Title: Operation method for condenser circulating water system
Inventor: KATAKURA KAZUO
IPC: F28B9/04
Filed: 1987-05-14
Abstract: PURPOSE:To eliminate regulation made by a regulating valve and to prevent the occurrence of a regulating valve trouble, by a method wherein, when the amount of circulating water is decreased, the circulation pump for a condenser of other system is stopped, a total amount of circulating water is fed to other system, and circulating water flows through all condensers. CONSTITUTION:Provided the amount of circulating water is limited to 50% of a flow rate prevailing during rated load running, when a circulating water pump 4b of a condenser 1b of other system is stopped, a part of water flowing out from a condenser 1a is fed through a communicating pipe 6 to the condenser 1b resulting from throttling of the opening of a water chamber outlet valve 11a, and is returned through a communicating pipe 8 to a circulating water pipe 5a again and is fed to a discharge tank resulting from full closing of a water chamber outlet valve 11b. Thus, even when the circulation pump 4b is stopped, the amount of circulating water is kept at 50% through the working of a single pump 4a. This constitution eliminates wide regulation of a flow rate by means of the regulating valves 11a and 11b, and enables prevention of the occurrence of a damage trouble on the regulating valve.
