In this paper is given the analysis of thermal and technological circuits of sugar- refineries wich causes increasing of expenditure of fuel and primary steam. There are suggest some explications about maked negativ effects. There are indicated opportunities of improvement of thermal circuits for reducing the dependence of consumption of primary steam from quality of sugar beet. Increasing of efficiency of thermal circuits and installation of steam-jet compressors permits increasing of coefiicient of thermodynamic efficiency for evaporation station and improvement of technological processes.
