Abstract

PURPOSE:The above mentioned apparatus, dissolving noneffective stages at partial load and enable a highly efficient operation, by providing the bypass passage mixing the fluid having a higher temperature than the fluid passing through the heat transmission tube of evaporation room of heat recovery part. CONSTITUTION:Higher temperature fluid than that of in the heat transmission tube 9 at the point 8 of evaporation room inlet in the evaporator of heat recovery part 11, is flowed in the tube 9 through the bypass piping 6 and the valve 7 and the temperature of the fluid in the tube 9 of stages of higher temperature side than the point 8, is elevated. Temperature difference between stages of these stages, is made small and flash fluid temperature of stages of lower temperature side than the point 8, is made high, by repressing the flash evaporation of these stages. By the above method, the flash evaporation at non-flash stages is carried out. Hereby, heat is given to the fluid in the tube 9 and temperature before mixing a high temperature fluid at the point 8, is made high. Thus, the quantity of bypass flowing is able to decrease or is made zero by the valve 7 and hereafter, stationary operation is able to carry out at the above condition. Also, the liquid levle is generally decreased and a highly efficient partial load operation is able to carry out.
