The flue gas drying technology implemented in lean coal-fired boiler of Nanj ing Power Plant was introduced.Problems such as hot flue gas fan abrasion,deposited ash vibrancy,and insufficient output oc-curred on this boiler were investigated.Moreover,solutions for the above problems were put forward. Through fan type selection optimization,fan blade abrasion resistant treatment,reasonable arrangement of maintenance and other measures,the problems of fan blade abrasion and deposited ash vibrancy were well solved,and the service life of flue gas fan was significantly prolonged,the time and cost of maintenance were reduced,and the safety and reliability of bituminous coal pulverizing system in lean coal-fired boiler were ensured.
