The present invention relates to a power driven automatic boiler.

Conventional boilers inject coal on the semi-open casting plate and burn it by natural or forced blowing, so the plate is heated and low in durability, and coal is burned by forced blowing, so it is incompletely burned during the initial combustion. Gas is generated. In addition, since coal is simply supplied and combusted, the position of the height is not constant and ashes are attached to the fire plate, which causes inconvenience of frequent cleaning because the outside air is blocked.
