| Popis: | The High Hydrogen project seeks to identify the safe limits for use of higher levels of hydrogen in the feedstock to combustion plant utilising heat recovery plant and if necessary develop safety standards to support the findings of the project. This project has investigated the risk potential from use of high hydrogen fuels in conventional turbines or engines with ex thaust ducting leading to heat recovery equipment.The fuel valves in these systems take seconds to close when the system detect a flame failure or in a fault situation so the volume of gas and any diluents passing into the hot ducting prior to full shut down and purge is of interest. Established laboratory test devices have be used to investigate the effects of differing fuel / diluent compositions in the ducting in terms of the potential for ignition, and the strength of the event. This allows for the definition safe levels of hydrogen in the fuel and avoid the potential for a catastrophic event.The first deliverable from this project comprises of a full literature review of data currently available, a fuel matrix identifying the current fuels containing hydrogen and a test plan to fill in the gaps of current knowledge regarding the energetic reaction of these fuel sources.The findings from these tests will be used to develop the tests planned on industrial scale test plant in the next phase of this project. |
