Clean coal technology program/solid waste management.

摘要

This report addresses solid waste management from generic clean coal technologies (CCT) processes, where 90% sulfur reduction is achieved. The technologies evaluated are: Atmospheric Fluidized-Bed Combustion (AFBC), Pressurized Fluidized-Bed Combustion (PFBC), Gasification, Advanced Slagging Combustion, Boiler and Ductwork Sorbent Injection, Advanced Tailgas Cleanup, Physical Coal Preparation, and Chemical and Biological Coal Preparation. This report opens with a discussion of existing, proposed, and possible solid waste regulations as they apply to CCT. To help put CCT solid waste management in perspective, management of boiler ash and fly ash from conventional utility power plants is examined. Then the CCT processes are discussed. Each chapter is subdivided into the following subsections: Technology; Applications/Researchers; Quantities and Characteristics of Solid Wastes; Land Disposal and Leachates; Byproduct Use; Waste Minimization; Data Gaps and Research Needs. There is also a short section on NO(sub x) removal followed by a general discussion on solid waste management. The report concludes with a list of general recommendations as related to solid waste management and CCT-3 solicitations. 18 tabs.
