The invention relates to the field of thermal power generating unit heating modification and discloses a double-extraction adjustable heating system of the thermal power generating unit. By modifying a turbine heating pipeline, a first by-pass pipeline and a second by-pass pipeline connected with a high-pressure cylinder and a medium-pressure cylinder in parallel are arranged on a steam supplying pipeline of the high-pressure cylinder and the medium-pressure cylinder respectively. Each by-pass pipeline is connected with an adjusting gate, a spray type desuperheater and a pressure matcher, and the pressure matcher of the first by-pass pipeline injects exhaust steam of the high-pressure cylinder to achieve high-pressure steam supplying. The second by-pass pipeline injects low-pressure extraction steam of the medium-pressure cylinder to achieve medium-pressure steam supplying. Simultaneously, the opening degree of a middle adjusting gate is adjustable, and the opening degree of the middle adjusting gate is adjusted according to exhaust steam pressure change of the high-pressure cylinder and reheating steam pressure change caused by load change. Therefore, a steam supplying pressure requirement towards the outside is met, qualified steam supplying pressure is guaranteed, a purpose of double-extraction, adjustability and heating of steam of the unit for high-pressure industries and medium-pressure industries is achieved, modification cost of a unit body is saved, and an effect of reducing energy and emission is achieved.
