Beschreibung
Zusammenfassung:	The invention relates to a device for improving inlet air temperature of an air pre-heater in electricity generation. The device uses high-pressure hot air to directly heat low-pressure cold air which enters the air pre-heater from the outlet of an axial-flow fan; the device comprises a hot air circulating pipe, and the hot air circulating pipe is communicated with a primary hot air outlet of the air pre-heater and the outlet of the axial-flow fan. The device for improving the inlet air temperature of the air pre-heater in the electricity generation has beneficial effects that the investment cost is reduced; the running cost is reduced; environment pollution waste water emission is avoided.
