  • A thermodynamic approach on vapor-condensation of

    Jun 01, 2008 · To estimate quantity in moles of vapor-condensed deposits from flue gas at 350–550 °C, which correspond to the tube wall temperatures of most practical boilers, equilibrium flue gas composition was firstly obtained at 650–950 °C, and the gas species in these gases were quenched to cold tube walls by conducting another series of equilibrium …Learn More

  • Managing Condensate for Condensing Boilers

    Flue gas starts to condense when it drops below its dew point of 55°C. This is why condensing boilers are designed to accommodate a return water temperature of 54°C or less. It is this resulting condensate liquid that is acidic and requires treatment to avoid damage to piping systems, sewerage systems and other items it may come in contact with.Learn More

  • Flue Gas Condensing Temperature - HVAC-Talk: Heating, Air

    Mar 13, 2008 · Flue gasses condense at temps much warmer than 140. You should see flue temps of around 400* to 500* for nat gas. Chances are, the boilers are underfired. Set it up with a combustion analyzer and make sure the draft and flow rate is ok. Flue gasses condense at temps much warmer than 140.Learn More

  • Myths and methods for protecting boilers against flue gas

    Nov 27, 2017 · Here's a statement that is easy to remember: All boilers that aren't designed to operate with sustained flue gas condensation should be protected against sustained flue gas condensation. The latter includes almost all cast-iron sectional boilers, steel boilers and copper tube boilers. These boilers are not intended to operate with sustained flue gas condensation.Learn More

  • What is a Condensing Boiler and How Does it Work?

    A standard boiler gives off waste gases through a flue and into the atmosphere at a high temperature of over 200 degrees, where this is significantly reduced in a condensing boiler. The heat input is pretty much the same at about 250 to 350 degrees, but a condensing boiler has a much more efficient way of working compared to other types.Learn More

  • Case Study: Condensing economizer in boiler

    Typically heat loss though flue gas in natural gas fired boiler is in range of 11-15%, considering both heat being carried out though water vapour and flue gas exit temperature. If Flue gas is cooled to below condensation temperature, both latent and sensible heat present in flue gas …Learn More

  • The Concept of Condensing Boilers

    In a traditional boiler, the flue gases exit at a temperature of more than 120ºC/248ºF. In a condensing boiler, the flue gases exit at much cooler temperatures (i.e., between 50ºC/122ºF and 80ºC/176ºF). In order to condense the gases in the venting, the flue temperature must be lower than the dew point temperature. AtLearn More

  • Flue gas filtration of biomass boilers | G&G filtration

    The filtration device is thermally insulated over the entire casing and is equipped with an electric heating cable for tempering the filter housing and preventing condensation of flue gases at the moment of starting or stopping the boiler at a low flue gas temperature.Learn More
