| Abstract: | Regarding the problem of secondary air gate wearing in 1 065-t/h CFB boilers with no external fluidized bed heat exchanger (HG-1065/17.5-LMG, single firepot and double air distribution plates) which is independently designed and implemented by Harbin Boiler Company Limited, different measures have been tried in practice through the analysis of the air gate structure and the wearing mechanism. Eventually by installing wear-proof devices at the secondary air gates, we are able to address the wearing problem effectively, which may cause the boiler tube rupture and affect the boiler’s safe long-term operation. |
