	Flue gas - Wikipedia, the free encyclopedia
		Flue gas is gas that exits to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator.
		At power plants, flue gas is often treated using filters and scrubbers, which remove certain pollutants.
		Electrostatic precipitators remove particulate matter and flue gas desulfurization captures the sulfur dioxide produced by burning fossil fuels, particularly coal.

	Flue gas desulfurization - Wikipedia, the free encyclopedia
		Before flue gas desulfurization was installed, the emissions from this power plant in New Mexico contained excessive amounts of sulfur dioxide.
		Flue gas desulfurization (FGD) is the current state-of-the art technology used for removing sulfur dioxide (SO) from the exhaust flue gases in power plants that burn coal or oil to generate the steam for the steam turbines that drive their electricity generators.
		Flue gas desulfurization scrubbers have been applied to combustion units firing coal and oil that range in size from 5 MW to 1500 MW.

	Example of a portable gas analyser that is configurable from two sensors to nine sensors
		A 4 gas analyser or 5 gas analyser would generally be intended for EPA compliance testing and jobs of that nature and the more complicated flue gas analysers will be used for laboratory jobs or research into pollution control devices.
		Such a portable flue gas analyser is easy to transport, falling into the category of hand baggage for air travel and being light in weight.
		The flue gas analyser is no longer so expensive that only huge companies can afford to buy and operate a combustion gas tester.When you add in the possibility of extra profit by so-called CO trading as envisaged in the Kyoto Protocol, the reasons sum up in favour of testing.

	Flue Gas Desulfurization
		Flue gas desulfurization is a chemical process to remove sulfur oxides from the flue gas at coal-burning power plants.
		IGCC uses a combined cycle format with a gas turbine driven by the combusted syngas from the gasifier, while the exhaust gases are heat exchanged with water/steam to generate superheated steam to drive a steam turbine.
		This fuel gas is combusted in a topping combustor and adds to the combustor's flue gas energy entering the gas turbine, which is the more efficient portion of the combined cycle.

	World Bank - Wet Flue Gas Desulfurization (FGD)
		In wet scrubbers, the flue gas enters a large vessel (spray tower or absorber), where it is sprayed with water slurry (approximately 10 percent lime or limestone).
		In some installations, the flue gas is reheated to avoid corrosion downstream in the power plant.
		The calcium in the slurry and the SO in the flue gas form calcium sulfite or calcium sulfate, which are removed by dewatering and settling into a thickener (center).

	Flue Gas Conditioner
		Used in conjunction with the ECA 450, the Flue-Gas Sample Conditioning System functions to remove water vapor from the flue-gas sample, thus preventing the formation of water droplets inside the probe hose.
		If water droplets were to form, a portion of the gas sample could be absorbed by the water, thus resulting in lower-than-actual NO and SO readings.
		Water vapor is removed by passing the gas sample through a Peltier Cooler where the sample is chilled, causing the water vapor to condense.

		The absorber washes the sulphur dioxide from the flue gas.

		This regenerative air heater extracts the heat of the flue gas before reaching the absorber and emits the heat after the gas leaves the absorber.

	Keppel Seghers - Flue Gas Cleaning
		This homogeneous mixture of reagents and flue gases is maintained throughout their passage through the reactor, which ensures a pre-determined reagent/gas contact time is achieved providing very high scrubbing effiencies.
		This type of flue gas cleaning, in which the pollutants are not only captured, but actually destroyed, is currently considered the best available technology (BAT).
		Before entering the Keppel Seghers DEDINOX the flue gas has to be heated to a working temperature, somewhere between 150 and 300°C. At the entrance of the reactor a NH3-solution is injected in order to create reducing conditions for nitrogen oxides and achieve a good reaction velocity.

	Use of flue gas analyser for stack monitoring
		Flue gas analysis and a flue gas analyser enable you to measure the concentrations of the pollutants present and to adjust your burners for optimal combustion.
		Known under many names, flue gas analysis, stack emissions monitoring or simply gas analysis.
		Without a flue gas analyser, there is no real way of checking your own level of compliance and hence avoiding nasty surprises when official testing with a flue gas analyser is carried out.
