PURPOSE:To boost the generating pressure of the bubble pump by a method wherein the bubble pump is connected in series to separate vapor from the two phase flow of gas and liquid discharged from an evaporating pipe and liquid part is supplied to a descending pipe in the next stage. CONSTITUTION:Oparating fluid 102 is introduced from a suction pipe 6 into a suction chamber 5, the heat thereof is exchanged with heat source fluid 101 in the evaporation pipe 1 to make the operating fluid into two phase flow under boiling, thereafter, gas and liquid are separated in a condensing chamber 4. In order not to reduce a pressure in the condensing chamber by the vapor cooled in the condensing pipe 3, the vapor is liquefied under controlling the flow amount of cooling fluid series 103 by a pressure detector 14, a pressure setter 15 and a flow amount regulating valve 16 and operations in which the liquefied vapor is sent into the suction pipe 6 in the next stage from a discharging pipe 7 together with the operating fluid are repeated to boost the pressure sequentially. |
