As advanced processes are used commercially for converting coal to other forms of energy, reliable valves will be required for operating in lockhopper service at pressures to 1200 psig (8.3 MPa) and temperatures to 1600°F (870°C). The Department of Energy’s Lockhopper Valve Testing and Development Project, being conducted at the Morgantown Energy Technology Center (METC), is cooperating with lockhopper valve manufacturers and users to improve the state-of-the-art capability of commercially available lockhopper valves. The test facilities and valve testing program currently being made available to valve manufacturers at METC are described. The performance of test valves currently in the program is summarized and design considerations for solids lockhopper service are discussed.
