Abstract
The heat exchanger with condensation is widely used as a condenser, a heater in the process industry and a turbine condenser in the power system. Many reports are published on the analytical and experimental investigations of the transient characteristics of heat exchangers with condensation. However, few attempts are made to study the dynamic behaviors with a steam flow rate change.
In this report, there are investigations on the analytical and experimental approach to describe the performance of a heat exchanger with condensation used as a turbine condenser in a steam power system. The heat exchanger in the experimental use is a horizontal tubular type condenser. The condensate does not come in contract with the tubes and is kept in a constant low level under tubes.
The author, through analytical studies, showed the expression to infer some transient characteristics and through experimental studies clarified that the pressure response to a steam flow rate change may be represented by the transient characteristics of a simple concentrated parameter system.
