A combined Gasification, methanation and power island steam turbine system. The system includes a gasification portion, the methanation portion and a steam turbine portion. The Gasification portion includes the new heat recovery design and associated controls for obtaining a desired steam to dry gas ration of 1.1-2.2. The methanation portion includes first, second and third methanation reactors and associated heat recovery integrated with a high-pressure, low-pressure superheater, and HP economizers. The power Island steam turbine includes a High pressure, Intermediate pressure, low-pressure steam turbine having an input coupled to an output of the superheaters in Methanation process.

Methods and systems of operating an integrated gasification combined cycle system are provided. The method includes coupling a non-fuel fluid conduit to a fuel conduit, warming a flow of non-fuel fluid, and channeling the warmed non-fuel fluid through the fuel conduit such that heat from the warmed non-fuel fluid heats the fuel conduit to a predetermined temperature.
