Development and Demonstration of an Electric Heat Pump for Waste-Heat Recovery in Industry. Preliminary Design Report

摘要

A high-temperature heat pump is being developed for demonstration of waste-heat recovery in industry. The design of a prototypical unit to be used to recover heat from the vapor effluent of a thermomechanical pulping unit in a paper mill is outlined. The output capacity of the unit is 30 x 10 exp 6 Btu/h in the form of process steam delivered at 50 psig with 20 exp 0 F superheat (318 exp 0 F). A functional description of the heat-pump system is given along with a thermodynamic analysis of the cycle. The various subsystems, controls, and major components are also described and a safety analysis presented. (ERA citation 08:012621)
