| Fly Ash Product Coolers |
ALSTOMs Gas / Product Cooler incorporates a design whereby hot flue gas flows through the tubes (FGTT) and cooling water flows over the tubes in multiple cross-counterflow passes. This Schack® FGTT construction has wide acceptance in dirty gas applications. The high velocity particulate laden gas flow within the tubes is parallel to (rather than normal to) the heat transfer surface. This reduces erosive impingement, which would limit life. In addition, each tube inlet is fitted with an erosion liner to prolong equipment life and also reduce required maintenance.
