What is the correct flue classification for a solid fuel boiler when connected to a brick flue?
class 1.
Where is a flue located on fireplace?
the flue is the part of the fireplace that goes from the firebox to the outside of the building.
What is chimney build up called?
Chimney build up is called creosote. You should clean your chimney regularly to remove the creosote from the lining of the flue.
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 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 should be the range of temperature of flue gases at outlet of air pre-heater?
The typical flue gas temp at the inlet to the air heater is about 650-750 DegF range.
What is the typical flue gas temperature of a category 3 furnace?
120
Why should the flue gas temperature be observed frequently and logged?
The flue gas temperature should be observed frequently and logged because it can provide valuable insights into the efficiency and performance of a combustion system. By monitoring the flue gas temperature, deviations from the expected temperature range can be detected, indicating potential issues such as incomplete combustion, heat exchanger fouling, or fuel supply problems. Logging these observations allows for trend analysis and helps in identifying patterns or abnormalities that may require corrective action to optimize energy efficiency and minimize emissions.
Can the flue be closed before the ashes are cool?
As long as there is combustion, the flue should be left open.
When should you change your wood stove insulated chimney?
You should change the flue if you have ever had a flue fire. you also can remove the base T and use a mirror to look up the flue. If the inside looks warped it should be replaced.
What is the function of economizer in bent tube boiler?
The flue gases, after leaving the main boiler and the superheater, will still be hot. The energy in these flue gases are used to preheat the already preheated feed water once more by means of the economizer. The economizer is a heat exchanger mounted in the first part of the chimney to improve the thermal efficiency of the boiler. In broad terms a 10°C increase in feed water temperature entering the boiler will give an efficiency improvement of 2% of last mentioned.
Should you close your flue when using a gas fireplace?
No. The flue must be open to allow the carbon monoxide to escape from the house.
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.
Should the damper be opened or close when operating the fireplace?
the flue should be opened
What is economizer in boiler?
Economizer is an accessory of boiler that recovers the waste heat from the flue gas blown out of the boiler. Thus it actually "economizes" the operational cost or in other words, improves the efficiency of fuel utilisation in the boiler. The temperature of the flue gases ( the mixture of burnt fuel & air ) depends up on the steam pressure ( temperature more precisely ). Higher the steam pressure generated, the higher is the flue gas temperature. Economizer is a heat exchanger which exchanges heat between water ( which is fed in to the boiler ) & the flue gas. It means it increases the temperature of the feed water using the otherwise wasted heat of the flue gas. So the water entering the boiler has higher temperature compared to the one without this economizer. This higher temperature of water requires less amount of heat to generate steam so the operation becomes "economical". Similarly the economizer can also work to heat up the air entering the boiler through the flue gas heat, instead of heating the water.
What should the fireplace flue's position be when the fire is lit?
It needs to be open when lighting a fire. Close it when not in use. If you have any doubt which is which, look up the flue with a flashlight.
How do you put flue in a sentence?
flue you
