The closed cycle gas turbine works on the basis of the Brayton cycle or Joule’s cycle. A schematic diagram of a closed cycle gas turbine sections (Reference: ) Working Principle of Closed Cycle Gas Turbine
The gas turbine drives the generator, compressor, and cooling chamber. This diagram shows the simple schematic of a closed cycle gas turbine in detail. In this type, the ratios of pressure, temperature, and air velocity will be constant. The thermodynamic cycle means that working fluid is used repeatedly without ever leaving the system.Ī compressor, a heat chamber, a gas turbine, and a cooling chamber work together to circulate air continuously within this type of turbine. This Recirculating turbine works on the Brayton cycle. It uses heat that comes from an external source. air, nitrogen, helium, argon, etc.) as the working fluid. Basics of Closed Cycle Gas TurbineĮssentially, a closed cycle gas turbine is a thermodynamic system that uses a gas (e.g. This article provides an overview of the turbine, its working principles, and its advantages and disadvantages. A solution to this problem is to use a superior working medium (air, helium, argon, hydrogen, or neon) that does not mix with the fuel inside the combustion chamber.Ī closed cycle method also has the advantage of rejecting heat from exhaust gases via re-coolers, re-heaters, or heat exchangers. The main drawback of open-cycle turbines is corrosion and erosion of turbine blades. In order to resolve the disadvantages associated with an open-cycle gas turbine process, a closed cycle gas turbine method is developed. Warehouse Equipment and Supplies Companies.
