Flue Gas - an overview | ScienceDirect Topics

For these cases flue gas called synthetic gas (syngas) in some cases is generally reducing and contains gaseous H 2 S resulting from sulfur in fuel. For some industrial boilers slightly air-deficient combustion is favored at their furnaces in order to minimize formation of gaseous nitrogen oxides.

Pollution Control in Boilers | Just Venting

Oct 30 2019 · The selection of fuel to burn in the boiler is the first opportunity to reduce flue gas contaminants. For example natural gas burns cleaner than fuel oil medical waste or biomass and produces the least amount of pollutants in its flue gas. Natural gas is considered a low-nitrogen fuel and yields very little NOx as a by-product of combustion.

Flue gas recirculation | clean environment | emissions ...

Feb 24 2016 · Flue gas recirculation is used mainly to reduce the NO (nitric oxide) content in the exhaust gases from thermal combustion processes -as the use from industrial burners- and which is referred to more broadly as NOx.. NO CO (carbon monoxide) and SO2 (sulfur dioxide) are the elements that are heavily involved in todays environmental problems in many industrialised economies especially in ...

High Pressure Boiler: What is it? Types & Characteristics

Flue Gas Passes: The number of passes flue gas makes before leaving the boiler is a good method for examining boilers. As the gas moves around the boiler it cools which changes its volume. The more passes it makes increases the efficiency of the boiler and increases the gases velocity.

What Causes a Boiler to Smell Like Gas? | Kieron Murphy

Natural gas includes an additive that makes it smell like rotten eggs so that you can detect when you have a gas leak while liquid propane smells like you would expect gas to smell. Therefore if you can smell gas around your boiler its likely to be that liquid propane is leaking from the boiler.

Measuring Boiler Efficiency with a Flue Gas Analyser ...

A flue gas analyser (sometimes spelled flue gas analyzer) is a very useful tool which can be used to measure the efficiency of a boiler. Boiler efficiency can depend on a number of factors many of which can be tweaked. A flue gas analyzer will also mitigate the impact that you are having on the environment.

Flue Gas - an overview | ScienceDirect Topics

The condensing economizer is on a by-pass of the flue gas flow from boiler. The exemplary flue gas temperature entering the condensing system is 150°C. This system is designed to handle only a part of flue gas. In the described example the flue gas leaves the condensing economizer at 50°C and the mix of two streams enters the stack at about 120°C.

What temperature should a condensing boiler be set at ...

A condensing boiler is one of the most efficient types of boiler. This is because it is able to recover virtually all the heat from the flue gases and use this to heat your home. For the boiler to work at its most efficient the heat exchanger needs to be equal to or below the dew point temperature.

A Flue Damper is a Must-Have When You Have a Boiler

Nov 29 2017 · A flue damper is incredibly useful when you have a steam boiler installed in your home. These heating systems make use of steam that is pushed through pipes into radiators of your home. When hot water is needed to generate steam the boiler will come on. When this process happens there is already air inside the pipes leading to the radiators.

The misunderstood barometric damper | 2013-02-13 | PM Engineer

A barometric damper is a great solution. High draft will pull the flue gases too quickly through a boiler not allowing the heat to be transferred into the boiler. The barometric damper is installed in the flue between the boiler and the chimney. It is set for the desired draft conditions using weights and adjustment screws.
