gas boiler Agent condensing chimneys


2015 INTERNATIONAL MECHANICAL CODE (IMC) - CHAPTER 8

The chimney or vent shall be resized as necessary to control flue gas condensation in the interior of the chimney or vent and to provide the appliance or appliances served with the required draft. For the venting of oil-fired appliances to masonry chimneys the resizing shall be in accordance with NFPA 31.

Condensing boilers achieve a much higher efficiency | Vaillant

How a gas condensing boiler functions. In a gas-fired condensing boiler the water is heated through the heat of combustion just as with non-condensing boilers. The resulting flue gases are normally passed into the chimney. As a result the energy contained in

The second and most obvious problem from cool chimney temperatures is the condensation of water vapor inside your chimney. As odd as it may seem the combustion of any hydrocarbon-and gas is a hydrocarbon-results mainly in carbon dioxide and water vapor. In fact the average furnace puts about 1 1/2 gallons of water into your chimney every hour!

Condensing boilers | Jeremias Group - chimney systems

The exhaust gas are cooled well below 120ºC hence the maximum condensate happens in chimney. The condensate then flows along the internal wall of the pressure-tight pipe back to the boiler for disposal. The condensate is acidic and decomposes base metals. Earlier used boiler and exhaust gas pipe material is hence not sufficiently corrosion resistant.

The OLIflex D.P. Inox 25 system is used principally for both the discharge of the products of combustion from domestic and industial boilers wood and pellet stoes and fireplaces. D.P. Inox 25 is resistant to the soot fire (G) and the maximun operating temperature is T 600° and the product must guarantee a perfect seal against acidic condensation (corrosion class V2) in dry and wet conditions.

Boiler-Venting Considerations - Heating Help

Aug 13 2015 · The boiler flue gases could condense until the stack gets warm causing rollout. Once the stack was warm the draft could be very high. A good rule of thumb is that a draft control should be used if the chimney is over 30 feet high. The draft control may range from a barometric damper to a sequencing draft control.
