Book excerpt: This research program was initiated to characterize problems associated with retrofitting existing utlity boilers with low- and medium-Btu gases manufactured from commercially available coal conversion processes. All the experimental results were gathered from a pilot-scale furnace fired with a movable-vane boiler burner at a heat input of 0.66 MW (2,250,000 Btu/h). The low- and medium-Btu gases tested ranged in heating value from 3.7 to 11.2 MJ/m3 (100 to 300 Btu/SCF). They were synthetically produced with a natural gas reformer system. Data were collected to permit a comparison between natural gas and low-Btu gases in the areas of flame stability, flame length, flame emissivity, furnace efficiency, and NOx emissions. Flame stability was found to be very sensitive to fuel jet volocity. An injection velocity of 30.5 m/s (100 ft/s) was found to be optimum. Flame length decreased with increasing movable vane angle (swirl of the combustion air), and the low- and medium-Btu gases tested were generally shorther than those of natural gas. Good agreement was obtained between measured and calculated flame emissivities. Some boiler modifications would be necessary to maintain rating when burning gases of less thatn 7.5 MJ/m3 (200 Btu/SCF) heating value. NO emissions were ordered by adiabatic flame temperature. The NO emission data yielded an activation energy of 153 k-cal/mole compared to kinetic model predictions of 135 k-cal/mole. The use of adiabatic flame temperature provided a good empirical method of predicting NO emissions for the fuels tested.

However, two developments have increased the significance of oxygen-enhanced combustion-new technologies that produce oxygen less expensively and the increased importance of environmental regulations. Advantages of oxygen-enhanced combustion include less pollutant emissi

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Under the U.S. Department of Energy's Clean Coal Technology Program (Round 3), aproject was completed to demonstrate control of boiler NOX emissions and to a lesserdegree, due to coal replacement, SO2 emissions. The project involved combining GasReburning with Low NOX Burners (GR-LNB) on a coal-fired electric utility boiler todetermine if high levels of NOX reduction (70%) could be achieved. Sponsors of the projectincluded the U.S. Department of Energy, the Gas Research Institute, Public ServiceCompany of Colorado, Colorado Interstate Gas, Electric Power Research Institute, and theEnergy and Environmental Research Corporation. The GR-LNB demonstration wasperformed on Public Service Company of Colorado's (PSCO) Cherokee Unit#3, locatedin Denver, Colorado. This unit is a 172 MW wall-fired boiler that uses ColoradoBituminous, low-sulfur coal. It had a baseline NOX emission level of 0.73 lb/106 Btu usingconventional burners. Low NOX burners are designed to yield lower NOX emissions than conventional burners. However, the NOX control achieved with this technique is limited to 30-50%. Also, withLNBs, CO emissions can increase to above acceptable standards. Gas Reburning (GR)is designed to reduce NOX in the flue gas by staged fuel combustion. This technologyinvolves the introduction of natural gas into the hot furnace flue gas stream. When combined, GR and LNBs minimize NOX emissions and maintain acceptable levels of COemissions. A comprehensive test program was completed, operating over a wide rangeof boiler conditions. Over 4,000 hours of operation were achieved, providing substantialdata. Measurements were taken to quantify reductions in NOX emissions, the impact onboiler equipment and operability and factors influencing costs. The GR-LNB technologyachieved good NOX emission reductions and the goals of the project were achieved. Although the performance of the low NOX burners (supplied by others) was less thanexpected, a NOX reduction of 65% was achieved at an average gas heat input of 18Y0. Theperformance goal of 70% reduction was met on many test runs, but at a higher reburn gasheat input. S02 emissions, based on coal replacement, were reduced by 18Y0. Theperformance goal of 70% reduction was met on many test runs, but at a higher reburn gasheat input. S02 emissions, based on coal replacement, were reduced by 18Y0. Toward the end of the program, a Second Generation gas injection system was installed. Higher injector gas pressures were used that eliminated the need for flue gas recirculationas used in the first generation design. The Second Generation GR resulted in similar NOXreduction performance as that for the First Generation. With an improvement in the LNBperformance in combination with the new gas injection system, the reburn gas could bereduced to 12.5% of the total boiler heat input to achieve al 64?40 reduction in NO, emissions. In addition, the OFA injectors were modified to provide for better mixing tolower CO emissions.

Book excerpt: Coal, still used to generate more than half of the electric power in the U.S., will likely be part of any future global energy plan. But this finite resource is also responsible for 80 percent of the CO2 emissions from power production, and its continued use will require improved processing techniques that are less damaging to the environment and l
