To calculate the flue gas velocity in an air preheater, you would need to know the volumetric flow rate of the flue gas passing through the preheater and the cross-sectional area of the preheater. You can then use the formula: Velocity = Volumetric flow rate / Cross-sectional area of preheater. This calculation will give you the velocity at which the flue gas is moving through the air preheater.

What is the charge in flue gas particle?
positive
What should be the range of temperature of flue gases at outlet of air pre-heater?
The typical flue gas temp at the inlet to the air heater is about 650-750 DegF range.
If the rocket has an initial mass of 6000 and ejects gas at a relative velocity of magnitude 2000 how much gas must it eject in the first second to have an initial acceleration of 25.0?
To find the mass of gas ejected per second, first calculate the initial force needed for the rocket to accelerate at 25.0 m/s^2. Then, use this force and the relative velocity of the gas to find the mass flow rate using the equation Force = mass flow rate * velocity. This will give you the mass of gas ejected per second.
What is it called when hot smoke gases up and go to the chimmeny?
This process is called "flue gas exhaust," where hot smoke gases from a fire or combustion process are directed up a chimney or flue to be released into the atmosphere.
What happens to the velocity of gas when temperature increase?
When the temperature of a gas increases, the average kinetic energy of the gas particles also increases. This leads to an increase in the velocity of the gas particles as they move faster on average. According to the ideal gas law, an increase in temperature causes an increase in the average speed of gas particles.
How can you calculate flue gas loss on ignecation?
Flue gas loss on ignition can be calculated by measuring the difference in stack gas temperature before and after ignition, along with the flow rate of the gas and its composition. By determining the energy content of the flue gas before and after combustion, the flue gas loss on ignition can be calculated using the energy balance equation. This measurement helps in assessing the efficiency of the combustion process and identifying opportunities for improvement.
What are three instruments that a flue-gas analysis kit might contain?
A flue-gas analysis kit may contain a gas detector for measuring gas concentrations, a temperature probe for measuring flue gas temperature, and a draft gauge for measuring draft pressure in the flue.
What does a flue gas desulphurisation plant do?
A flue gas Desulphurisation (FGD) plant removes Sulphur Dioxide from the flue gas before it is released into the atmosphere and hence reduces our impact on the environment.
What is a vented fireplace?
Usually refers to a gas fireplace, since wood fireplaces are vented by the flue (chimney) Gas fireplaces can be vented (flue) or unvented (no flue)
Can you run gas furnace and gas hot water heater into one flue?
Of course If the flue is sized properly
Why goose neck is used in boilers?
goose neck have following two functions: 1. It increase the speed of flue gas in convective zone of the boiler, as velocity increase heat transfer rate also increases which is necessary for super heaters. 2. It divert the path of flue gas and spread it in all corners of the boiler,...
Where can someone purchase a flue gas analyzer?
A flue gas analyzer is used to check the chemicals in the gasses in one's flue. They can be purchased at most home improvement stores or stores that have a home improvement section.
What is the charge in flue gas particle?
positive
How to calculate the flue gas quantity at air pre heater out let with out any flow measurement devices?
If the flow is 100m3/hrs and line size is 2''
What is the meaning of flue gas?
Flue gas refers to the gases that are emitted as byproducts from combustion processes, such as in power plants, furnaces, and vehicles. These gases typically include carbon dioxide, water vapor, nitrogen oxides, sulfur dioxide, and particulate matter, and can have environmental impacts if not properly treated before release into the atmosphere.
What is the purpose of a bypass on an industrial boiler economiser?
If the boiler fuel contains Sulphur (and most do) combustion products in the flue gas will include Oxides of Sulphur (SO2 and SO3). SO3 combines with water (H2O) to make Sulphuric Acid (H2SO4). If the temperature of the flue gas falls below the dew point, the combination of the acid with the moisture in the flue gas causes corrosion of the flue gas duct work. Bypassing the economiser in the early stages of a boiler start keeps the flue gas temperature above the dew point.
What are three instruments that a flue gas analysis kit might contain?
A flue gas analysis kit may contain a digital manometer to measure draft pressures, a flue gas analyzer to measure levels of oxygen, carbon monoxide, and other gases, and a thermocouple for temperature measurement.
