FGR Technology

Flue gas recirculation (FGR) can be a highly effective technique for lowering NOx emissions from burners, and it’s relatively inexpensive to apply. Most of the early FGR work was done on boilers, and investigators found that recirculating up to 25% of the flue gases through the burner could lower NOx emissions to as little as 25% of their normal levels.
With FGR technology, consisting of temperature sensor and flue gas damper with actuator both connected on a flange, a portion of the exhaust (flue) gas circulates back into the combustion zone to decrease the flame temperature and reduce nitrogen-oxide (NOx).

When FGR is used, because of reduction in radiation heat transfer, boiler efficiency may decrease, typically in the range of 0.25 percent to 1 percent, depending on the amount of FGR added. Plant experience shows that the combination of low NOx burners with re-burning using FGR system, reduces the NOx level to approximately lower than 40 mg/kWh

Note: The housing arrangement is to be considered as viewed from the drive side of the fan. Subsequent alteration of the alignment of the fan to its base is not possible, as the two parts are welded.

Acoustic absorption refers to the process by which a material, structure, or object takes in sound energy when sound waves are encountered, as opposed to reflecting the energy. Part of the absorbed energy is transformed into heat and part is transmitted through the absorbing body. The energy transformed into heat is said to have been ‘lost’.

When sound from a loudspeaker collides with the walls, the sound’s energy is reflected, part is transmitted, and part is absorbed into the walls. Just as the acoustic energy was transmitted through the air as pressure differentials (or deformations), the acoustic energy travels through the material which makes up the wall in the same manner. Deformation causes mechanical losses via conversion of part of the sound energy into heat, resulting in acoustic attenuation, mostly due to the wall’s viscosity. Similar attenuation mechanisms apply for the air and any other medium through which sound travels.

Reliable Flame Monitoring

Flame monitoring plays a crucial role when it comes to reliability and safety.
Determination of the best method of flame monitoring takes into account not only the burner and the fuel to be combusted, but also how the system operates and the conditions inside the combustion chamber.

Heat generators with one flame per combustion chamber are easier to monitor than those with multiple flames. In the latter case, it also depends whether the flames are firing into the combustion chamber from the same or opposing directions.

Biomass plant and waste incinerators need a flame monitoring system that is not affected by extraneous flames.

DB series are for plant with multiple burners firing from different directions into a single combustion chamber, and for process plant with various flame sources. The flame scanners monitor each flame separately via up to ten load-dependent switching thresholds for each fuel.

Lamtec – F200K

The compact flame scanner is composed of a cylindrical casing comprising an axial light incidence aperture, a processing status indicator at the rear of the unit and operational controls which can be accessed by removing the cover. The device is connected through an integrated standard plug and using a connection cable required for this with coupler.
