Flue gas is the gas that is emitted from a combustion process within a building or industrial facility, while stack gas refers to the mixture of gases emitted from a chimney or stack. In general, flue gas is the specific type of gas that is produced from a specific process, while stack gas is the broader term that encompasses all gases emitted from a stack or chimney.

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 should be the rang of temperature of flue gas at outlet of air preheated?
The ideal range of temperature for flue gas at the outlet of an air preheater is typically between 250°C to 350°C. This range allows for efficient heat recovery from the flue gas while ensuring that the temperature is not too high to cause damage to the preheater or downstream equipment.
What is in situ flue gas analyzers?
In-situ flue gas analyzers are devices that measure the components of exhaust gases directly within a combustion system, without the need for sample extraction. They are used to monitor emissions and optimize combustion efficiency in industrial processes such as power plants, refineries, and incinerators. This type of analyzer provides real-time data for immediate feedback and control.
Why doesn't smoke fill the entire house when a fireplace is lit?
Smoke from a lit fireplace is carried up the chimney due to the natural draft created by the temperature difference between the inside and outside air. The chimney's design and height help to facilitate the flow of smoke out of the house, preventing it from filling the entire space. Proper ventilation also plays a role in preventing smoke from lingering inside the house.

What is an application of flue gas?
About the most common application of flue gas is as a heat source. Recall that flue gas is the stack gas from plants fired with combustibles (coal, oil, gas, biomass, etc.), and it exhausts into the atmosphere. We spend a lot of money monitoring stack gas to keep the combustion process as tightly controlled as possible. That minimized emissions. The heat in the stack gas can be used to heat water or the like, and the preheated water can then be fed back into the boilers to create the steam that drives the turbines that generate electric power (which is one example, but a common one). The heating of the (boiler) feedwater with the flue gas increases the efficiency of the whole operation. It's classic steam cycle power generation, and the preheating of feedwater within the stack (by the flue gas) is a time-proven tactic to reduce costs.

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

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 do scrubbers work?
particulate scrubbers typically run the flue gas between metal plates charged with static electricitygas scrubbers bubble the flue gas through large water tankssulfur scrubbers use catalysts and water to make sulphuric acidetc.
