To comply the regulation, the sulfur dioxide (SO 2 ) concentration should be reduced to designated standard of emission which was stated in the regulation. It causes many coal fired power plant (CFPP) need to procure a new or upgrade their desulfurization equipment. In this study the desulfurization method focused on the usage of Limestone forced oxidation (LSFO). The study is based on subcritical 300 MW CFPP and the specification of coal for the calculation was taken from coal properties of Palu 3 CFPP. There are two cases and two configurations in this study. The first case is flue gas oxygen content of 3.5% and the second is 7%. Then in the configuration of with or without gas-gas heater (GGH). The oxygen content condition in the flue gas have an influence to the presence of GGH within LSFO desulfurizer system. The lower of oxygen content in the flue gas then increase the tendency to use GGH.
