Well, we made it through. We had the sootblower lance about 20 foot from the bottom before the cable failed and fell to the bottom ash. We're extremely happy with the effort since a lance falling from over 120 feet could have taken us off.
Thanks everyone for your words of wisdom!
We just cannot afford to wait for it to burn up and fall off on it's own. There have been a couple tube leaks in our system from sootblower lances falling and causing tube leaks on the bottom ash slope. We are good enough to have very long runs between forced outages, so waiting for an outage...
Thanks everyone for your input. The boiler that I am talking about is a Foster Wheeler Once Through Supercritical. It is a 900 MW unit with a max feedwater flow of 6.6 million pounds/hour.
I will explain more. We have a sootblower lance stuck in the furnace and it is bent 90 degrees downward so there is no way to get it back out through the port. At another plant in our system a lance broke free and caused a tube leak on impact. The idea is to attach a high temperature cable to...
