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 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.
What is the difference between flue gas and stack gas?
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.
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 flue gas is measured to determine the efficiency of a gas furnace?
The concentration of carbon dioxide (CO2) in the flue gas is typically measured to determine the efficiency of a gas furnace. By analyzing the presence of this gas, technicians can evaluate how effectively fuel is being burned and whether any adjustments are needed to optimize efficiency.
What is formula for boiler efficiency?
boiler efficiency calculation methods:Input-output methodη = Output / Input Output is defined as the heat that is absorbed by working fluid. Input is defined as the chemical heat of fuel plus the heat that is added to working fluid, air, gas and other fluid circuit in which the fluid circuit across thin layer.Heat Loss MethodHeat loss method is the method that is used to calculate the percentage amount of heat which is not useful. This method is very effective used in an attempt to find potential savings of boiler with heat balance. There are several factors act as the source of heat loss combustion. These factors will be used to calculate boiler efficiency based on heat loss method. The source of heat loss can be seen as following below:a. Heat loss due to dry flue gasHeat loss due to dry flue gas is the heat loss which is contained in dry flue gas such as CO2, O2 and N2. These gases are one of causes of heat loss in combustion process. The high temperature of flue gas coming out from boiler affect amount of heat loss.The weight and heat loss of dry flue gas of combustion of coal can be calculated as following formula:Wdfg = mCO2 + mSO2 + mO2 + mN2Eloss dfg = Wdfg x Cp x (To - Ts)Where:Wdfg = weight of dry flue gas (kg/kg coal)Eloss dfg = heat loss in dry flue gas (kJ/kg)To = temperature of dry flue gas coming out from boilerTs = temperature of surroundingby Gajanan Nalegaonkar
How do you calculate the flue gas velocity in airpreheater?
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 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 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.
