Development of a Coal/Water-Slurry-Fueled Diesel Engine for Industrial Cogeneration: Task 2.0, Fuel Preparation, Beneficiation and Handling

摘要

This project is part of a longer-range program whose objective is to establish a high efficiency prototype industrial power system that can burn coal directly. The power system consists of a slow-speed, two-stroke diesel engine and a fuel preparation system which provides clean micronized coal in a water slurry for use as the primary fuel. The project is divided into five tasks. This topical report deals with the subject of Task 2: Fuel Preparation, Beneficiation and Handling. The first part of the report consists of a comparative evaluation of the beneficiation technologies that can reduce the ash content in the coal to less than 1 percent, and a comparative analysis of the most important factors affecting the economics of these processes as a whole. The second part is a report of the slurry procurement effort and the preliminary screening tests that were performed on the slurries to determine which one will be used for the diesel engine tests scheduled.
