Description

The primary objective of this Clean Coal Technology project is to evaluate the use of Gas Reburning and Low NO{sub x} Burners (GR-LNB) for NO{sub x} emission control from a wall fired boiler. This project is being conducted in three phases at the host site, a 172 MW{sub e} wall fired boiler of Public Service Company of Colorado, Cherokee Unit 3 in Denver, Colorado: Phase I, design and permitting has been completed on June 30, 1992; Phase II, construction and start-up has been completed on September 1991; and Phase III, operation, data collection, reporting and disposition. Phase III activities during ... continued below

This project is being conducted in three phases at the host site, a 172 MW{sub e} wall fired boiler of Public Service Company of Colorado, Cherokee Unit 3 in Denver, Colorado: Phase I, design and permitting has been completed on June 30, 1992; Phase II, construction and start-up has been completed on September 1991; and Phase III, operation, data collection, reporting and disposition. Phase III activities during this reporting period involved the following: compilation, analysis and assembly of the final report and initiation of restoration activities; restoration of the gas reburning system involving removal of the flue gas recirculation system (permanent Second Generation Gas Reburning); and participants meeting and reburning workshop. Long term testing of the equipment demonstrated an average NO{sub x} reduction of 65% using 18% gas heat input. After removing the flue gas recirculation system, (Second Generation GR), an average NO{sub x} of 64% was achieved using 13% gas heat input. The project goal of 70% reduction was achieved, but no on an average basis due to the load requirements of the utility.
