Grid for intercepting solid particles circulating in a heat exchanger for cleaning, and control device for such particles using such a grid

摘要

The grill for removing cleaning solid particulates from a heat exchanger fluid flow has a frame (33) with moulded plastics grill inserts (36). The frame is formed by metal strips formed as plates (34) mounted in parallel with a regular spacing. The strips are held apart by welded cross spacers (35). The grill inserts are all rectangular and extend between pairs of plates.
