WASTE TO ENERGY
PROTECTING NEW INDUSTRIES
Here Dräger tells us how the company provided fl ame and gas detection for a biowaste to hydrogen plant
M
any of the contributors to International Power Engineer are developing products for the biowaste
to fuel industry, and Flame and gas specialist Drager is no exception. The company recently reported a case study regarding a hydrogen- from-biowaste production facility based in the Midlands that utilised its fl ame and gas detection. The company was keen to ascertain if the planned gas and fl ame monitoring system which covered the storage tank and compressor area of the site was both fi t for purpose and in line with the appropriate standards and regulations.
STORAGE TANKS A total of four storage tanks and eight compressors at the site process the hydrogen at 300 times standard atmospheric pressure until it is piped onto lorries in the nearby loading bays for onward transportation. Financial margins at the production
facility were extremely tight, creating signifi cant pressure on costs, but the project engineer wanted peace of

mind that the planned fi re and gas monitoring and detection provision was adequate and suitable. Furthermore, the site owners
wanted to ensure that should the worst happen, in the form of a fi re or gas leak, they could be certain that they had taken every precaution to ensure that their health and safety provision was adequate and appropriate.
MAPPING AUDIT Dräger was asked to conduct a fi re and gas mapping audit to consider the planned monitoring and detection coverage across the site, as well as identify any ‘blind spots’, and advise on both the appropriateness of the current position and set up of the system’s devices and whether any further coverage was needed in order to meet coverage requirements. Using a 3D drawn model of the
site using mapping software, the coverage visibility of each fl ame and gas detection device could be superimposed, with the ability to move the direction of each detector in the modelling software to determine not
only the optimum location for each device to achieve best coverage, but also the best directional positioning. The eXida certifi ed software then
produced a clear visual diagram with green areas showing the site locations that were adequately covered by fl ame and gas monitoring, and any blind spots highlighted in red. The project manager proposed
six fl ame detectors, however the fi re and gas mapping process not only confi rmed that the fl ame detection coverage could be achieved with fi ve fl ame detectors and delivering coverage of 99% – a coverage level that the customer felt was acceptable and would provide the required coverage. The fi re and gas mapping process determined one fl ame detector was surplus to requirements and could be removed without any adverse impact on site safety, saving the customer several thousands of pounds.
