Biomass Fuelled Indirect Fired Micro Turbine

Abstract:

This document is a report for the project titled 'Biomass Fuelled Indirect Fired Micro Turbine'. <p>The aim of this project was to further develop micro turbine indirect firing and to develop this into a biomass generator, building on the success of the previous project. The system was redesigned and rebuilt using the experience gained and the recommendations reported in our last project. The efficiency, maintenance and safety of the system was improved through this development project.</p> <p>The Specific aims were: <bl> <li>To achieve 4000hrs run time</li> <li>To establish a start procedure</li> <li>To develop safe and predictable operation without the need for supervision</li> <li>To prove heat exchanger concept</li> <li>To achieve full recuperated operation</li> <li>To achieve high temperature combustion with low emissions</li> <li>To establish costs and technical basis for future development</li> <li>To provide a demonstration of working biomass renewable power generation</li></bl></p> <p>The main achievements of these projects are: <bl> <li>Start procedure established and well proven with over 100 successful starts</li> <li>4680 hours turbine operation so far</li> <li>Safe and predictable operation without supervision</li> <li>Heat exchanger concept proven</li> <li>Fully recuperated operation achieved</li> <li>High temperature combustion achieved with ultra low emissions</li> <li>The Biomass Generator has demonstrated that it is possible to produce 20-30kW of renewable electricity in a stable, reliable manner</li> <li>Cost and technical basis for future development established</li> <li>Demonstration of working biomass renewable power generation</li></bl> The concept is now well proven the next logical step is to improve the system and build on our success.</p> This report is divided into the following sections: <ol> <li>Introduction</li> <li>Re-evaluation and Design</li> <li>Initial Testing</li> <li>Long Term Testing</li> <li>Results and Discussion</li> <li>Conclusions</li> <li>Recommendations</li> <li>Acknowledgements</li> </ol>
