Zusammenfassung:	An anti-abrasion and explosion-proof device for a coal economizer of a power generating boiler. The device comprises a hollowed-out latticed structure (1), which is mounted on a coal economizer pipeline (2) on the top layer of the whole coal economizer and can cover the whole coal economizer. A pipe clamp is arranged on the lower surface of the latticed structure (1), and the anti-abrasion and explosion-proof device is clamped on an upper exhausting pipe of the coal economizer by means of the pipe clamp. The shape and the size of the anti-abrasion and explosion-proof device can be designed according to different arrangement structures of the coal economizer, so that the anti-abrasion and explosion-proof device can fully cover the coal economizer; and the anti-abrasion and explosion-proof device has the advantages of being more safe and reliable and having obvious anti-abrasion effect.
