Summary

Public Service Company of Colorado is continuing management of the Integrated Dry NOₓ/SO₂ Emissions Control System. The major emphasis this quarter has been on completion of the remaining construction of the system and startup and checkout of the equipment. The low-NOₓ burners have operated since their startup on May 30, 1992 without problem and no unit outages have been experienced due to their operation. All combustion system punch list items have been complete and plant management is very happy with the operation of the new system. Phase 3 operations began on August 3, 1992 with the initiation of testing of the combustion modifications. Preliminary results indicate that the modifications have been very effective and NOₓ emissions have been reduced by nearly 70% to approximately 0.4 lb/MMBtu. These reductions were possible while not negatively affecting fly ash unburned carbon or carbon monoxide emissions. Testing of the burner system will continue through October 1992. Construction of the dry sorbent injection system is now complete and the equipment is ready for operation. A few punchlist items remain but these will not affect system operations. All equipment has been operated dry without injecting reagent. A shipment of reagent will be received next quarter when final system startup will occur. Major construction of the humidification system is complete. The dry ash system was completed this quarter and has operated continuously from mid September.
