Safety of Combined Cycle Gas Turbine and Gas Engine Systems Operating on Hydrogen Rich Syngas and Biogas

摘要

The UK Energy Technologies Institute (ETI) is supporting a multi-partner project to investigate the safe operation of combined cycle power generating systems running on syngas and biogas. The project, led by the UK Health and Safety Laboratory (HSL) looks particularly at hazardous situations that may result in an explosive fuel mixture entering the exhaust and Heat Recovery Steam Generator (HRSG), and igniting. The findings from this work using a large scale experimental facility on the 550 acre HSL site near Buxton, Derbyshire, UK are discussed. The facility simulates the conditions in a HRSG, utilising the exhaust gas from a Rolls-Royce Viper jet-engine to reproduce the temperature and flow conditions. The effects of turbulence generated by the HRSG heat exchangers are reported. Results from the test programme are presented which demonstrate deflagration to detonation transition under certain conditions.
