Description
This publication was designed to give the performance curves for Organic Rankine Cycle and Supercritical CO2 Brayton Cycle.
ORC: Primarily designed for utilization of waste heat with low grade temperature sources, the charts for Organic Rankine Cycle can utilize temperatures below 212 F or 100 C and up to 180 C for standard refrigerants such as R134a or R245fa. The performance curves are standardized for 1 gallon per minute (3.785 liters per minute) input flow rate from the heat source, so that the user can input their heat flow rate and multiply that by figures presented. Efficiencies utilizing low grade temperatures can be three to 15 percent utilizing the ORC system.
Brayton Cycle: Primarily designed for utilization of any heat with low to high grade temperature sources, the charts for the Brayton Cycle can utilize temperatures from 88 F or 31 C and over 550 C for CO2. The performance curves are standardized for 1 gallon per minute (3.785 liters per minute) input flow rate from the heat source, so that the user can input their heat flow rate and multiply that by figures presented. Brayton Cycle with CO2 has the potential to have an overall efficiency of up to and may exceed 45 percent.
Working Fluid: Research and development is currently being done to build a closed-cycle gas turbine to utilize the high power density of carbon dioxide. The properties of CO2 exhibit high thermal efficiencies and power generation at or above 500 C, which may exceed 45 percent. For producing electrical power, this can result in a potential of increase of 20 to 40 percent per unit of fuel.
Both Organic Rankine Cycle and Supercritical CO2 Brayton Cycle can utilize waste heat, which will reduce our dependency on fossil fuels. With Supercritical CO2, there is the potential to increase efficiency of fossil fuels, nuclear and other topping cycle power generation of 10 to 40 percent.
Advantages of Brayton Cycle: The primary advantage of using a closed-loop Supercritical CO2 cycle is that you can use any high grade thermal energy source. This includes fossil fuels such as natural gas, diesel and coal and renewable energy sources such as hot geothermal, biomass, waste heat and solar thermal. Using the Brayton Cycle and Organic Rankine Cycle may allow the use of cascading energy production systems.
Chart Data: All of the performance charts and data contained within this document was originated and commissioned by Infinity Turbine LLC, by a certified refrigerant technician. Qualifications of refrigerant technician: Johns Hopkins University, Maryland Masters of Mechanical Engineering Specializing in Thermo-fluid mechanics and a Bachelors of Science in Mechanical Engineering with over nine years in work experience in a refrigeration engineer and product development career.
