Dry Coal Handling and Feeding Test Facility Feasibility Study

摘要

Research and development efforts on coal conversion have resulted in a number of technically feasible processes to synthesize gas and oil from coal. To justify commercialization, these processes must be proved in demonstration plants using reliable equipment. Fossil Energy (DOE-FE) has a strong interest in improving the performance and reliability of critical components needed in proposed coal conversion demonstration plants. Consideration has been given to the possibility of performance and endurance testing these components in dedicated facilities. Such testing would give maximum assurance that proven components are available for use in demonstration plants. Among these critical components are various type of coal handling equipment, including dry coal feeders for gasifiers operating at high pressures. Oak Ridge National Laboratory (ORNL) was asked by DOE-FE, Fossil Fuel Processing, to perform an advanced planning study on a non-site-specific basis for the scoping of the conceptual design of a pilot-scale coal handling and feeding test facility. In such a facility, coal feeders and other handling equipment would be exposed to actual or simulated conditions in performance and endurance tests. Arrangement, physical characteristics, and costs for such a facility were investigated. Full consideration could not be given to general support facilities, utilities, general process materials, storage and supply, or effluent treatment, as these factors are strongly site dependent. Preliminary engineering concepts were developed. Recommendations are included. (ERA citation 04:045875)
