Description

"BRAYTON COMBINED CYCLE TURBINE AND ISOBARIC-ADIABATHIC TORBINE AND CONTROL PROCESS FOR THE THERMODYNAMIC CYCLE OF THE COMBINED CYCLE TURBINE MOTOR"

TECHNICAL FIELD OF THE INVENTION

[001] The present invention relates to a combined cycle turbine-type thermal motor formed by one unit operating with the interconnected Brayton cycle and integrated with the other unit operating with the binary cycle of three isobaric and four adiabatic processes.

BACKGROUND OF THE INVENTION

[002] Classical thermodynamics defines three concepts of thermodynamic systems, the open thermodynamic system, the closed thermodynamic system and the isolated thermodynamic system. These three concepts of thermodynamic systems were conceptualized in the nineteenth century in the early days of the creation of the laws of thermodynamics and underlie all motor cycles known to date.

The isolated thermodynamic system is defined as a system in which neither matter nor energy passes through it. Therefore, this concept of thermodynamic system does not offer properties that allow the development of motors.

[004] The open thermodynamic system is defined as a thermodynamic system in which energy and matter can enter and leave this system. Examples of open thermodynamic systems are the Atkinson cycle Otto-cycle internal combustion engines, Sabathe cycle-cycle Otto-diesel internal combustion engine, Rank-exhaustion Brayton cycle-internal combustion cycle Diesel engine from steam to the environment. The materials that come into these systems are fuels and oxygen or fluid working gas or working gas. The energy that enters these systems is heat. The materials that come out of these systems are the combustion or working fluid exhaust, gases and waste, the energies that come out of these systems are the mechanical working energy and part of the heat dissipated.

[005] The closed thermodynamic system is defined as a thermodynamic system in which only energy can enter and leave this system. Examples of closed thermodynamic systems are external combustion engines such as Stirling cycle, Ericsson cycle, Rankine cycle with closed circuit working fluid, Brayton heat cycle or external combustion, Carnot cycle. The energy that enters this system is heat. The energies that come out of this system are the mechanical working energy and part of the heat dissipated, but no matter comes out of these systems, as occurs in the open system.

[006] Both open and closed systems, all working gas mass is exposed to incoming energy, heat or combustion and all of it is exposed to cooling or cooling, that is, working gas mass is constant in their processes and the difference between them is that in the open system the working gas mass goes through the system, and in the closed system the mass remains in the system.

THE CURRENT STATE OF TECHNIQUE

[007] Combined-cycle motors known to date have been invented and designed by uniting in the same system two motor concepts conceived in the nineteenth century, based on open thermodynamic systems or closed thermodynamic systems, the best known are the combined cycles of a Brayton cycle engine with a Rankine cycle engine and the combined cycle of a Diesel cycle engine with a Rankine cycle engine. [008] The basic concept of a combined cycle is a system composed of a motor operating by means of a high temperature source so that the heat waste of this motor is the energy that drives a second motor that requires a lower temperature of operation, both forming a combined system of converting thermal energy into mechanical energy for the same common purpose.

[009] The current state of the art reveals combined cycles formed by a Brayton main cycle motor running on a main source with a temperature above 1000 ° C and with exhaust gases in the range between 600 ° C and 700 ° C and these gases. in turn they are channeled to power another Rankine cycle engine, usually "organic Rankine" (ORC). The conventional Rankine cycle has water as its working fluid, the organic Rankine cycle uses organic fluids, these are more suitable for projects at lower temperatures than those with the conventional Rankine cycle, so they are usually used in combined cycles.

[010] Some of the main disadvantages of the current combined cycles, considering the second machine as a Rankine or organic Rankine cycle engine are the changing of the physical state of the working fluid, that is, there is a liquid phase required by the thermodynamic cycle processes that must controlled, and the heating energy of the liquid phase and the latent phase of state exchange cannot be converted into useful working energy, they are losses imposed by the Rankine concept. This system requires engine items that imply more processes, more weight, more control and more losses, liquid reservoirs, steam generation reservoir, condenser cooler type, condensation reservoir, fluid flow pump in liquid state, control valves of liquid and gaseous processes. This set of features entails additional weight, additional volume, additional thermal losses, reduced overall efficiency and therefore higher pollution rates, higher implementation costs and lower sustainability indices in these projects.

