Stationary gas turbines were originally developed as air craft engines and are applied to drive generators. Installations are used to generate peak load electrical power and often together with a waste heat boiler to generate heat energy. The flue gas composition is very similar to that of gas fired furnaces.
Measure flue gas composition and temperatures at selected firing positions recommended O2% and CO2% Fuel O2% CO2% Natural gas 1.5 10 No. 2 fuel oil 2.0 11.5 No. 6 fuel oil 2.5 12.5 Note: percentages may vary due to fuel composition variations
Apr 01 2010 · According to an FGD manufacturer the optimal flue gas temperature for a desulfurization process is approximately 149F (65C). Cooling of the flue gas to
Optimizing air intake for boiler operation requires continuous measurement of the oxygen concentration in the flue gas. The typical package boiler is a water tube boiler or flue and smoke tube boiler with a capacity of 5 to 20 t/h (average steam generation capacity). The most widely used fuels are heavy oil light oil kerosene and gas.
Acoustic Signal Receivers detect sounds in the boiler via a tube through the wall and are housed in pressure-sealed NEMA 4 enclosures. Boiler tube bends are not required to mount the Acoustic Signal Receivers. Key applications for the Valmet Acoustic Pyrometer include furnace
Feb 01 2010 · A flue gas analyser (sometimes spelled flue gas analyzer) is a very useful tool which can be used to measure the efficiency of a boiler.Boiler efficiency can depend on a number of factors many of which can be tweaked. A flue gas analyzer will also mitigate the impact that you are having on
Using a Flue Gas Analyser. Flue Gas Analyers should be used for the following two purposes: Appliance testing 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.
Jan 01 2016 · Using this technique the true nature of the flow profile can be determined and a reliable air flow measurement (typically accurate to about 2 percent with good repeatability) can be obtained where it is needed on the boiler. Oxygen measurement.
A 20ºC (36ºF) reduction in flue gas temperature will improve boiler efficiency by about one percent. Even with well-adjusted burners providing the minimum flue gas temperatures while achieving complete fuel combustion the exit temperatures of the flue gas may normally range from 175ºC (350ºF) to
Valmet Acoustic Pyrometer is a non-contact measurement device that obtains highly accurate instantaneous flue gas temperature data in any area of the boiler.
