Wherein, described air duct comprises air inlet, air outlet, valve, at least two air channels, and air inlet, air outlet communicate with the air channel, and valve is installed on the air channel, near the air inlet.

Wherein, described electric central warm air furnace comprises stove case, several heating wire, electrode, and heating wire is contained in the stove case, and electrode is connected on the heating wire two ends.

Wherein, described wind-driven generator comprises support, generator, wind wheel, and rotor shaft, generator are fixed on the support, and wind wheel is connected with generator by rotor shaft.

Wherein, the hot stove of described baked wheaten cake coal is provided with hot-air channel, and this hot-air channel is between the inner bag and exterior wall of burning the hot stove of coal.

Owing to taked above technical scheme, advantage of the present utility model is:

1 owing to increased hot-flow flue in burning the hot stove of coal, the hot blast temperature of therefore sending into drying tower is improved, and has reduced drying time, has saved burning coal amount.

2 when the hot stove of baked wheaten cake coal send hot blast, and the utility model adopts wind-power electricity generation to provide electric energy for electric central warm air furnace, has therefore reduced the consumption of the electric energy of electric central warm air furnace.

3 owing to the time decreased of burning coal, to the pollution minimizing of environment.
