What is the reason for the automatic shutdown of the boiler combustion engine after ignition?
Whether in actual production or among friends who have heard about it, I have learned that the boiler combustion engine will automatically shut down after ignition, and many people are troubled by this; There are actually many reasons for stalling, and besides stalling, there are also other reasons that come with it. Today, let’s talk about the reason why the boiler combustion engine automatically stalls after ignition?
If the ignition is unsuccessful, no flame is formed, or the flame detector does not sense the brightness of the flame, the safety alarm system will be activated after approximately two seconds of safety time, and the starting process of the combustion engine will be cut off. And the fault red light will light up. When the ignition step of the boiler combustion engine fails, check if there is a problem with the oil supply system. Please stop the machine to check if the oil supply system of the boiler combustion machine is normal, if the circuit connections are correct, and restart the fire extinguisher after removing obstacles.
When in normal use, replace the oil nozzle, and then generally replace the elastic coupling and rubber parts on the coupling. After combustion, carbon deposits will attach to the boiler coils or heating elements, which will reduce the thermal efficiency of the boiler, seriously increase the back pressure of the boiler, and prevent the combustion engine from working properly. Smoking, welding, cutting, and other operations are strictly prohibited at the work site of the Odic combustion engine. A combustion engine is a machine that utilizes the atomization effect of fuel to completely burn in thermal equipment, such as heat treatment furnaces and boilers.
During the process of debugging the boiler combustion engine, it is necessary to be careful, quiet, and effective. Therefore, fuel density and speed directly affect the performance of the combustion engine. It is prohibited to use non explosive electric tools in the workplace of boiler combustion engines. Provide detailed instructions to customers on the precautions for operating boiler combustion engines. If the volume of the furnace or the diameter of the chimney is too small, black smoke may be generated during the combustion process. The nozzle may be too large. If the oil pressure is adjusted too high, the original furnace volume may be too large to accommodate the increased flame and burn. Sometimes black smoke may appear.
Before starting, please check if the oil circuit of the boiler combustion engine can be opened. Adjust the oil pressure appropriately according to the indicated oil pressure value. If the chimney is equipped with a baffle, please pay attention to whether it opens correctly. If the chimney is equipped with an exhaust fan, please note whether it is activated. Especially, flame detectors should be kept clean and free of water. Another thing to note is not to perform combustion engine debugging at night.
At this point, the flame detector will sense the brightness of the flame and the controller will enter a locked state. Perform cold simulation on the combustion engine based on the production line conditions. Observe whether all parts of the equipment are functioning properly during operation, and whether the flame detection and protection parts are functioning properly. Therefore, it is necessary to master the fuel density and speed during use to avoid unnecessary trouble. The combustion engine can only be restarted after the red light of the combustion engine is lit.
