The invention discloses a system for improving the drying output of a direct-fired pulverizing system, which is characterized in that a smoke exhaust port of a boiler body steering chamber is communicated with an inlet of a high-temperature electric dust remover, an outlet of a denitration device is communicated with the inlet of the high-temperature electric dust remover, and an outlet of the electric dust remover is communicated with an inlet of a high-temperature primary fan; an outlet of the high-temperature electric dust remover is communicated with an inlet of a high-temperature primary fan, an outlet of the high-temperature primary fan is communicated with an inlet of a coal mill hot air door, the outlet of the primary fan is divided into two paths, one path is communicated with the inlet of the coal mill hot air door through the air side of an air preheater, and the other path is communicated with the outlet of the coal mill hot air door. The outlet of the coal bunker is communicated with the inlet of the coal mill, the outlet of the coal mill is communicated with the inlet of the boiler body, the temperature of hot primary air can be increased, and meanwhile the system has the advantages of being low in smoke exhaust temperature, high in boiler efficiency and high in safety.
