Refinery and petrochemical units, as critical pillars of the energy and chemical industries, depend heavily on thermal systems, particularly burners. Fired heaters are used to
Boilers serve as fundamental components in heating systems, supplying the thermal energy essential for a range of industrial and commercial applications. The burner, as the
In today’s world, energy conservation reducing environmental pollution are top priorities across various industrial sectors. Burners, as the central components of industrial furnaces and boilers,
In nozzle mixed burners, fuel and air enter the combustion head from independent paths and are mixed by diffuser and flow swirling blades. The idea of designing premix burners has been formed to increase the Homogeneity of mixture, and consequently increases the combustion quality of the burner and reduce NOx and CO emissions.
The mixing head has been innovatively designed for complete mixing of fuel and air using staging mechanism and a set of flow rotating blades. The fuel and air are injected from independent paths and are mixed through two rows of rotating blades, due to the creation of vortices and turbulence in the flow.
Full electronic modulating burners are designed to safely operate throughout its firing range from high fire to low fire. The most common turndown ratings in PB-Series burner are 1:5 up to 1:6. High turndown is used to reduce the burner cycling and maintain a consistent temperature or pressure in the boiler. This is crucial if the boiler is used in an industrial process that requires a consistent temperature or pressure. PB-Series burners are equipped with an electronic microprocessor management panel, which in post-mixed burners controls the air damper and fuel servomotors and in pre-mixed burners, using PWM signals, controls fan rotational speed. Using electronic modulation, hysteresis is prevented by the precise control of the separated in independent servomotors and the software linked by can – bus. The Siemens LMV26/37 and Siemens LME71, as the most popular brands used in Raadman Post-Mixed and Premix burners respectively. This burner Control System combines the benefits of an electronic fuel/air ratio controller with an electronic burner control unit.
