The apparatus consists of an intake valve which feeds into a calibrated water or glycerin jacketed gas burette, this burette is then connected by tubing to two or more absorption pipettes containing chemical solutions that absorb the gases it is being used to measure.
What is meant by 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.
Where are the readings taken on the Orsat gas analyzer?
The volume of the sample is adjusted to 100 mL by bringing the level to the 0 mL graduation. All readings are taken with the reservoir at the same level as the liquid in the burette, ensuring that the sample is at atmospheric pressure.
Which apparatus is used for the analysis of exhaust and flue gas?
The apparatus normally used for the routine analysis of flue gas is the Orsat appparatus. The gases usually estimated are carbon dioxide, oxygen and carbon monoxide.

How the fuel gas is Analysed?
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.
Which are the materials uses in Orsat apparatus?
5.2. 1 A typical Orsat analyzer requires four reagents: a gas-confining solution, CO2 absorbent, O2 absorbent, and CO absorbent. These reagents may contain potassium hydroxide, sodium hydroxide, cuprous chloride, cuprous sulfate, alkaline pyrogallic acid, and/or chromous chloride.
What are infrared gas analyzer used for?
An infrared gas analyzer measures trace gases by determining the absorption of an emitted infrared light source through a certain air sample. Trace gases found in the Earth’s atmosphere become excited under specific wavelengths found in the infrared range.
What is An Orsat gas analyser used for?
An Orsat gas analyser is a piece of laboratory equipment used to analyse a gas sample typically fossil fuel flue gas for its oxygencarbon monoxide and carbon dioxide content. Their stop-cocks are then closed. If playback doesn’t begin shortly, try restarting your device.
What is the Orsat apparatus?
He became aware of the efficiency implications of the fuel/air ratio, excess air resulting in waste of heat in hot exhaust gases, and excess fuel resulting in formation of carbon monoxide, with loss of the fuel’s potential heat. He developed the apparatus now known as the Orsat Apparatus for analysing exhaust gases.
How is chemical absorption reaction done in Orsat apparatus?
Chemical Absorption Reaction in orsat apparatus. FLUE GAS ANALYSIS ORSAT APPARATUS. Since one mole of any gas occupies the same volume under the same conditions of temperature and pressure. The eudiometer reading is taken and the difference of two readings gives the percentage of CO 2 by volume in the gas sample.
Which apparatus gives analysis of dry gas using eudiometer?
The eudiometer reading is taken and the difference of two readings gives the percentage of CO 2 by volume in the gas sample. The same procedure is repeated with the pipettes b and c to find the percentage analysis of O 2 and CO respectively in the flue gas. The remainder is N 2 gas. Thus, Orsat apparatus gives analysis of the dry gas.
