Be an interesting person and come up with an interesting question — let’s test whether it’s possible to measure the liquid level in a boiler using horizontal measurement. . . :P Fault description: There is a high-pressure steam boiler at 14 MPa, equipped with a differential pressure level gauge via a balancing vessel. When the boiler is not in operation, water is added and removed, and the differential pressure gauge reads normally. Shortly after the boiler is started, the reading of the differential pressure gauge stabilizes and changes very little. After the fever subsides, when water is added and then removed again, the reading of the differential pressure gauge will return to its normal range of variation. Check the balance vessel: the pressure reduction and cooling in the gas phase are normal, the vertical pipe is full with no blockages; the pressure reduction and cooling in the liquid phase are also normal, with no blockages. The power supply, cables, and DCS cards have been checked and are all in good condition. The meter was taken apart and sent to the Provincial Thermal Engineering Institute for inspection, and it was found to be in good condition. . . After inspection, the gauge was installed on the boiler; the problem persisted even after it was started up. The meter was taken apart again and sent to the provincial metrology institute for inspection, and it was found to be qualified. Divider line---------------------------------------------------------------------------------------------- The designers from those days, whether they had worked there for 3 years, 13 years, or 30 years, lined up to go to the site and take care of this boiler’s differential pressure gauge, trying to diagnose any faults. The experts from the manufacturers, who had been producing and selling such gauges for decades, also lined up to go to the site to deal with the issues related to this boiler’s differential pressure gauge. It’s a pity that neither group was able to determine the cause of the faults, nor were they able to fix them. Back then, Haiyou turned to Haichuan for help, but no solution was found. So today, I’ll be a fun person and pose an interesting question to test you: Can you measure the liquid level in a boiler properly? :P Divider -------------------------------------------------------------------------- The days are passing quickly; 20 days remain. Tomorrow is April 19, 2018. Answers will be announced tomorrow, and the money will be distributed then – money, money, money {:2_36:}.
