Task 5.1 Instabilities in boilers with complex thermoacoustic properties

The ESR assigned this task will build a laboratory test rig that mimics the combustion chamber of a particular boiler type. The combustion chamber contains a unique burner deck and several rows of finned heat exchanger tubes. The test rig will include a mixing facility so that the hydrogen content can be varied. Other variable parameters are the temperature of the cooling water, and the properties (geometry, spacing, etc.) of the fins. The ESR will take a combined experimental approach (measuring transfer functions using hot wire anemometry and chemiluminescence, and transfer matrices with multiple microphone technique) and numerical approach (using Comsol) to develop a network model for this test rig. This will then be used to perform parameter studies to explore which design modification will guarantee stability in a wide range of operating conditions.
