    Application Note: Flue Gas Analysis as a Boiler Diagnostic

    as a Function of Air/Fuel Ratio NO X (mg/m 3) Another NO x reduction strategy is flue gas recirculation, where a certain amount of flue gas is mixed with the normal air used for combustion. An O 2 probe mounted after this mixing valve can be used to control final O 2 going to the burner, resulting in a cooler flame that produces less NO x. Power

      When it comes to selecting a boiler based on the fuel it uses, it’s best to find a boiler that can operate on more than one type of fuel. For instance, Miura’s LX models can run on either natural gas or propane, which is part of what makes them one of the top eco-friendly boilers available. Meanwhile, Miura’s EX series of boilers can run

      Understanding Boiler Stack Losses - Forbes Marshall

      Air comes inside a boiler at ambient temperature, i.e. around 25- 40 Degree Celsius depending upon the location. After combustion, combustion products, i.e. Water vapor, Carbon dioxide and other gases depending on fuel composition are formed. These flue gases heat the water and then leave the system through a Chimney.

      How to Destroy a Boiler -- Part 1

      A gas/oil boiler has no inventory or bed of fuel. When you trip the burner, for all practical purposes, the heat input immediately stops. With solid fuel units, however, a fairly large mass of bark, coal, etc., is still on the grate and even though starved of air by the loss of the forced draft fan, these units have more "thermal inertia" and

      Flue gas - Wikipedia

      Flue gas is the gas exiting to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator.Quite often, the flue gas refers to the combustion exhaust gas produced at power plants.Its composition depends on what is being burned, but it will usually consist of mostly nitrogen (typically more than two-thirds) derived
