Abstract

Northern Indiana Public Service Company (NIPSCO), with support from USDOE-EERE, the USDOE Federal Energy Technology Center, and EPRI, is installing a materials handling system to fire a combination of wood waste and petroleum coke with the base coal in the No.7 boiler of Bailly Generating Station. The No.7 boiler is a 160 MW{sub e} (net) unit fired with four cyclones. It is typically fired with a blend of Illinois coal and Western coal. The gaseous combustion products from this boiler are ducted to a precipitator and then to a Pure Air scrubber for sulfur oxides removal. The Pure Air scrubber converts the SO{sub 2} into artificial gypsum. Typically the unit burns about 70 tons/hr of coal at full load. The Bailly Generating Station program, being implemented by Foster Wheeler Development Corporation, involves blending petroleum coke and wood waste with coal for combination opportunity fuel firing. Multiple fuel firing is intended to capture the advantages of each fuel: high volatility of biofuels and high Btu content of petroleum coke are among these characteristics. The objective of the program, then, is to reduce fuel costs at the station while improving combustion. The program involves constructing a fuel handling and blending system, andmore »« less

Blending opportunity fuels with coal for efficiency and environmental benefit

Conference Tillman, D; Hus, P

Northern Indiana Public Service Company (NIPSCO) has developed a long term demonstration firing biomass and petroleum coke with coal at its Bailly Generating Station boiler No. 7, a 160 MWe (net) cyclone boiler. This demonstration, funded by the US Department of Energy (USDOE) Office of Energy Efficiency and Renewable Energy (EERE) and the USDOE National Energy Technology Laboratory (NETL), has been developed as part of the Electric Power Research Institute (EPRI) biomass cofiring demonstration program. The NIPSCO demonstration program--the triburn program--has involved designing and constructing a fuel preparation and blending facility. It then involved extensive testing of firing clean urbanmore »« less
Opportunity fuels at NIPSCO's Bailly generating station (or ``Can one project really meet the needs of fuels, electric production and environmental affairs?'')

Conference Hus, P; Benda, D; Schmitt, J

The term ``opportunity fuels'' was a new expression for NIPSCO's Bailly Generating Station in 1998. As NIPSCO approaches the new millennium, Bailly has gained new experience on co-firing two such opportunity fuels with coal. The opportunity fuels are biomass, in the form of waste wood, and petroleum coke. The synergies of the two have produced some impressive results. The fuels department has taken a new interest in what may be an opportunity to reduce NOx, manage fuel cost, improve boiler efficiency and add a renewable fuel to NIPSCO's coal-only fuel portfolio. The results of NIPSCO coal, biomass and petroleum cokemore »« less
Commercializing biomass-coal cofiring: The process, status, and prospect

Conference Tillman, D; Hughes, E; Plasynski, S

Recently there has been considerable emphasis on cofiring biomass opportunity fuels with coal in pulverized coal (PC) and cyclone boilers owned and operated by electricity generating utilities in order to address such issues as potential portfolio standards, voluntary actions to reduce fossil CO{sub 2} emissions, customer service, and the generation of green power within the context of deregulation. Biomass fuels include such materials as wood waste, short rotation woody crops, short rotation herbaceous crops (e.g., switchgrass), alfalfa stems, and various types of manure.

USDOE/EPRI BIOMASS COFIRING COOPERATIVE AGREEMENT

Technical Report Tillman, D; Hughes, E

The Eleventh Quarter of the USDOE-EPRI contract, April 1, 1999 through June 30, 1999, was characterized by extensive testing at the Seward cofiring demonstration of GPU Genco and the Bailly Unit No.7 demonstration of NIPSCO. Technical work that proceeded during the eleventh quarter of the contract included the following: Testing at up to {approx}15 percent cofiring on a mass basis ({approx}7 percent cofiring on a Btu basis) at the Seward Generating Station No.12 boiler, focusing upon the operability of the separate injection system and the combustion/emission formation characteristics of the cofiring process; and Testing at up to {approx}10 percent cofiringmore »« less
