Steam generation tank for power station

The invention discloses a steam generation tank for a power station. The steam generation tank comprises a tank body and a solar outer heat pipe. A liquid inlet pipe is formed in the side wall of the tank body, two gas outlet pipes which are symmetrical are formed in the side wall of the top end of the tank body, nozzles are rotationally arranged on the inner walls of the two gas outlet pipes, a plurality of spiral protrusions are installed on the inner walls of the nozzles, a diversion plate is fixed to the top end of the tank body, the axis of each gas outlet pipe is right opposite to the bend outer conical surface, and a solar inner heat pipe is fixed into the solar outer heat pipe through a flange plate. According to the steam generation tank, after steam is discharged into the tank body, the diversion plate with the middle portion downwards protruding to form an inverted cone is arranged on the top of the tank body, the inverted conical outer conical surface bends inwards along the center line of the inverted cone, that is, the longitudinal cross section of the inverted cone is in an inverted ridge shape, the diversion plate provides curve path guiding for the movement of steam, discharging of the steam is accelerated, and meanwhile the situation that steam is accumulated on the top of the tank body, consequently, part of steam is fused and then freely descends is avoided.
