Abstract: In this paper, there are two High Pressure Heaters (HPH) were out of service due to lake of maintenance. According to this issue, the unit efficiency decreased which consumed more fuel to compensate the temperature drop. During water circulating in a condensate water system there are heat waste, temperature drop, low performance and poor quantity of heat transfer which will cause an insufficient efficiency due to High Pressure Heaters (HPH) are not working properly. To remedy this issue, we study and focused on how efficiency can be improved when high pressure heaters in service and compare the results between the two situations in and out of service by calculate different parameters; TGHR, TNHR, Boiler efficiency and NUHR. Fuel cost effectiveness studied in this paper at maximum heat rate difference 11.8 kJ/ kWh.
