Abstract

PURPOSE: To remove water scale from the inner surface of a heat absorption tube and to improve the cooling efficiency by reversing the flowing direction of a cooling water by a selectable switching of valves, with a connection path provided between a water supplying and condensate pipes, and a bypass provided in a main and auxiliary water supplying pumps.
CONSTITUTION: Communication valves 14 and 16, bypass pipe valve 10 and a valve for an auxiliary pump are closed during water supplying operation of main pump while a condensate pipe valve 13, main pump valve 9, bypass vlave 12, and a water supplying pipe valve 15 are opened to circulate the cooling water. The valves 14, 16, 10 and 11 are opened during water supplying by the auxiliary pump 8 and the valve 13, 15, 9 and 12 are closed to promote the circulation and the scale is removed because of the inversed flow in a heat absorption tube 19. The attaching of the scale can be prevented to imorove the cooling efficiency by alternating operation of the pumps 7 and 8.
