Tire-derived fuel cofiring test in a pulverized coal utility boiler. Final report
- Iowa State Univ., Ames, IA (United States). Dept. of Mechanical Engineering
In recent years, several states have enacted legislation that outlaws the landfilling of whole tires and forces the implementation of various integrated waste management alternatives to dispose of passenger car and truck tires. Alternate disposal options include source reduction, recycling, composting, incineration, and, as a last resort, landfilling of only shredded tires in conventional landfills or in lined monofills, as required by several states. The high energy content of scrap tires, 13,000-16,000 Btu/lb, has resulted in the use of processed tires as tire-derived fuel (TDF). Previous TDF applications include cement kilns, fluidized bed combustion, stoker, and cyclone-fired boilers. Up to now, no data have been reported for cofiring TDF with coal in pulverized coal boilers. This report presents the results of a Phase I feasibility test program conducted in a 65-MW Babcock and Wilcox pulverized coal steam generator at the City of Ames, Iowa, Municipal Power Plant. This unit currently cofires western coal with refuse-derived fuel (RDF) and utilizes a bottom dump grate to ensure the complete combustion of RDF in the furnace.
