The invention discloses a boiler powered by a wind-driven generator. The boiler comprises a wind power generation system, a solid heat accumulating type boiler body, a heat exchange device and a heat consumer. The power generation system supplies power for the solid heat accumulating type boiler body. The solid heat accumulating type boiler body is connected with the heat exchange device into a circulation loop. The solid heat accumulating type boiler body supplies heat to the heat consumer directly, a double-stator motor capable of working under three manners is adopted, and a photovoltaic emergency power supply supplies power to a boiler system. The power cost of a heat supply system is lowered, energy is saved, pollution to the environment is avoided, and the reliability of heat supply is improved.
