The combustion process requires three essential factors: air, fuel, and an initial energy source. In small burners, a direct ignition system can be used to
As the dominant energy source for decades, fossil fuels contribute heavily to pollution and are limited in supply, making them incapable of sustaining long-term energy
Raadman gas and dual fuel burners are suitable for the following utilization.
Designed in accordance with ISIRI-7595 and ISIRI-7594 Iran national standard (equal to the BS-EN676, and BS-EN267 European standards).
The following methods of regulation are available for Raadman-Staging (Monoblock) burners:
Gas/oil: Two or Three stages of operation
Air humidity: max. 80 % relative humidity, no condensation.
The combustion air must be free of aggressive substances (halogens, chlorides, etc.) and impurities (dust, debris, vapours, etc.)
The emissions have been measured in various models at the maximum output, according to DIN-EN 676 and DIN-EN 297 standards.
The values of CO and NOx during burner operation are lower than 30 and 120 mg/kWh at 20 % excess of air for normal versions and, lower than 20 and 80 mg/kWh for Low NOx versions (LN series). consequently, the burner’s NOx class of II and III is reported and approved for normal version and LN Versions respectively.
LN versions have a higher rate of mixing during their operation. This results in a further decrease in the flame length and an increase in the flame diameter.
The flame dimensions which play an effective role in the burner efficiency and influence their compatibility with the boiler combustion chamber geometry, are presented in the above diagram.
The Raadman burners can be appropriately selected for all boilers which are designed according to the BS-2790, BS-855, EN-303, and BS-EN 12953-3. It is recommended that a flame fill 90% of combustion chambers at its maximum output.
According to the BS-EN 676, the valve proving system shall be used in burners with a capacity above 1.2 MW. Consequently, MADAS-MTC10 or DungsVDK200 valve-proving systems are highly recommended.
On boilers with hinged doors, the valve train must be mounted on the opposite side of the boiler door hinges.
Break points in the valve train should be provided to enable the door of the heat generator to be swung open. The main gas line is best separated at the compensator.
The valve train should be properly supported in accordance with the site conditions. See the Raadman accessories list for various valve train support components.
