Straw gasification for co-combustion in large CHP plants (STRAWGAS). - Final publishable report. - May 2001

Funded under: FP5-EESD


Final publishable report of project ERK5-CT-1999-0004.

This document covers the process validation of the gasification and gas cleaning tests that were carried out in 2000 and the design study of a 100 MWth gasifier. Furthermore, gasification of 100% straw and of a fuel mix of straw and wood is covered in the process validation and design study.

The experimental research consisted of 3 main tasks:

- The capability of the developed feeding system to feed loose straw into the gasifier;
- The optimal process conditions and additives for gasifying loose straw;
- The capability of the selected gas cleaning system to make the gas suitable for co-combustion in large CHP-plants;

In the design study a full-scale straw gasification plant of 100 MWth and the integration with an existing large CHP plant was investigated. The practical solutions of all unit operations were developed. The budget for a complete plant was calculated and consequently the overall project economy was assessed.
