摘要： Systems and generating power in an organic Rankine cycle (ORC) operation to supply electrical power. In embodiments, an inlet temperature of a flow of gas from a source to an ORC unit may be determined. The source may connect to a main pipeline. The main pipeline may connect to a supply pipeline. The supply pipeline may connect to the ORC unit thereby to allow gas to flow from the source to the ORC unit. Heat from the flow of gas may cause the ORC unit to generate electrical power. The outlet temperature of the flow of the gas from the ORC unit to a return pipe may be determined. A flow of working fluid may be adjusted to a percentage sufficient to maintain temperature of the flow of compressed gas within the selected operating temperature range.

摘要： A heat recovery system arranged to be used together with a first closed loop system (S1) configured as a first closed-loop thermodynamic Rankine cycle system, to convert heat from a heat generating unit (1) into electrical energy (E). Said heat recovery system comprising a second closed loop system (S2) comprising a second system working medium (W2) configured as a second closed-loop thermodynamic Rankine cycle system arranged to convert the heat in at least one heat stream (HS1) generated by the heat generating unit (1) into a first batch (E1) of electrical energy (E) and a third closed loop system (S3) comprising a circulating third system working medium (W3). In the second closed-loop thermodynamic Rankine cycle system the condensation heat enthalpy of a vaporised second working medium (W2) is transferred to said third system working medium (W3) and the heat from the third system working medium (W3) is used as an initial thermal input to the second closed loop system (S2), thus converting heat from the third system working medium (W3) into a second batch (E2) of electrical energy (E). The invention also relates to a method to use a heat recovery system together with a first closed loop system configured as a first closed-loop thermodynamic Rankine cycle system, to convert heat from a heat generating unit into electrical energy.

摘要： A method for operating a closed loop regenerative thermodynamic power generation cycle system is presented. The method includes supplying a high-temperature working fluid stream at a first pressure P1 to an expander, and extracting a partially expanded high temperature working fluid stream from the expander at a second pressure P2. Each of the first pressure P1 and the second pressure P2, are higher than a critical pressure of the working fluid; and the second pressure P2 is lower than P1. The method further includes regeneratively supplying the extracted high temperature working fluid stream at the second pressure P2 to a low temperature working fluid stream at the first pressure P1. A closed loop regenerative thermodynamic power generation cycle system is also presented.

摘要： A boiler includes one or more evaporators configured to heat water which has flowed therein to a specific heat maximum temperature at constant pressure or more in which a specific heat at constant pressure is maximized using a heated fluid and one or more reheaters configured to heat the steam which has come from the boiler using the heated fluid. All the reheaters configured to supply steam to a low-pressure steam turbine are disposed only at a downstream side of the high-pressure evaporator. All the reheaters heat reheating steam (FRHS) containing steam which has passed through a high-pressure steam turbine configured to receive steam supplied from the high-pressure evaporator and having a temperature lower than a specific heat maximum temperature at constant pressure in the high-pressure evaporator to less than the specific heat maximum temperature at constant pressure.
