Soot blowing is done in air pre heater by a blower called swing blower which is different from half retractrable or full retractable or deslagger.
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.
Depends on your preheater, but in a modern preheater plant you will often feed 60% in the TAD and 40% in the kiln. KK
I think soot and smog come from the air pollution.
If you have an issue with furnace exhaust in your home and soot is exhaust. Please stop wasting your time here. That is dangerous. Call somebody! Nobody here can tell you what it is with out looking at it.
preheater is used to heat the air at Inlet of the furnace of Boiler By using Heat contents of Exhaust gases. This will minimize the fuel Consumption.
A thermal power plant is more efficient when energy can be captured for reuse. Air coming into the combustion are ignites the fuel more efficiently when it is hot. Air leaving the combustion area looses some of its heat to the steam system, but a significant portion of the energy is lost with the exhaust gases. The preheater takes these two energy conditions (one area needing heat and one having "lost" heat) and combines them in a heat exchanger (preheater) where the heat from the exhaust gases is used to warm the incoming combustion air.
Car not blowing air or heat
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.
blowing cool air, is the air only in your mouth... warm air comes from your lungs. temperature also varies by how open your mouth is while blowing air out
