National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Barrier Issues to the Utilization of Biomass. (Final Technical Report.)

DE2005835032

Publication Date	2002
Personal Author	Folkedahl, B. C.; Gunderson, J. R.; Schmidt, D. D.; Weber, G. F.; Zygarlicke, C. J.
Page Count	138
Abstract	The goal of this project was to identify the primary ash mechanisms related to grate clinkering and heat exchange surface fouling associated with cofiring coal and biomass-specifically wood and agricultural residuals-in grate-fired systems, leading to future mitigation of these problems. The specific technical objectives of the project were: Modification of an existing pilot-scale combustion system to simulate a grate-fired system; Verification testing of the simulator; Laboratory-scale testing and fuel characterization to determine ash formation and potential fouling mechanisms and to optimize activities in the modified pilot-scale system; Pilot-scale testing in the grate-fired system. The resulting data were used to elucidate ashrelated problems during coal-biomass cofiring and offer a range of potential solutions.
