A
hydrogen-fuelled kiln test rig is helping brick and ceramics manufacturers to support the a kiln and furnace manufacturer
specialist Bürkert to manage the precise and reliable control of hydrogen. The result for end users is increased production quality enabling a more sustainable process. used primarily in the production process of that it can scale its operation with a fuel mix of 20 percent hydrogen or more. The test kiln has been developed to support businesses making the transition to the increased use of hydrogen. considering plans to blend the supply of gas in the network with 20 percent hydrogen. For and concentration of gas impacts the curing process. The new kiln design is enabling manufacturers to test their production processes with a hydrogen blend and monitor advance of a government switch-over. The new test kiln can currently control the though there is a plan for the potential use of 100 percent concentration. This scalability is enabling brick and ceramic producers to production lines.
CONTROLLING THE BLEND
A key challenge in the development of the new kiln has been the integration and control of the gas blend. High accuracy is required to ensure exacting regulation of the hydrogen operational conditions. Control reliability also has to be repeatable for manufacturing processes lasting up to 24 hours or more. A programmable logic controller (PLC) including temperature and pressure sensors. specialist Bürkert. In order to ensure precise
a measuring accuracy deviation as low as ±0.3 percent and repeatability down to just ±0.1 percent. This precision is enabling customers to test exacting hydrogen concentrations to optimise their processes.
PLUG-AND-PLAY CONNECTIVITY
enabling seamless communication between communications in integration of the hydrogen controller was vital.
As the hydrogen test kiln is regularly used they each have their own control parameters. make fast changes.
Since the Bürkert communications gateway converts the signal to the desired cost of additional licences required to extend integration to the PLC using same-vendor devices. This is particularly advantageous to enable scaling up of the technology in the future for use on industrial-sized kilns and furnaces. the Bürkert communications gateway also

enables remote connectivity and management of the production process.
ENABLING HYDROGEN TRANSITION The brick and ceramics manufacturers who have so far tested hydrogen use at 20 percent compared to using 100 percent natural gas. The next stage is the widespread testing of concentrations up to 40 percent and beyond. hydrogen could eventually see the price of this gas fall to parity or even lower than current gas
