Abstract:
The tasks of this research project are to investigate the potentialefficiency improvements and the potential reduction in cost for manufacturing
and erection (plant delivery price) of a Puertollano type IGCC power plant
and to assess the economy and environmental impact. Also, the technical
feasibility and profitability of co-gasification of biomass in oxygen-blown
entrained-flow IGCC plants are to be studied. Besides, the Universities of
Essen and Ulster and the Netherlands Energy Research Foundation (ECN), the
companies Krupp Uhde and Siemens are participating in this project. They have
manufactured and supplied major components for the Puertollano IGCC power
station. Siemens has also delivered the combined gas and steam turbine plant
for the Buggenum IGCC power station in the Netherlands. They put their
knowledge gathered from the engineering of these plants into this project and
will furthermore use the design principles and know-how elaborated in this
JOULE project for follow-up IGCC power plants. Co-gasification of biomass in
IGCC coal power plants reduces CO2 emission. The use of this fuel is a
further step towards a sustainable energy supply system. ECN conducts
supporting lab-scale experiments and studies different variants of highly and
low integrated IGCC systems. The University of Ulster carries out detailed
techno-economic analyses based on mass and energy balances under the
assumption of equal market, ambient and technical boundary conditions. Hence,
costs of power plants and of electricity generating are calculated without
first-of-its-kind costs at the same data base and are, therefore, comparable
to the various power plant concepts. The University of Essen acts as the
contract coordinator and contributes to process thermodynamics and
optimisation of the IGCC power plants and investigates efficiency improvement
potentials and cost effectiveness of improvement measures. 12 refs.
