Abstract

The overall objective of the project is to develop sustainable and economic systems for ash management of biomass/waste gasification and the gas cleaning process. The primary objective is to reduce ash volume and improve ash quality.

The improvement of ash quality enhances the potential for the utilisation/recycling of ashes as a raw material for other processes. One of the key factors limiting further utilisation of gasification fly ash is the carbon content. Unreacted carbon has a negative impact not only on quality but also on the carbon conversion of the gasification process.

An essential part of the ash quality improvement and ash volume reduction is the improvement of carbon conversion. An increase in carbon conversion results in higher conversion efficiency and this has a direct positive influence on power production capability.

Consortium

VTT Processes coordinates the project which consists of seven partners. VTT Processes, Foster Wheeler Energia Oy (FWEOY), Energy Research Centre of the Netherlands (ECN), Asociación de Investigación y Cooperación Industrial de Andalucía (AICIA), Pohjolan Voima Oy (PVO) and EMC Environment Engineering Limited are the principal contractors and Essent Energie Productie b.v. (EEP) is the assistant contractor. The project group has extensive experience and knowledge related to R&D and large-scale gasification, commercial-scale power production and gasifier manufacturing. This project enables the effective utilisation of this experience to achieve significant improvements in the overall feasibility of large-scale biomass and waste-derived fuel gasification.
