This unit, with Programmable Logic Controller (PLC) as its core, and oversea-introduced Ultraviolet Flame Detector as its main equipment, can perform automatic ignition in industrial furnace, and automatic detection and control in the flaming course. Its direct wiring with DCS can realize the functions of operation on the spot and outward output. It’s featured by sensitive motion, stable function, reliable performance, easy operation, simple assembling, and minimum troubleshooting. It can also adapt to various users’ requirements and meet the needs of ignition and flaming control in all sorts of burning furnaces and industrial furnaces. Being designed to be suitable for in-door as well as out-door installation, this unit is an ideal ignition and flame control equipment for all sorts of burning and industrial furnaces, and can perform automatic ignition and automatic flame detection for various coal gas, natural gas, diesel oil and heavy oil burners. Working Principle and Features When outward ignition conditions are fully met, and the ignition unit is ready, press the start button, open the assistant gas burner and assistant flame air valve, and close the drain valve; at the same time, high-pressure igniter is fired, and the assistant burner is igniting. After a period of time delay, the ignition of the high-performance igniter will be stopped, during this period, if the assistant burner flame detector detects flame, the assistant burner flame need to be waited for steady, and after the signal of allowing the main burner to be ignited is transmitted to DCS, then the DCS can open the main burner gas valve
