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 causes sooting in gas water heaters?
Possibly the boiler is firing oil and thus the soot from the oil is spilling back into the gas flue
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.
Is the flue a virus?
no that's flu
What is the charge in flue gas particle?
positive
What is the correct flue classification for a solid fuel boiler when connected to a brick flue?
class 1.
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 is the typical flue gas temperature of a category 3 furnace?
120
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.
Use Flue in a sentence?
the flue pipe from my boiler runs directly to the hole in the chimney
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 causes small external oxidation sites on a boiler flue that connects directly to the chimney?
plumbing your toilet into the boiler
What is an atmospheric boiler?
ATMOSPHERIC BOILERa boiler on which combustion air/flue gases are drawn through the boiler without a fan.(Taken directly from the Crown Boiler Co. web-site.)
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.
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 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 effect will blocked flue have on the boiler?
The combustion air will not be able to go out the chimney. Since it has to go somewhere it will leak out the boiler into the boilerroom. If the boiler is air tight the pressure inside the boiler furnace will become high enough that the air will surge or run backwards out the forced air fan. This could lead to combustion outside the boiler, explosion or at least filling the boiler room with smoke and poisonous gasses. The flue on our gas fired hot water system once became jammed shut. It was the smell of incomplete combustion that alerted me to a problem. If it had happened when everyone was asleep or no one was home, the house would have filled with carbon dioxide.
