Which method is used to analyze the flue gas?
Orsat appparatus
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.
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. Once this has been established, the sample entry stopcock is closed.
Which Orsat apparatus gives more precise results in the analysis of flue gas?
Short orsat apparatus gives more precise results than long orsat in the analysis of flue gas. Explanation: Long orsat or precision model orsat is used for analysis of quite complicated mixtures and which gives very accurate results in competent hands.
What is orsat method?
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.
Do Orsat apparatus gives?
Orsat apparatus: An Orsat gas analyzer uses a chemical absorption technique to determine mole fractions of CO2, CO, and O2 in the exhaust gas. Since it cannot measure H2O content, the exhaust gas sample is cooled to atmospheric temperature, so most of the water vapour in the combustion products gets condensed out.
Which solution is mainly used in Orsat apparatus?
The most common absorbents are: Potassium Hydroxide (Caustic Potash) for carbon dioxide.
What is the working of Orsat apparatus?
The Orsat Apparatus is used to Analysis the products combustion, this is done by the process explained below. It consists of burette to measure and there are three flasks. There is a chemical in the flasks to absorb different types of gasses, like CO 2, O 2, CO.
How does a combustion analyzer work?
Combustion analyzers are multifunction instruments designed to calculate the efficiency of all types of boilers, heaters and furnaces by measuring a range of parameters such as stack temperature, flue pressure and levels of gases. Combustion occurs when fuel, generally a fossil fuel, reacts with oxygen to produce heat.
