OSTI ID:678976
This site-specific study describes the technical and economic feasibility of a biomass gasification combined cycle producing heat and power for a typical Finish pulp and paper mill. The aim is to replace an old bark boiler by an IGCC (Integrated Gasification Combined Cycle) to enhance the economy and environmental performance of the power plant. The IGCC feasibility study is conducted for a pulp and paper industrial plant because of its suitable infrastructure for IGCC and a large amount of wood waste available at the site. For comparison, the feasibility of an IGCC integrated to a pulp mill is also assessed. The operation and design of the IGCC concept is based on a 20 MW(e) gas turbine (MW151). The heat of gas turbine exhaust gas is utilized in a HRSG (Heat Recovery Steam Generator) of two pressure levels to generate steam for the pulp and paper mill and the steam turbine. The IGCC power plant operates in condensing mode. The techno-economic assessment of the biomass IGCC integrated to a pulp and paper mill or a pulp mill indicated that the IGCC will be competitive compared to the conventional bark boiler steam cycle. The IGCC integrated to a pulp and paper mill was slightly more economical than the IGCC pulp mill integration.
