Abstract

With great concern over efficient energy usage and thermal pollution in Hong Kong, it is essential for energy intensive industries to hearken to such concern through actual reductions in energy consumption and thermal pollution. This leads to an essential study on the ways of limiting energy wastage and thermal pollution in a local textile finishing processes factory. The main activity of this factory involves singeing, desizing, scouring, hot washing, bleaching, mercerizing, dyeing, printing, soaping, drying and finishing of cotton fabric. In this paper, engineering measures to limit heat energy wastage discharged from continuous bleaching machine, drying chamber, boiler stack exhaust and blowdown are discussed. The cost-benefit analysis for the proposed energy conse
