Low Emission Combustor Technology Program. Final report, October 1, 1982-October 31, 1984. [Multiannular Swirl Burner]
Purpose is to evaluate coal water mixture (CWM) in a low emissions staged rich-lean combustor for stationary combustion turbines. This evaluation was made with the Multiannular Swirl Burner (MASB). The MASB configuration was scaled up from the 5-inch diameter previously tested to a 10-inch diameter and modified for the combustion of CWM and for testing at 3 to 10 atmospheres pressure and 2000/sup 0/F (1094/sup 0/C) turbine inlet temperature. This testing was performed in the Westinghouse Advanced Combustor Development Rig at Concordville, Pa. Testing was done with CWM and No. 2 fuel oil for comparison. In addition, No. 2 fuel oil doped with pyridine was used to simulate the effect of fuel bound nitrogen on NO/sub x/ production. The design of the MASB for CWM combustion has encompassed several subtasks which provided valuable design data. These include numerical combustor flow field calculations by the computer code CORA 2-83, nozzle spray tests on CWM to select the proper nozzle, and the selection of the appropriate CWM. Test results to date on the MASB operating in both the rich-lean mode and lean-lean mode indicate that CWM combustion in a metal walled combustor such as the MASB is feasible. The NO/sub x/ results for oil show an increase in the NO/sub x/ from the 5-inch MASB obtained previously. Combustion efficiencies greater than 99.9% were obtained on oil. CWM combustion with a methane gas pilot has shown combustion efficiencies up to 99.5%. However, combustion to date of CWM alone has only shown combustion efficiencies up to 53%.
