A Member of DURAG GROUP Introduction For more than 65 years Smitsvonk has been making low-tension high-energy ignition and control systems for industrial combustion processes. These electrical and electronic ignition systems are applied world-wide. They are characterized by a high degree of reliability under demanding conditions. Ignition is not effected by dirt, humidity, extreme temperatures or aggressive gases. The company was founded in 1947 by Mr. Wietze Beye Smits. He was the inventor of the High-Energy (Low-Tension) Ignition System. Before the production of industrial ignition...

A Member of DURAG GROUP The Smitsvonk Ignition Principle Smitsvonk’s low tension high energy ignition system is designed to meet the requirements of reliable ignition for many industrial applications. The system is based upon the principle of a capacitor discharge over a special discharge surface. This surface consists of an isolator with semiconductor properties. The isolator and positive and negative electrodes are integrated into a high temperature resistant spark plug. When a charged capacitor is connected, it will be discharged via the spark plug producing sparks, even under wet or...

A Member of DURAG GROUP Flare Ignition Systems Flaring systems in a refinery, petrochemical plant or steel plant ensure the safe and efficient disposal of relieved gases. A flare is expected to operate twenty-four hours a day. The flare system must be in service for several years without a need for maintenance. Therefore proper design and operation are extremely important. Ignition of the waste gases can be done by pilot burners (flame) or for some applications by ignition lances (spark). The ignition system must reliably ignite the waste gas of the flare. If the ignition system fails,...

A Member of DURAG GROUP Pilot Burner Ignition of waste gas from pipe flares, air and steam assisted flares and ground flares For most flare systems the pilot burner can not be accessed for service. Maintenance or replacement is not possible while the flare is in operation. To safeguard operation, Smitsvonk’s pilots provide reliable ignition and stable burning even under the most difficult climate conditions. High energy ignition Ignition by three integrated spark plugs Long lifetime, longer maintenance intervals Insensitive to moisture and dirt Complete delivery; cables, junction boxes and...
