USE OF COAL AND COAL-DERIVED FUELS IN TOTAL ENERGY SYSTEMS FOR Ml US APPLICATIONS VolumeⅡ

摘要

This program had its inception some years ago when HUD foresaw the impending energy shortage and initiated work on small total energy systems for use with new housing complexes. In these systems the waste heat from the thermodynamic cycle used to generate elec¬tricity is used to heat both domestic hot water and buildings in the winter and for absorption air conditioning systems in the summer. ORNL has been assisting HUD in this work, first by looking at the problems of supplying heat to building complexes from district heating systems tied to central stations,1 and subsequently by examining various small total energy systems. Hundreds of such systems are in use currently in the U.S. making use of diesel or gas engines or small gas turbines.
