Definitions

  • This invention relates to power production from low temperature heat sources, where the available temperature is too low for a steam cycle, for example, from a flow of a single phase fluid, such as pressurised hot water. Examples of this are found occasionally in industrial processes, and are more widely available from geothermal brines obtained from natural aquifers or possibly, from artificially created aquifers obtained from the deep drilling and fracturing of rock formations in what is known as Hot Dry Rock (HDR) .
  • HDR Hot Dry Rock
  • the hot liquid is then expanded in a two-phase expander and then condensed in an air or water cooled condenser. It is then repressurised in a feed pump and returned to the heater to complete the cycle.

  • a closed cycle method of generating power from a low temperature source of heat including the steps of heating a liquefied volatile fluid under pressure in a heater with heat from the source, expanding the liquid to flash a portion thereof into vapour and thereby generate power, separating remaining liquid from the vapour and further expanding the vapour, condensing the vapour into liquid and pumping the condensed fluid back into the heater.
  • the separated dry vapour may then be expanded at very high efficiency in a conventional vapour turbine of the axial or radial flow type while the liquid may be further expanded in a parallel screw or turboexpander.
  • the separation liquid may be reinjected into the heat exchanger at an intermediate entry point with the aid of an additional feed pump.
  • This has two potential advantages, namely: i) It reduces the total feed pump work, since the flow through the main feed pump is reduced while the additional feed pump does not have to operate over such a high pressure difference. ii) Returning the unexpanded liquid at the intermediate temperature has the effect of improving the cycle efficiency by raising the average temperature at which the heat is supplied in the cycle.
  • Fig. 1 shows an installation for generating power from a source of relatively low temperature heat, for example, a geothermal installation in which brine is injected from a line 11 into a rock formation and thereby heated.

  • a pump 14 delivers a volatile fluid under pressure in • liquid form along a line 15 to the heat exchanger 13 where the liquid is heated in counter-flow to the brine.
  • the volatile liquid enters the heat exchanger 13 at point 1 and leaves at point 2 by way of a line 16, the pressure being sufficient to maintain the fluid in its liquid phase.
  • the heated volatile liquid is supplied by the line 16 to a two-phase expander 17 of the twin screw or radial inflow turbine type (e.g., a Francis turbine) where some of the liquid during expansion flashes into vapour. It is not practical to make a single expander capable of expanding all liquid into vapour so that the fluid leaving the primary expander 17 (at point 3) is a homogenous mixture of liquid and vapour phases .
  • a two-phase expander 17 of the twin screw or radial inflow turbine type e.g., a Francis turbine
  • This homogenous mixture of liquid and vapour is conveyed by a line 19 to a separator 20 of the gravitational or centrifugal type, in which the liquid and vapour phases are substantially separated and delivered respectively to lines 21 and 22.
  • the liquid phase (at point 3') is delivered to a further expander of the twin screw or radial inflow turbine type where some of the liquid flashes into vapour while generating power delivered to a shaft 24.
  • the separated vapour from line 22 (at point 3") is fed to the inlet of a high efficiency turbine 25 of the radial or axial flow type, where it generates further power which may be delivered to the shaft 24 to drive a further generator or other mode G.
  • the exhaust vapour from the expander 23 and turbine 25 is delivered (at point 4' and 4") by lines 26 and 27 to a condenser 28 where the vapour is condensed by heat exchange with a cooling system 29 and the resulting liquid is delivered by a line 30 (at point 5) to the inlet of the pump 14.
  • the cycles shown in the graphs in Figs . 2 , 4, 6, 8 and 10 result from using a working fluid having a high number of atoms per molecule, such as n-pentane.

  • the temperature-entropy diagram for the vapour phase has a positive slope as opposed to water / steam where the corresponding slope for the vapour phase is negative.
  • the length of the line 3" -3 (which represents the portion of the mixture still in liquid form) is much less than the length of the line 3-3' (which represents the portion now in vapour phase) . Accordingly, the dryness of the homogenous mixture leaving the expander 17 is at least 70%. In contrast in the case of water, the mixture would only comprise about 10-20% vapour.
  • Fig. 3 shows a modification of the installation shown in Fig. 1, for use where the contribution of the liquid expansion in the expander 23 to the total power generated by the system is not large, either because the relative mass of separated liquid is small or the volume ratio of expansion is too high or both.
  • the relatively small liquid phase leaving the separator 20 is fed by a line 31 through a further feed pump 32, which delivers the liquid to an intermediate point of the heat exchanger 13.
  • This has three potential advantages: i) It reduces the total feed pump work, since the flow through the main feed pump is reduced while the additional feed pump does not have to operate over such a high pressure difference. This effectively recovers some 12% of the power lost by omitting the second two-phase expander .
  • FIG. 5 An alternative arrangement to that shown in Fig. 3 is shown in Fig. 5.
  • a two-stage feed pump is normally required formed by first and second pump stages 41 and 42 connected in series (or by two pumps by a line 43) .
  • the fluid is admitted into the second feed pump stage by way of the line 43. This then raises the liquid admission temperature to the heater and hence results in less recovery of heat from the brine but with no other performance penalty and it still results in a correspondingly reduced size condenser.
  • the liquid phase from the separator is delivered by a line 121 to a throttle valve 34 from which the liquid phase is returned to the condenser 28 with a drop in pressure to that of the vapour leaving the expander 25.
  • a throttle valve 34 from which the liquid phase is returned to the condenser 28 with a drop in pressure to that of the vapour leaving the expander 25.
  • the estimated values of recoverable power outputs from each expander are based on expansion efficiencies of 80% for the first stage two-phase expander, 40%-60%, depending on the entry conditions, for the second stage two- phase expander and 85% for the dry vapour expander and are given in the following table. These component efficiencies represent experimentally verified values for the first stage liquid and dry vapour expanders and estimates for the second stage liquid expander. The lower values assumed for this latter component are due to the fact that very high volume ratios are incurred in this case and hence only partial recovery of the power is possible within it.
  • the first stage two-phase expansion has a volume ratio of approximately 9:1, when separating at 125°C increasing to approximately 25:1 at a separation temperature of 90C.
  • the second stage two-phase expansion is of the order of 100:1 and varies far less with the separation temperature.
  • the dry vapour expander requires a volume ratio of 14:1 at 125°C admission temperature falling to only 6:1 at 90°C admission.
  • the very high volume ratio of the second stage two-phase expansion implies that its efficiency is low, but since the available energy from this is relatively small, the penalty for this in terms of overall expansion efficiency is not so significant.

Abstract

Un fluide présentant une pente positive pour une partie vaporeuse de son diagramme température-entropie, tel n-pentane, est chauffé en tant que liquide sous pression dans un échangeur thermique (13) au moyen de la chaleur issue de la source (12) et réparti de manière à générer de la puissance dans un extenseur à deux phases (17) afin de former un mélange homogène de liquide et de vapeur qui est distribué à un séparateur (20). La vapeur séparée est répandue dans une turbine (25) afin de générer davantage de puissance avant d'être condensée dans un condensateur (28), le condensat étant fourni à une première pompe d'alimentation (41). La sortie de la pompe (41) et la quantité relativement faible de liquide provenant du séparateur (20) sont renvoyées au moyen d'une deuxième pompe d'alimentation (42) à l'échangeur thermique (13). Dans un arrangement modifié, le liquide issu du séparateur est renvoyé au moyen d'une autre pompe d'alimentation à un point intermédiaire de l'échangeur thermique.
