Title:
METHOD FOR CONTROLLING CONDENSATE SYSTEM, AND CONDENSATE SYSTEM AND SHIP EQUIPPED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2019/163467
Kind Code:
A1
Abstract:
The purpose of the present invention is to appropriately maintain the condensation level inside a condenser even when there is a change in the vacuum state inside the condenser. Provided is a method for controlling a condensate system (1) equipped with: a condenser (10) for condensing steam exhausted from a steam turbine to turn the same into condensate; a gland condenser (12) for heating the condensate from the condenser (10); a tank (14) for storing a portion of the condensate from the gland condenser (12); a condensate pump (16) provided between the condenser (10) and the side of the gland condenser (12) into which the condensate flows; a condensation level control valve (18) provided between the condenser (10) and the side of the gland condenser (12) out of which the condensate is discharged; and a condenser internal pressure detection unit capable of detecting the pressure inside the condenser (10). The method includes a rotational speed switching step for adjusting the minimum rotational speed of the condensate pump (16) in accordance with the pressure inside the condenser (10) obtained by the condenser internal pressure detection unit.
