A method for improving effectiveness of a steam generator system includes providing a steam generator system including a steam generator vessel, an air supply system and an air preheater. The air supply system is in communication with the steam generator vessel through the air preheater and the steam generator vessel is in communication with the air preheater. The air supply system provides a first amount of air to the air preheater. At least a portion of the first amount of air is provided to the steam generator vessel. A flue gas mixture is discharged from the steam generator vessel. At least a portion of the flue gas mixture flows into the air preheater. SO.sub.3 in the flue gas mixture is mitigated before the flue gas mixture enters the air preheater.

A power generation system in which the combustion heat of hydrocarbon gas is used to heat the steam for power generation; at the same time, the exhaust heat thereof is used to dry and thy-distill low rank coal. The power generation system includes: a dry distillation step for dry-distilling low rank coal of high moisture content; a cooling step for cooling the fixed carbon obtained in the dry distillation step; a combustion step in which hydrocarbon gas obtained in the dry distillation step is used as the main fuel; and a power generation step in which there are provided a power generator moving a steam turbine by main steam generated in the combustion step and a condenser.
