What is the flue gas flow?
Flue gases are the general name given to the mixed composition gases that are the by-product of a combustion process. A flue is typically a large pipe, duct, stack, chimney or other venting attached to a process system such as a boiler, furnace, steam generator, oven, etc.
What is a flue gas example?
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.
How are flue gases produced?
Flue gas refers to a chemical byproduct substance that is generated as a result of a combustion reaction that has escaped through long pipes such as those in boilers, furnaces or steam generators. Flue gas may also be referred to as exhaust gas and may act as a reactor agent for atmospheric corrosion.
What is the meaning of flue gas stacks?
A flue-gas stack, also known as a smoke stack, chimney stack or simply as a stack, is a type of chimney, a vertical pipe, channel or similar structure through which combustion product gases called flue gases are exhausted to the outside air.
Which is correct way of flue gases flow?
It is generally placed after the economizer; so that the flue gases pass through the economizer and then to the air preheater.
How do you calculate flue gas?
Composition of the dry flue gas from the stoichiometric combustion of 1 kg of biomass: N2 from theoretical air = 4.94 × 0.79 = 3.90 m3. N2 from biomass = 0.001 × 0.224 = 0.0002 m3. CO2 from biomass = 4.33 × 0.224 = 0.97 m3.
What is the difference between fuel gas and flue gas?
Flue gas is the gas exiting 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. Quite often, the flue gas refers to the combustion exhaust gas produced at power plants.
What is the use of flue gas?
At power plants, flue gas is often treated with a series of chemical processes and scrubbers, which remove pollutants. Electrostatic precipitators or fabric filters remove particulate matter and flue-gas desulfurization captures the sulfur dioxide produced by burning fossil fuels, particularly coal.
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 get flue gas?
Flue gas desulfurization units capture the sulfur dioxide (and the sulfur trioxide, if present) and electrostatic precipitators or fabric filters remove particulate matter produced by burning fossil fuels, particularly coal.
