As a fundamental component in manufacturing processes, burners play an essential role in supplying thermal energy. Their proper and safe operation relies on several factors,
Fired heaters stand out as one of the most crucial heating systems in petrochemical and chemical industries. They serve a critical role in industrial operations,
RLGB-M Series or RAADMAN Modulating dual fuel burners, covering a firing range from 700 to 17000 kW, are designed for a wide range of domestic and industrial applications. These Industrial burners have been tested and evaluated based on Iran national standard ISIRI-7595 (BS-EN 676) and ISIRI-7594 (BS-EN 267) for gas and oil operation respectively. According to performed experiments, the values of CO during low excess air operation is lower than 30 mg/kWh (in some cased very close to Zero). The precise design of their combustion head results a full gas-air mixture that guarantees high efficiency levels in all various applications. These Monoblock burners are equipped with LAMTEC and SIEMENS control system with capability of full air/gas ratio control throughout entire burner operating range as well as devices of well-known European companies such as Dungs, Kromschroder and Suntec. Burner superior design accompanied by high quality electronic devices have also resulted a further improvement in boiler’s performance in order to decrease fuel cost and emissions.

Generally, two types of atomizing principle are utilized in Raadman modular oil burners:
All Raadman pressure based atomizing modular oil burners are equipped with a burner lance and a fly-back oil atomizer. The burner-lance is especially suitable for use in or on an oil burner and is designed to operate spill back atomizers with integrated shut-off needle. The strong spring on the actuating rod pushes the needle in closed position. This ensures a reliable shut-off under all circumstances.
Fuel, branched off from the supply line actuates the piston for opening, either controlled by two external solenoid valves or by one 3/2 solenoid valve. The piston has a fixed travel. While opening, the needle inside the atomizer is retracted in the correct position by means of a spring at the back of the atomizer against a fixed stop on the needle itself.
During the pre-purge period of the burner, the needle is keeping the orifice closed and the fuel circulates through the lance at pre-set supply and return pressure. On energizing both solenoid valves and the 3/2 solenoid valve, even after long idle intervals, there is immediate atomization guaranteeing perfect ignition.
The burner-lance is suitable for supply pressures from 20 up to 40 bar and fuel temperatures up to 140°C.

All Raadman air/steam atomizing modular oil burners are equipped with a special burner lance and an air/steam atomizer. The burner-lance is designed to operate 32-Y atomizers with compressed air or steam.
The strong spring on the actuating rod pushes the needle in closed position. Compressed air, controlled by an external 3/2 solenoid valve, actuates the piston for opening. The piston has a fixed travel, pulling the needle in the correct position when it opens.
During the pre-purge period of the burner, the needle is keeping the central orifice in the reverse disc closed. On energizing the 3/2 solenoid valve, even after long idle intervals, there is immediate atomization guaranteeing perfect ignition.
The burner-lance is suitable for supply pressures up to 16 bar and fuel temperatures up to 140°C.
