Automatic ignition system and flame probe system

Abstract

This invention relates to the auto ignition and blaze detects system, it includes that: The auto ignition set for initiating ignition control signal, it discloses the corresponding channels according to the ignition control signal in this invention and holds the signal of the high lever voltage to blow up and export. The ignition transforms, it connects with the auto ignition set by the control relay for turning on power when auto ignition set cross the deferent amplificatory small signal of the high lever voltage in this invention and drives the control relay in this invention for suction and combination, also makes the direct current power to surge high frequently, enhance voltage and direct current voltage produced by the commutation. The ignition and the blaze detect probe connects with the ignition transforms and auto ignition set in this invention for igniting gotten direct current high voltage in this invention. It exports the blaze feedback signal to the auto ignition set in this invention, and watches the condition of the blaze produced by the blaze. This invention is the same with the pit-type industrial stove which can save heat, and so on, and it has this character in that auto ignition completely and blaze detect.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to an automatic ignition and flame detection system for double-delay automatic ignition of a heat preservation pit and monitoring the flame combustion state in the production of the heat preservation pit. Background technique [0002] At present, the heat preservation pits in iron and steel enterprises all adopt the mode of manual ignition. When the heat preservation pit needs to be ignited for production, two workers cooperate to ignite it. One of them opens the main gas valve, and the other uses a torch to extend from a fire viewing hole above the main burner to ignite it. This method one is to increase the operating strength of the workers, and the other is that when the atmosphere in the furnace is unknown, the risk factor is large. [0003] During the production of the holding furnace, when the flame is extinguished due to abnormal reasons such as low gas pressure, the gas val...

Problems solved by technology

[0006] Moreover, in the existing automatic ignition and flame monitoring system, the distance between the automatic ignition device placed in the control cabinet of the control room and the flame detector placed in the on-site heat preservation pit can only be 5-6 meters away. , will cause inaccurate measurement of fire detection signal attenuation

Therefore, the existing automatic ignition and flame monitoring system cannot realize long-distance ignition control
