In collaboration with harbin zhongneng automation equipment company ltd,, sas an industrial automation company china supples zndhq-20-z high energy arc ignition system for fuel firing system. Some electrical specifications include:zndq-20-z he ignition exciter - ignition energy - 20j; input voltage - 220 v ac ±10%; output voltage - 2500 v/dc; spark rate - 10 spark/sec; duty cycle - 30/60; spark rod length - 500-4000 mm; allowable maximum temperature at spark rod - 700ºc [continuous]; and igniter cable length - 1500-6000 mm. Following are some technical features of the hea igniter:this is a capacitor discharge system which conisists of a semiconductor he spark rod, he ignition exciter and ignition cable. It can directly ignite light diesel oil, heavy furnace oil, and any hard to ignite fuels. It has high spark energy, higher contamination and moisture resistance, and deposit resistance. This hea ignition system shall be supplied with advance/retract mechanism for higher capacity multi fuel and multi burner furnaces. The spark rod actuator advances the spark rod into atomised oil spray zone in furnace, to start ignition operation. When he ignition exciter is energised, it generates high-volt dc ignition pulses that goes to the spark rod through ignition cable and produce high energy spark at the front end of the spark rod for fuel lighting. After the ignition is completed, the spark rod is retracted to its guide tube.
