This report details the activities, facilities, and equipment used to sample lignite slag from the Department of Energy Grand Forks Energy Technology Center's slagging fixed-bed gasifier. Explanation of the sampling location, discussion of the sampling technique (in accordance with the Fossil Energy Waste General Sampling Guideline), and a review of the gasifier design are included in this report. Versar Inc.'s responsibility in this project involves the sampling of waste materials and the blending, containerization, labeling, and distribution of the samples. Distribution of the samples to laboratories selected by DOE was coordinated through the Versar office in Springfield, Virginia; therefore, no detailed description of distribution or analytical results will be provided in this document.
