现今理论和试验的研究已能足够正确地确定出单排管子和管束中第二排管子在含灰气流中的磨损。通常认为,最大的磨损是在错列管束的第二排管子。然而运行经验表明,锅炉的故障也常由管束纵深部位的管子磨损所引起。 Current theoretical and experimental studies have been sufficiently accurate to determine the wear of the second row of tubes in a single row of tubes and tube bundles in an ash-containing stream. It is generally accepted that the largest wear is in the wrong row of tubes in the second row of tubes. However, operating experience shows that boiler failures are also often caused by tube wear in the depth of the tube bundle.
