What is in situ flue gas analyzers?
in situ refers that has not been moved from its original place of deposition. this type of flue gas analyzer fixed in stack.
Flue gas analysis by Orsat apparatus?
An Orsat gas analyzer is a piece of equipment used in labs to analyze gas samples including flue gas. The Orsat analyzes the oxygen, carbon dioxide, and carbon monoxide content of the gas.
Why doesn't smoke fill the entire house when a fireplace is lit?
The hot air from the fire is less dense than the rest of the air in the house, and is pushed upward into the flue. As the flue fills with hot less-dense gas the pressure difference expelling it increases, and it draws additional hot gasses (smoke) into the flue as the column of gas in the flue rises. When the hot gas exits the flue, its still less dense than the air around it and continues to rise away from the house.
What is the difference between flue gas and stack gas?
There is no difference. They both refer to the product that leaves a furnace post combustion
How do you prevent sulfur dioxide from being released?
flue gas desulphurization (FGD) with Lime (CaO)
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
What is the meaning of flue gas?
Flue gas is a type of exhaust gas that exits the atmosphere through a pipe often called a flue. Flue gas can be seen exiting power plants, a fireplace, oven, boiler or steam generator.
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.
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 charge in flue gas particle?
positive
What is in situ flue gas analyzers?
in situ refers that has not been moved from its original place of deposition. this type of flue gas analyzer fixed in stack.
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.
Flue gas analysis by Orsat apparatus?
An Orsat gas analyzer is a piece of equipment used in labs to analyze gas samples including flue gas. The Orsat analyzes the oxygen, carbon dioxide, and carbon monoxide content of the gas.
Do I open the flue for a gas fireplace?
When burning the firplace, flue must be open to avoid death/ illness from carbon monoxide.
