Ben Chorpening of the Office of Research and Development at the Department of Energy’s National Energy Technology Laboratory inspects the combustion control and diagnostics sensor (CCADS) installation in NETL’s SimVal rig section. NETL and Woodward Industrial Controls are developing CCADS, which has already been demonstrated as a useful sensor for use in situ monitoring of natural gas combustion, including detection of important combustion events such as flashback and lean blowoff. Real-time in situ monitoring of flashback is important for the development of control strategies for use of hydrogen augmented fuel in state-of-the-art combustion systems, and for the development of advanced hydrogen combustion systems. Since CCADS is a flame ionization sensor technique, the low ion concentration produced in pure hydrogen combustion raises concerns of whether CCADS can be used to monitor flashback in hydrogen augmented combustion. Testing at NETL demonstrates flashback detection with fuel compositions up to 80% hydrogen (by volume) mixed with natural gas. The testing in NETL’s Simulation Validation (SimVal) combustor offers full optical access to pressurized combustion, which provides insight into the effect of flame location on the CCADS signals. This work is being conducted under a CRADA with Woodward Industrial Controls. Funding for this work was provided by DOE's Gas Turbine Program.
