Tampella, Ltd., in cooperation with the Institute of Gas Technology (IGT), is developing the gasification technology for U-GAS{reg sign} to produce electricity from coal using the integrated gasification combined-cycle (IGCC). The concept of IGCC is to join the clean burning gasification island with a more efficient gas and stream turbine island to produce electric power with minimal environmental impact. IGT has developed the U-GAS process to produce a low- or medium-Btu gas from different types of coal feedstocks. The process uses a combination of fluidized=bed gasification and ash agglomeration in a single-stage reactor. A 30-tons/day-capacity pilot plant located in Chicago has been used to develop the process. Feedstocks ranging from relatively unreactive metallurgical coke to highly reactive peat have been gasified successfully in the this pilot plant, indicating its ability to handle a feedstock with widely varying properties. A new 10 megawatt pilot plant has been designed and is under construction in Tampere, Finland, as the first step toward the commercialization of this technology. Tampella is planning to design and deliver a commercial-scale IGCC demonstration plant by 1994. 7 refs., 5 figs.
