As a fundamental process, combustion plays a crucial role in supplying the energy needed for everyday life and industrial applications. Understanding its basic principles is
Energy must be applied in a controlled and safe way in many industrial and thermal processes. One of the most common methods of providing thermal
Heating is one of the fundamental requirements of greenhouses that directly impacts plant growth and production. As controlled environments designed for plant cultivation, greenhouses must
Raadman pre-mixed burners equipped with a centrifugal fan and a brushless electromotor that guarantee high performance, low sound emission and optimized speed variation. The motor speed variation controls the regulation of gas delivery. Pre-mixed burner gas train consist of a pneumatic proportioning multiblock gas valve that regulates gas input by fan pressure feedback.
Thanks to standard mixing venturis, Gas and combustion air are completely mixed before the fan wheel. Using the PWM pulse and, as a consequence, controlling the rotation of blower, the mixture is transferred to combustion area. Finally, A well spark, results a pre-mixed flame with minimum pollutions.
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.
PACKMAN Company was established in February, 1975. The company has started its activity in the field of producing High-Pressure Vessels such as Hot-Water Boilers, Steam Boilers, Pool Coil Tanks, Softeners and Heat Exchangers since 1984.
