Visual Inspections

Using access provided by the utility, our furnace internal inspection service starts inside the furnace, proceeds through the screen tubes, into the radiant surfaces and pendants, and through the backpasses to the economizer. Each external surface of each element is inspected for alignment, distortion, damage, excessive corrosion, and erosion. Tube shields, hangers and tube spacers are inspected for integrity and damage. Deposit samples are retrieved from each section and analyzed to determine composition. The complete report includes a full compliment of photos, lab reports, inspection notes, and conclusions.
