Flue gascondensate heat exchanger (GCH) system in ultra supercritical coalfired unit can effectively use the boiler flue gas waste heat to heat the steam condensation water, improving the unit’s economy in operation. Combining GCH transformation project of a power plant, the layout characteristics of GCH system were introduced, which were two level arrangement and multiple modules per level. According to the GCH system layout, the GCH outlet gas temperature control strategy and the control function of ensuring GCH pathway normal were designed. The GCH system commissioning and operation were described and the economic benefit was evaluated. Data shows, after GCH system operation. So energysaving and emission reduction were successfully achieved and the expected goal was realized.
