摘要

More than twenty integrated gasification combined cycle (IGCC) power stations have already been built since 1990 or are under construction or design worldwide with power output between 40 and 550 MW. This type of plant stands out due to its excellent performance in terms of efficiency and environmental impact and offers a very promising power generation option which can be used with a large variety of so-called dirty fuels, i.e. solid or liquid feedstocks such as refinery residues, coal and biomass. This paper reports the progress achieved to date in the two large-scale European integrated hard-coal-gasification combined-cycle power plants in the Netherlands and Spain as well as the asphalt-based IGCC station in Sicily, which are all equipped with Siemens gas turbines. When considering oil and refinery trends toward heavier crudes and residues with high sulfur and heavy metal content, it is of particular interest that gasification and gas cleaning act as an extremely effective filter for all the contaminants harmful to gas turbine blading and the environment. The paper gives an estimate of the quantity of residues which can be expected for power generation. Recent study results including a cost estimate based on Western European conditions, which suggest that the target purchase price of US$ 1,100 per kW installed capacity is likely to be verified for advanced next generation coal-based IGCC stations in the near future, are also discussed. The commercial breakthrough, however, is expected to be supported first by refinery-related applications.
