Biomass turbine for co-generation (BTC) - Assessment study and pilot project


The objective is to demonstrate the possibilities and the special benefits of firing C4-biomass in gas turbines for decentralized generation of electricity and heat.

This research programme comprises the development of a prototype generation plant for direct firing of C4-biomass in gas turbines and the development of a fast rotating generator to be driven by the turbine for a decentralized production of electricity and heat.

The programme is separated into: 1) an assessment study, and, 2) a pilot project.

1) The assessment study will be made to point out the technical feasibility and the economic perspectives of a 400 - 500 kWe co-generation plant fired with biomass. Also future R&D activities will be defined.

2) The pilot project consists of three phases, only the first phase will be carried out in this programme. Phase 2 and 3, which contains the construction of a pilot and a demonstration plant, may be carried out in a future programme.

The main tasks in Phase 1 are:

- evaluation of the market for decentralized electricity production;
- study on co-generation;
- study on biomass production and the processing into powder;
- chemical and physical analysis of C4-plants powder;
- investigation of a combustion system for firing biomass powder;
- evaluation of the additional problems by ash particles;
- investigation of a recuperator and a flue gas filter;
- choice of an electrical generator and study on its connection to the grid.

Experimental testing will be done to investigate the behaviour of biomass powder in the combustion chamber and to measure the emissions of gaseous and solid components in the exhaust gas.
