Using Temporary Cooling Systems

摘要

Many plants rely on river or lake water for their condenser and equipment cooling and must ensure that discharge water stays within certain temperature limits. Problems with reduced river flows and lake levels and increased intake temperatures mean that plants are having to reduce load to meet discharge temperature requirements. The alternative is to use temporary cooling towers. Aggreko LLC operated five thermal discharge projects at power plants during the summer of 2008. Discharge water from the plant is passed through the cooling towers for cooling and is then released into the river or lake. With modern data recording systems, it is relatively easy to document system performance, Btu removal and system run time, which helps to verify cost-benefit models as well as satisfy regulating bodies or inspectors. A variety of cooling water manufacturers and rental companies can provide temporary systems. Choices range from companies with full engineering staffs and project managers to companies that simply provide equipment.
