JudyFlue 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.
