The high temperature of flue gases is a major concern to me due to the fact that Schedule 40 PVC pipe and fittings are only rated for 140 degrees Fahrenheit. I think we, in New England, are going to see PVC failures in the near future, directly related to the high flue gas temperatures of the new high …View More
Probably one of the most commonly available energy sources, yet one of the least utilized, these sources vary in temperature from hot process industry flue gases at more than 1000 °C down to exhaust ventilation streams or refrigeration exhaust at 35 °C or lower, e.g., gases in a precombusted state, such as emissions from natural decomposition of organic waste.View More
Giardiasis is an infection of the small intestine causing diarrhea, gas, bloating, nausea and stomach cramps. Influenza (flu) child. The seasonal flu is a common viral infection that causes fever,View More
Nov 15, 2004 · Can anybody help me on this. Our firetube boiler has a progressive increase in flue gas temperature due to the formation of unburned residue or soot inside the boiler. We have already check the flue gas analysis and its corresponds to the standard setting. CO2 = 12-15%, O2 = 3-5%.View More
This problem is caused by hot gases cooling too quickly in the flue. As the hot gasses cool, the moisture in the gases condenses and start dripping back down the flue. Typically, there is a combustion issue or bad flue design.View More
May 13, 2003 · There are acording to my experience 2 main reasons for high flue gas temp. Increase in energy input like higher flame temp.,increased fuel capacity etc. Or reduction of heat transfer due to tube fouling (deposits), change in the product flow or specification. RE: High flue gas temperature.View More
Stack effect or chimney effect is the movement of air into and out of buildings, chimneys, flue-gas stacks, or other containers, resulting from air buoyancy.Buoyancy occurs due to a difference in indoor-to-outdoor air density resulting from temperature and moisture differences. The result is either a positive or negative buoyancy force. The greater the thermal difference and the height of theView More
The combustion flue gases inside the flue gas stacks are much hotter than the ambient outside air and therefore less dense than the ambient air. That causes the bottom of the vertical column of hot flue gas to have a lower pressure than the pressure at the bottom of a corresponding column of outside air.View More
The main reasons for the higher flue gas temperature are. High flue gas exit temperature from boiler; Erosion of heating elements of Air preheater. Clogging of heating elements. The reasons for high flue gas exit temperature are. a. Dirty furnace. b. High moisture coal. C. High secondary air.View More
Jan 22, 2020 · If you have an overdraft situation, then you may be running a higher stack temp than you need. Solutions are to install either a manual or barometric damper in the stove pipe to slow things down. At the beginning stages of a fire, wood put off more gases (flames) which tend to be long and reach up into the flue causing higher temps.View More

Mar 15, 2019 · By Russ Chapman March 15, 2019 Technical Resources No Comments. Many operators of industrial furnaces are losing significant amounts of energy because of too much air entering the furnace, resulting in heat loss through flue gases. The excess air results in oxygen that isn’t consumed during combustion, and this oxygen absorbs otherwise usable heat and carries it out of the stack.View More
The flue-gas temperature of a typical boiler could be anywhere in the range of 300 to 500 degrees Fahrenheit range. As a result, the extra oxygen could have entered the boiler at 70 degrees F and exit at 400 F. The extra oxygen reached this temperature by receiving fuel energy – in other words, fuel was purchased to heat the extra oxygen.View More
Learn what problems can cause this rise in exhaust gas temperature in order to enable troubleshooting and so that taking care of these factors results in restoring normal temperatures. Exhaust gas is by-product of combustion and is naturally at a high temperature.View More
The flue gas exits the cyclones to a plenum chamber in the top of the regenerator. The hot flue gas holds an appreciable amount of energy. Various heat recovery schemes are used to recover this energy. In some units, the flue gas is sent to a CO boiler where both the sensible and combustible heat is used to generate high-pressure steam.View More
