An analysis of textile processes was conducted to determine their applicability to integration into a 50,000 ft/sup 2/ collector field and into a waste heat recovery system. Various processes in a typical carpet finishing plant, a typical cotton/cotton blend finishing plant, and a typical 100% synthetic fabric pressurized beck finishing plant are analyzed. The flat-plate, evacuated tube, and parabolic concentrator are discussed and evaluated. Evaluations of direct heat exchange, closed cycle enhanced recovery, and open cycle enhanced heat recovery techniques as applied to textile processes are presented. Conceptual designs are discussed that use a solar array to produce hot water and use standard boilers to produce process steam and to augment the hot water output when insolation values are insufficient to meet process demands. Conceptual designs and cost estimates are presented for: process water systems with evacuated tube solar collectors; process water system with concentrating-tracking solar collectors; feedwater system with concentrating-tracking solar collectors; templifier and direct exchange waste heat recovery system; direct heat recovery systems; integrated system using enhanced heat recovery and concentrating-tracking solar collectors; integrated system using direct heat recovery and concentrating-tracking solar collectors; integrated system using direct heat recovery, evacuated tube solar collectors and concentrating-tracking solar collectors; and integrated system using enhanced heat recovery, evacuated tube collectors, and concentrating-tracking source collectors. An economic evaluation of the systems is presented using the rate of return method. Results and recommendations are summarized. (MCW)
