What is the rankine cycle?
Rankin cycle is a term describing a process that uses heat to do work. It is named after Scottish engineer and physics William John Macquorn Rankine. Generally, heat produces a steam that controls the turbine. It is primarily used to produce electricity and since 2011 it has been approximately 80% of electricity used worldwide. In the boiler, the external heat source converts the liquid working fluid into a steam that powered the turbine and then condenses into a liquid that is pumped back to the boiler. Steam steam leaves the boiler at a high temperature-1,000 ° F (538 ° C) -a pressure-4,500 PSIG (31,026.4 kpag) -A is the expansion of this hot, high-pressure gas that drives Shaft to produce electricity or drive. Rankine effectiveness can reach approximately 40%.
This process is the basis for most power plants where fuel is used as a source of heat to produce electricTřina. Fuel may be oil, coal, gas, biomass or nuclear; Because the heat source is external anything that can create sufficient heat. Rankine cycle technology on a smaller scale can also be used to use waste heat from traditional power plants. For example, gas combustion power plants use internal combustion turbines that create hot exhaust gas, as unlike Rankine Cycle, they do not work in a closed loop. They can be combined with a rankine cycle generator, which uses hot gas to make steam, significantly improves energy efficiency.
fluids other than water can be used in Rankine cycle, where they offer advantages specific applications. For example, power plants that work in very cold conditions may require fluid with a lower freezing point. Several organic fluids were used and the Pentan was successfully used in Rankine Cycle generator, which uses hot exhaust gas from the gas power plant as a source of heat, as described above. The process that uses this wayA á organic fluid, is known as an organic ranch (orc) cycle.
Many renewable energy projects use ORC technology to create energy. It is often used in geothermal power plants and this system has been modified to be used in some solar power plants where sunlight is aimed at ensuring heat to control cycle. The small generators that use this technology were available to use waste heat from various industrial processes.
