Abstract

Sultan Mahmud Hydro Electric Power Station generates 400MW almost everyday to occupy the country needs. Unfortunately, this more than two decades old power station has quite a lot of loss, due to the inefficient cooler system. These coolers that used to cool the turbine parts face a serious heat transfer problem when their piping system are clogged with ferrite formed sludge. This sludge is sourced out from the tailrace. Due to the above reasons, the management has decided to change out open loop cooling water system to closed loop system. Several designs of closed loop system had been recognized, and the system that contains tube and shell heat exchanger was suggested to be the replacement for the existing one. This is because the cost incurred is acceptable and the cost recovery period is not too long. According to the specification, this study focuses to the important parameters, which are; the number of tubes (N), number of transfer unit (NTU) and its effectiveness. Then, another design was suggested, but still maintaining the duty and operating pressure parameters. This suggested idea is to enhance its performance. The varied values of parameters are the mass of fluids and the temperatures. Besides, the modification of the original idea enables the LMTD to be determined. The original LMTD could not be determined since the temperatures of both outlets of the exchangers are same. The scope of work was limited to the theories and calculation of Thermodynamics and Heat Transfer. The overall results of using the theoretical calculation will differ from the using the heat exchanger specialized software.
