Multi Flame Burner

Raadman Water Tube Burner for Multi-Burner Boilers

To achieve higher capacities, use several burners in industrial water tube burners. In Industrial boilers, the simultaneous use of two burners is common, the flame shape of each is adjusted using air register vanes and swirler. These boilers have a common air box that the whole boiler air enters this air box and by adjusting the air register and swirler the shape of flame and the heat capacity of each flame will be adjusted.The shape of the flame is such that each burner has a separate small flame, but eventually all burners will have a single large flame.

As a result of many observations of multiple-burner, oil and gas firing equipment, on a wide range of boiler designs, it has been concluded that the proper airflow distribution to each burner is essential in order to control fame shape, fame length, excess air level, and overall combustion efficiency. Proper airflow distribution consists of equal combustion airflow between burners, uniform peripheral velocity distributions at the burner inlets, and the elimination of tangential velocities within each burner. If the unit has been designed with wind box FGR, the O2 content must be equal between the burners, and this is accomplished by balancing the FGR distribution to each burner.

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.

Dual Block 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, F300K

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.

Ignition technology

The most powerful ignitors are based on high energy systems developed over decades of experience in applications requiring safe and reliable operation, such as power generation plants and steam generating utilities.

The High Energy ignition systems ensure a number of robust intermittent sparks realized by the energy accumulated by a capacitor, providing more powerful ignition capacity than high tension arc electrodes. The Ignitors includes gas electric ignitors, light oil electric ignitors, without or with premixed air, suitable for continuous operation, as well as the direct spark ignitor for light up of heavy oil.

Usually, the igniters are an integral part of the supply of burners or combustion systems.

The ignitors can be supplied with in-built flame scanners or ionization flame rods, with automatic retraction drivers and with power supply units for installation in any environment and hazardous area. High Energy Electric Ignitor has been capable to withstanding to every temperature which could be present inside wind box and which can be up to 350 °C, and the discharge head itself must withstand to the very high radiation temperature close to the burner flame. The ignitor consists of three main parts, namely: Control Box, in which the power for the discharge is generated High Voltage Armored Cable, used to carry this power to the ignitor itself The Special Ignitor End, at which the discharge occurs across a semiconductor gap We can provide ignitors for a wide range of application and for any kind of industrial process as industrial boilers for steam/ power generation which burners where installed on boilers front wall or at boilers corners (tangential combustion), refinery or industrial furnace, thermal oxidizers and process heaters and so on.
