Mountain Fuel Resources, Inc., a subsidiary of Mountain Fuel Supply Company, Salt Lake City, Utah, is under contract with the US Department of Energy for a program to design, construct and operate a high-rate, entrained flow coal gasification process development unit (PDU). The design of the coal gasification PDU is based on earlier DOE-supported work at the Eyring Research Institute, Provo, Utah. The PDU is to be located adjacent to a brick plant operated by Interstate Brick Company in West Jordan, Utah. Because of the developmental nature of the program, the PDU will contain only those components and features necessary to develop the gasifier and to operate it safely. Radiant heat exchanger, steam superheater, and transition pipe design work by Deutsche Babcock was started in mid-October and the first set of the drawings were delivered to MFR and FBDU in early December. The radiant heat exchanger design was revised and finalized. The gasifier injector head and reaction chamber design was completed. Purchase orders were issued for approximately 80 percent of the major equipment. Specifications were being prepared for the remaining equipment, i.e., coal conveyor, radiant heat exchanger and steam superheater and the transition pipe in-between. The site preparation work was started in late September and was completed in October. Most of the foundations, except the coal handling building and liquid oxygen and nitrogen area, were completed as of the end of December.
