The Submerged Scraper Conveyor Project-Bottom ash removal is a critical element in the operation of a utility power plant.  The Submerged Scraper Conveyor (SSC) is one of the primary means to remove this ash.  Ci Metal Fabrication took on the task of fabricating this complicated piece of machinery.

The difficulty of the project was compounded by the 127 foot long SSC which had to be skewed in order to fit beneath the existing power plant located in New Mexico.  This created challenges in engineering and designing for our longtime customer (an OEM supplier for the utilities industry) and in fabrication for us.

The twisted SSC had to mate with a transition chute that was squared up with the bottom of the boiler.  There were no detail drawings to outline how this should be done.  We designed and fabricated samples of the structural steel supports and plate where the SSC and chute would meet.  We provided the samples to our customer during a prefabrication meeting.

The samples were approved, and the SSC and transition chute were shipped on time.  The power plant personnel were amazed by the ease in installation.  The transition chute was attached to the furnace bottom and the skewed sections of the SSC were fitted flawlessly beneath it.  They were able to complete the installation within the allotted outage span.
