The presented mathematical model of a four-effect evaporator with turbocompressor enables easily to compare the results of four fariants of working conditions and the advantages of proper juice concentration. Minimum steam comsumption is obtained in the sugar factory when taking full advantage of vapours from expansion of condensates, using condensates to heat raw juice and then to supply the extractor with simultaneous steam turbocompressing.
A new appratus for testing the quality of condensate opcrated in the sugar factory during whole campaign. That analyser protects steam boilers against damage caused by presence of sugar in water feeding the boilers.
