A steam-water separator 7 is installed at the top end of the tank body 6. Symmetrically distributed air injection holes 8, oil filling holes 9, and air vent holes 10 are opened on both sides of the steam-water separator 7. A spherical stop valve 11 is installed in the middle of the front ends of the air injection hole 8, the oil filling hole 9, and the air vent hole 10.
