Overview

Gas turbine development is a key area if higher efficiencies are to be achieved by both gasification and combustion technologies.  However, pilot-scale test facilities are normally in the hands of private companies, and their results are usually generated for commercially driven programs and not available for public use.

Applications

This facility allows extensive material testing for turbine related activities, and builds on Cranfield’s international reputation for materials testing in the energy field with partnerships across the UK and the USA as well as the rest of the world.  It is currently being upgraded to operate at temperatures of 1500°C. 

System Description

This facility is equipped with downstream probes for deposition/corrosion (globally unique) and simulates gas environments at temperatures up to 1400°C.  It allows the testing of different gas and liquid fuels, along with solid contaminants to simulate their effect on a gas turbine (GT) and allow corrosion and deposition studies to be carried out over hundreds of hours or more.  This unit allows the use of up to 40 air-cooled deposition probes which are individually controlled to understand the failure mechanisms.

Integrated components

This equipment has extensive gas mixing and handling systems to allow various possible syngas compositions to be examined.  It can be used to simulate gas turbine exhaust gas recycle, and can also be used with H2-rich syngas or operated in an oxy-fuel mode.  Also, this unit is equipped with SO2/HCl injection and trace element injection via liquid spraying to atomise the elements before burning.

Analytical Capability

This unit, like all of Cranfield’s test rigs, comes extensively equipped with sampling/feed ports and offers the potential to use advanced techniques like 3D laser diagnostics and thermal imaging to provide data which can be used in state-of-the-art CFC and process modelling for full-scale facilities.
