The invention discloses a temperature-control variable-pressure heat accumulator control system, which mainly comprises a heat accumulator. The heat accumulator is respectively communicated with a steam inlet pipe and a steam outlet pipe. A short loop pipe is arranged between the steam inlet pipe and the steam outlet pipe and communicates the steam inlet pipe with the steam outlet pipe. An inlet check valve is arranged on the steam inlet pipe between the short loop pipe and the heat accumulator. A temperature-control regulating valve and a short loop check valve are arranged on the short loop pipe. A steam pressure sensor and a water temperature sensor are arranged on the heat accumulator, wherein the steam pressure sensor is used for measuring saturated steam pressure and the water temperature sensor is used for measuring water temperature. The sensing signal of the steam pressure sensor and the sensing signal of the water temperature sensor are input to a controller. The output end of the controller is connected with the execution signal of the temperature-control regulating valve. A control method is characterized in that the temperature-control regulating valve is controlled through the deviation of the steam temperature and the water temperature to enable the inlet steam into two loops, wherein one loop is used for supplying steam and the other loop is used for accumulating heat and releasing heat if required. The invention has the advantages that the steam volume and the steam pressure are ensured to be stable and thereby the output of a waste heat recovery system is maintained to be maximum.
