or an automobile engine. Combustion is also used as a means of destruction for our unwanted materials.
Why do we measure flue gases?
Flue gas analysis will give you an indication of whether or not you are achieving maximum possible carbon combustion in your fuel . You can also analyse your flue gas in order to determine environmental impact and whether you are maintaining compliance with local emissions regulations.
Why is orsat analysis important?
An Orsat gas analyser is a piece of laboratory equipment used to analyse a gas sample (typically fossil fuel flue gas) for its oxygen, carbon monoxide and carbon dioxide content. Although largely replaced by instrumental techniques, the Orsat remains a reliable method of measurement and is relatively simple to use.
Is flue gas analysis?
A flue gas analyzer will enable you to measure the concentrations of various gases and adjust burners on a boiler to help achieve optimal combustion . Efficient combustion also reduces emission of pollutants such as nitric oxide (NO), nitrogen dioxide (NO2), sulfur dioxide (SO2), and particulate matter.
How do you control flue gas?
Flue gas treatment technologies are post-combustion processes to convert NO x to molecular nitrogen or nitrates. The two primary strategies that have been developed for post-combustion control and are commercially available are selective catalytic reduction (SCR) and selective non-catalytic reduction (SNCR) .
What gases are in flue gas?
What is in the flue gas? Flue gases are a mixture of combustion products and include water vapour, carbon dioxide, particulates, heavy metals and acidic gases .
What is a Fyrite?
Testing Kit for Oxygen or Carbon Dioxide Measurement . The Bacharach Fyrite ® gas analyzer is ideal for contamination tests in rooms, mines, pressurized chambers and other confined spaces.
What should flue gas Analyser readings be?
You could have a good efficiency with acceptable CO2 levels and spewing carbon monoxide up the flue. Many burner manufacturers look for a reading of between 8 1/2% to 10% in the flue gas.
What is the ideal CO2 content of flue gas?
Carbon dioxide – CO 2 – is a combustion product and the content of CO 2 in a flue gas is an important indication of the combustion efficiency. Optimal content of carbon dioxide CO 2 after combustion is approximately 10% for natural gas and approximately 13% for lighter oils .
What is orsat analysis?
A measurement of the oxygen, carbon dioxide, and carbon monoxide in a mixture of gases , usually from the exhaust of combustion processes such as boilers, furnaces, fired heaters, and combustion engines. ... Orsat in 1873, it involves absorption of the gases onto materials contained in pipette tubes.
How does a flue gas Analyser work?
A Flue gas analyser measures flue gases – You place its’ probe in the chimney or appliance exhaust and see what levels of Oxygen (O2), Carbon Monoxide (CO), Carbon Dioxide (CO2) and flue gas temperatures are present . ... They should also offer the option to either print or store the measurements for later review.
What gases are in Coke?
Coke gas is a by-product of industrial coke production from pit coal, coke gas is created by high-temperature dry distillation of coking coals in the absence of oxygen. The gas mainly consists of hydrogen (50-60%), methane (15-50%) and a small percentage of carbon monoxide, carbon and nitrogen .
What is syngas formula?
This can vary significantly depending on the feedstock and the gasification process involved; however typically syngas is 30 to 60% carbon monoxide (CO) , 25 to 30% hydrogen (H 2 ), 0 to 5% methane (CH 4 ), 5 to 15% carbon dioxide (CO 2 ), plus a lesser or greater amount of water vapor, smaller amounts of the sulfur compounds ...
What is fuel gas made of?
Gasoline is a fuel made from crude oil and other petroleum liquids . Gasoline is mainly used as an engine fuel in vehicles. Petroleum refineries and blending facilities produce motor gasoline for sale at retail gasoline fueling stations.
What is combustion flue gas analysis?
Combustion analysis begins with the measurement of flue gas concentrations and gas temperature , and may include the measurement of draft pressure and soot level. To measure gas concentration, a probe is inserted into the exhaust flue and a gas sample drawn out.
