Coal-fired open-cycle liquid-metal magnetohydrodynamic topping cycle for retrofit of steam power plants. [Two-phase working fluid composed of coal combustion products and liquid copper]
The application of the new, coal-fired open-cycle liquid-metal MHD (OC-LMMHD) energy-conversion system to the retrofit of an existing, oil- or gas-fired conventional steam power plant is evaluated. The criteria used to evaluate the retrofit are the new plant efficiency and the cost benefit relative to other options, i.e., continuing to burn oil, a conventional retrofit to burn coal (if possible), and an over-the-fence gasifier for boilers that cannot burn coal directly. The OC-LMMHD cycle and the existing steam plant used in the study are discussed, and a detailed description of the retrofit plant is presented. The latter includes plant drawings, description of the coupling of the OC-LMMHD topping cycle and the steam boiler, drawings and descriptions of the major components in the retrofit plant, and costs. The unique capability of the OC-LMMHD cycle to control the pollutants normally associated with burning coal is discussed. The net plant output powers and efficiencies are calculated, with allowances for the required auxiliary powers and component inefficiencies, and a plant lifetime economic analysis performed by an architect/engineer. The efficiency and cost results are compared with the values for the other options.
