For the current MD6/7 test program, additional boiler capacity is needed. That is why we have a retinal boiler on site to provide more steam to the reboilers. The rental boiler will be on site at least for next two month. This safety nugget is trying to remind us the boiler safety.
In most facilities, boilers are the device with the most potential for disaster. The boiler is on the top of the FRI critical equipment. There are four major categories of catastrophic failures with the boiler: melt down due to low water level conditions,thermal shock caused by water flashes, combustion explosions, and high steam pressure due to excessive steam buildup.
Following are some of the operational measures to ensure boiler safety:
