Dye Bath Waste Heat Recovery in Dyeing Process

Dyeing section consisting of nine dyeing processes is analysed. These processes are great consumers of heat energy that is used for warming of bath in which textile is dyed. Dye baths from some phases or sub-phases of processes are rejected into sewage despite their significant waste heat potential. Generalised model for estimation of dye bath waste heat potential is proposed and is applied to analysed dyeing section. The same model is also applied to each process as itself that resulted in possible heat energy saving up to 53, 9%.
