| 20110315096 | Gasifier Hybrid combined cycle power plant - The invention provides a system and method for the efficient, clean and simultaneous conversion of multiple fuels, including but not limited to waste derived gas, liquid and solid phase fuels, to electrical energy. The present invention used a closely coupled combined thermal cycle system based on an air fed gasifier and an internal combustion engine. Steam generated by exhaust heat from an internal combustion engine and from the combustion of syngas produced by the gasifier is used to power an admission steam turbine in an efficient system in which components such as water treatment, heat recovery, and other components are common to gasifier and the internal combustion engine. The invention offers several advantages over other combined cycle power plants employing gasifiers. These advantages include fuel flexibility, efficient operation at generating capacities in the 30 to 120 MW range, commonality of components, and the capability to provide both base load and demand load power from a variety of waste derived fuels. | 12-29-2011 |
