摘要： A method and controller of dynamically determining a current system curve in a heat power system (1), in which the heat power system (1) comprises a regulator (40; 41) and sensors (10; 12; 15; 16). The controller (100) controls an output of the regulator (40; 41) to find the current system curve, collects and checks sensor values with limited accuracy to determine if properties of the sensor values indicate that a point of the current system curve has been reached. When at least two points are found the controller models the current system curve by linear interpolation between the first and second point of the current system curve.

摘要： A method which allows the ejection of non-condensable gases, notably air, from a closed loop power generation process or heat pump system, is disclosed. A vessel in which a working fluid is absorbed or condensed can be separated from the power generation processes by valves. Residual gas comprising C02, non-condensable gas such as air, water and alkaline materials including amines may be compressed by raising the liquid level in said vessel. The concurrent pressure increase leads to the selective absorption of C02 by alkaline materials. In simpler embodiments, mainly air is removed from one- or two-component processes. Following the compression, non-condensable gas may be vented, optionally through a filter. The method is simple and economic as vacuum pumps may be omitted. The method is useful for any power generation and Rankine cycle, and particularly useful for the power generation process known as C3 or Carbon Carrier Cycle.

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： Expansion machines in thermodynamic cycles operate at low pressures, i.e. below 10 bar. The interplay among components including gas generator, expansion machine, heat exchangers and pressure reduction device (absorber or condenser) is optimized, resulting in configurations operating at the lowest achievable cost level. A single stage radial turbine characterized by a pressure ratio of 5-10, a dimensionless speed of about 0.7 and a loading coefficient of 0.7 is a preferred expansion machine for certain thermodynamic cycles involving CO2 gas to permit such radial turbines to operate close to their optimum design specification and highest efficiency level. Methods to handle liquids which may condense within or inside the turbine are also disclosed, as well as methods to handle axial pressure on bearings and methods to protect lubricant in bearings.

摘要： The present invention relates to a system for eliminating the presence of droplets in a first medium of a heat exchanger. The heat exchanger has an inlet port and an outlet port for the first medium as well as an inlet port and an outlet port for a second medium. The system comprises (a) a device for regulating the flow of the first medium into the heat exchanger, (b) a first temperature sensor array for measuring the temperature of the first medium exiting the heat exchanger, and (c) a controller for regulating flow of the first medium into the heat exchanger. The system further comprises a second temperature sensor array for measuring the temperature of the second medium entering the heat exchanger. The controller regulates the flow of the first medium into the heat exchanger based on data received from the first temperature sensor array and second temperature sensor array.
