Experimental Measurements For Pyrolysis Model Validation - Anaerobic Gasification Of PMMA Under External Thermal Radiation

A set of 10 anaerobic gasification experiments was conducted on the poly(methyl methacrylate), PMMA, made available to participants in the MaCFP-2 Workshop. In each test, samples (i.e., PMMA discs of approximate dimensions: 7 cm diameter, 5.8 mm thickness) were exposed to radiant heating (nominally 50 kW m-2 across their top surface) in an anaerobic environment. Samples were insulated at their back surface and continuously heated until complete decomposition was observed. Test boundary conditions (e.g., time- and spatially-resolved measurements of incident radiant heat flux; chamber wall temperatures) were carefully characterized.Six additional tests were also conducted to measure the temperature rise of inert materials (Copper and Kaowool PM Insulation) exposed to the same conditions (i.e., Nitrogen flow rate + incident radiant heat flux) as used during tests on PMMA samples. These test results may be used to validate material thermophysical properties and boundary conditions (e.g., convection heat transfer) controlling heat transfer in this system.
