The radiation electric heater in Luoyang Zhongsi has failed

The radiant electric heaters supplied by Zhenjiang Dongfang Electric Heating to Zhongsi seem to have been the first of their kind to be introduced to the market; their power output was not high either. So why did they break down after being used for only a short time? Well, after all, it’s a company with experience in manufacturing small household appliances, and the electric heaters that used plug-in heating elements they previously produced had caused problems for many companies.

This maintenance session for Zhongsi is supposed to be carried out once a year; it was originally scheduled to start in August, but now it’s starting at the beginning of September instead

Logically, electric radiant heaters shouldn’t experience overheating of their heating elements. Do you know what the reason is?

I’m from Zhongsi, that is, Luoyang Zhongsi mentioned in the moderator’s post. However, what the moderator said isn’t true; those who say that production was halted for maintenance because of this matter don’t understand the actual situation of our company any better. We use a fixed-bed hydrogenation production line, with a maintenance cycle of 3 to 4 months once. This radial electric heater is indeed being used for the first time; it has been in use for nine months now. There was indeed one issue with the heating element at some point, but it wasn’t a problem that occurred during normal operation. Instead, it was discovered that there was an abnormality in the heating element core during startup after routine maintenance of the system. The issue occurred at the cable connection, and normal operation was restored after less than two days of replacing the cable spare parts. It seems that many things have ended up in this state due to misinformation. For us manufacturing companies, we use those products that are effective; we definitely avoid those that are not useful or those that don’t offer good value for money. I think all companies should do the same.

Initially, a failure in the radiation heater caused the plant to stop operating; later, the manufacturer came to fix it. However, to this day they have not been able to explain the cause of the damage. It could be a design flaw, as a certain number of units were damaged and all of them had to be replaced. What worries us the most is whether a damaged heater will have an impact on the pressure-bearing pipes containing the main materials inside. Every time I pass by the heater during a inspection, I’m a bit worried about leaks.
