POWER GENERATING METHOD EMPLOYING OPERATING FLUID HAVING VAPOR-LIQUID EQUILIBRIUM

摘要

PURPOSE: To improve power generating efficiency by a method wherein dilute solutions of two kinds of operating fluids are poured at the inlet side of a first condenser to reduce the condensing densities of them and vapor-liquid separation of the condensed solution from the first condenser is effected while the separated condensed solution and the separated vapor are contacted in a second condenser in the form of counterflow. ;CONSTITUTION: A first and second condensers 21, 22 are provided in series to the exhaust gas of a turbine 12 and a vapor-liquid separator 4 is provided between both condensers. The dilute solution of the first condenser 21 is poured into the exhaust gas of the turbine in a pipeline 37 at the inlet side of the first condenser by a pump 36. The first condenser 21 condensates a part of the dilute solution and evaporates two kinds of operating fluids passing through the first condenser 21 under this process. The vaporized gas and the dilute solution are sent into a condenser 3 to condensate them. On the other hand, condensed liquid in the first condenser 21 is separated into vapor and liquid in a vapor-liquid separator 4. Separated condensed liquid and non- condensed vapor are sent into the second condenser 22 to contact them with each other in the form of counterflow.;COPYRIGHT: (C)1995,JPO
