Nov 29, 2018 · The gas boiler. Gas boilers - which can be fuelled by natural gas or propane - offer several advantages: they are easy to install, fairly low-maintenance and are one of the most eco-friendly energy compared to other heating sources. An additional benefit if opting for natural gas as the fuel is that it is the cheapest fuel sources as of todayView More
Flue gas inlet boiler - kuurnsezichten. The exhaust flue gas temperature was 80 °C. In the experiment, the boiler output flue gas temperature is also kept at 80 °C. And according to different return water temperatures, the condenser inlet flue gas temperature changes from 50–60 °C.View More

I'm sorry if this topic has been discussed before. We bought a new boiler in England intending to use in a new build in France. After placing the boiler on the wall and joining all the piping( but not putting any water or gas through it) we have been told the gas authoritiy won't sign off the system because the boiler wasn't bought in France.View More
The residual heat contained in the flue gas downstream of the condenser is used to heat and evaporate water. This moisture is transferred to ambient air and directed to the boiler as hu-midified, pre-heated combustion air. This increases the mois-ture in the flue gas and the heat recovery in the upstream condenser. Fuel Boiler Filter Flue gas inletView More
A common trend observed is, as boiler is operated continuously, the measured outlet temperature of flue gases increases. After operation for a few months, significant rise in flue gas temperature and hence stack losses is observed. The reason behind this is, as a boiler is operated, scales are formed on the boiler …View More
The usual arrangement is to have a fuel oil supply available on site, and to use this to fire the boiler when gas is not available. This led to the development of ‘dual fuel’ burners. These burners are designed with gas as the main fuel, but have an additional facility for burning fuel oil.View More
The sensible heat that could be recovered from the flue gas by cooling it in a flue gas cooler (FGC) from the APH gas outlet temperature of 310F to the FGD inlet temperature of 140F is 43 to 46View More
May 12, 2010 · Hello, British Gas installed our new boiler. After stormy weather it became apparent that water gets into the flue pipe. It has an opening to allow air to get in. Unfortunately, it also lets in rain water, which is driven in by the wind. British Gas so far have said it is a fault with theView More
Per the 2015 IECC/IRC, Section R103.3/R106.3, Examination of Documents. The code official/building official must examine, or cause to be examined, construction documents for code compliance. This section lists the applicable code requirements followed by details helpful for plan review regarding the provisions to meet the requirements for "gas-fired boilers."View More
It consists of recirculating hot gas taken from the top of the furnace and reinjecting it through the bed of fuel in the furnace inlet zone with a recycling rate of 10-15 %. A scrubber-heat exchanger is used to condense the flue gases and to remove any remaining dust particles (after the flue gases have been cleaned in a multicyclone).View More
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.View More
Flue shapes, types and sizes. If you’re looking to get a new boiler or are discussing one over the phone with a heating engineer, prior to a boiler installation, then they’ll very likely want to know the shape and exit point of your existing flue. Fortunately, these questions are really easy to answer. Flue shape – it’s going to be either a square or round flue.View More
Jun 14, 2018 · Pneumatic Vane Damper Drives for Boiler Flue Gas and Combustion Air: A Superior Alternative to Electric Obsolete ID fan inlet damper drive. Pneumatic damper drives are excellent alternatives to electric drives because of speed, accuracy, and reliability. Pneumatic vane damper drives don't have gears or motor windings that slow down response orView More
Flue Gas boilers are the significant energy saving equipment, utilize the heat in flue gas from combustion processes or hot extract air from industrial processes to generate hot water or saturated steam Otherwise, the flue gas boiler could be used in oil gas fired combined cycle units, and take advantage of the high temperature flue gas heat discharged by gas turbineView More
Jun 19, 2019 · Flue Gas Recirculation (FGR) is the process of taking a portion of the flue gas from a combustion process and recirculating it back through a boiler or burner. When the process is used in internal combustion engines it is commonly referred to as exhaust gas recirculation (EGR).View More
The economizer is a bunch of horizontal water tubes usually located in the back pass or second pass (after the primary superheaters and reheaters) of the boiler through which the feed water enters the boiler to absorb the residual heat from the exhaust flue gas and transfer it to the steam production cycle. This process helps in improvingView More
Based on the flue gas composition and temperature, some adjustments can be made to tune-up the boiler and to determine the best air-to-fuel ratio to improve the boiler efficiency. Monographs are available to determine the overall boiler efficiency based on measurement of flue gas …View More
