A system includes a syngas cooler configured to cool a syngas. The syngas cooler includes a first syngas cooler section configured to cool the syngas and a second syngas cooler section configured to cool the syngas and generate a first superheated steam with an enthalpy of less than approximately 3800 kJ/kg.

System for cooling syngas

In one embodiment, a component for a power generation system includes an interior volume for containing steam condensate or gas turbine exhaust gas. A phase change material is disposed around an external surface of the combined cycle power generation system component.

Methods and apparatus for fast starting and loading a combined cycle power system are described. In one example embodiment, the method includes loading the gas turbine at up to it's maximum rate, and loading the steam turbine at its maximum rate with excess steam bypassed to the condenser while maintaining the temperature of steam supplied to the steam turbine at a substantially constant temperature from initial steam admission into the steam turbine until all steam generated by the heat recovery steam generator is being admitted to the steam turbine while the gas turbine operates at up to maximum load.
