The invention discloses a method for increasing the energy storage capacity of a steam energy storage tank, which comprises the following steps of: determining the low-pressure gas supply pressure of a steam collecting pocket and a tank body, and recording; the peak pressure of the tank body is determined and recorded; determining a shutdown temperature threshold value of the tank body, and recording the shutdown temperature threshold value; setting a jet flow minimum value of the steam spray pipe; the real-time pressure value in the tank body is recorded in real time; performing numerical judgment on the real-time pressure value, the low-pressure gas supply pressure and the peak pressure to obtain a gas supply scheme; the real-time temperature value of the thermometer is recorded in real time; and the real-time temperature value and a shutdown temperature threshold value are judged, and whether the tank body is shut down or not is judged. High-temperature and high-pressure steam is jetted into softened water
