Abstract. The objective of the TRW project was to generate a data base for equipment selection and design of the front end fuel delivery system for new coal water mixture (CWM) installations and for retrofits of existing fuel oil furnaces to CWMs. The project involved evaluating the performance of pumps and other plant equipment, pipes, fittings, valves, and instruments with

EQUIPMENT SELECTION b) Face Supports. While it is frequently argued (correctly) that all items on a longwall face have to be considered as parts of an integrated unit and be fully compatible, it cannot be denied that poorly designed and inadequate roof supports are likely to have a greater effect on results than other items, and to that extent are more important.
