An atmospheric combustion facility was designed and constructed to study the effects of turbulent mixing and the kinetic processes occurring in pulverized coal combustors. The experimental test program includes 52 reacting coal/air tests and 24 reacting char/air tests. Test variables include percent coal loading in the primary stream, percent excess air, coal volatility, and particle size, primary/secondary stream velocity ratio, primary and secondary stream injection temperatures, and the injection angle of the secondary stream to the primary stream. The reactor was constructed in sections, one of which is a probe section. The probes allow for simultaneous gas/particulate sampling and can be positioned in the reactor to sample both radially and axially. Use of gas and particle tracers coupled with probe sample analysis will enable the determination of: (1) the local extent of mixing of primary and secondary gases, (2) the local extent of particle dispersion, (3) the local extent of particle reaction, and (4) the local extent of pollutant formation. Checkout tests on the facility were completed and methane/air and coal/air flames have been stabilized. Trial tests with both water cooled and direct water quench probes are under way.