[01 1] The current state of the art from 201 1 has revealed a new concept of thermodynamic system, the so-called hybrid thermodynamic system, and this new system concept has become the basis of support for new motor cycles, motors. differential cycle motors and non-differential binary cycle motors so that these new motor cycles have significant advantages for the creation of new combined cycles. Combined cycles of a Brayton cycle engine with a differential cycle motor, Brayton cycle engine with a binary cycle engine, Diesel cycle engine with a differential cycle engine, Diesel cycle engine with a binary cycle motor can be exemplified. , Otto cycle motor with a differential cycle motor, Otto cycle motor with a binary cycle motor and some other variations.

OBJECTIVES OF THE INVENTION

[012] The major problems of the state of the art, specifically with regard to combined cycles, lie precisely in the second unit that forms the systems, this is usually a Rankine cycle machine, an old machine whose thermodynamic processes impose losses through the need for exchange of physical state of working fluid, heat of liquid phase heating, heat of transformation, latent heat, mechanical units, reservoirs, valve systems, condensers, pumps that add weight, volume, losses and costs.

[013] The aim of the invention is to eliminate some of the existing problems, minimize other problems and offer new possibilities. To achieve these objectives, a new concept of thermal motors has become indispensable and the creation of new motor motors is necessary. so that engine efficiency would no longer be dependent solely on of temperatures. The hybrid system concept and differential and binary cycles, the very characteristic that underlies this new combined cycle concept, eliminates the reliance on efficiency exclusively at temperature. Eliminating the need to change the physical state of work fluids is now representative to reduce machine volume, weight and costs. Therefore the combined cycle formed by a Brayton cycle unit with a binary-isobaric-adiabatic cycle unit constitutes an important, viable evolution for the future of combined cycle systems.

DESCRIPTION OF THE INVENTION

[014] Combined cycle motors are characterized by having two separate thermodynamic units integrated forming a system such that the energy disposed of by the main unit is the power source of the secondary unit and both have an integration of the final mechanical work.

[015] The present concept considers a thermodynamic unit formed by a Brayton 320 cycle turbine engine, which performs a four-process Brayton cycle and a binary-isobaric-adiabatic cycle turbine engine 319, which performs a three-process cycle. isobaric and four adiabatic processes, and so that the input energy, normally by combustion, performs an isobaric expansion process on the Brayton cycle unit, an also isobaric cooling process which gives energy to the isobaric cycle unit expansion process binary, in turn performs an isobaric cooling process by giving to the environment energy that the system as a whole has not converted to work and so that both cycles have a common final work conversion. So these are completely combined cycle turbine engines motors and current combined cycles, which are based solely on open or closed systems. Figure 3 shows the general concept of the invention and figure 4 shows the integration of both thermodynamic cycles forming the combined cycle.

[016] The present invention brings important developments for the conversion of thermal energy to mechanics by the concept of the combination of two distinct thermodynamic cycles. The vast majority of combined cycles have as their secondary engine a Rankine or organic Rankine cycle steam turbine engine. Figure 1 shows that the Rankine cycle has its own losses of the concept of processes that form its cycle, not allowing a significant portion of energy to be converted into work. The Rankine and Organic Rankine cycle require changing the physical phase of the working gas, that is, there is a phase of the liquid process requiring condensing elements, evaporation and auxiliary pump systems, and all these elements and processes impose losses and impossibilities of utilize the energies of these phases in conversion. Some of the main advantages of the Brayton-isobaric-adiabatic combined cycle invention that can be seen are the absence of physical phase shift elements of the working fluid and its associated losses, the absence of condensation and vaporization elements, therefore no losses associated with latent heat of the working fluid, no circuits, pumps, control elements for the fluid phase change processes and their associated losses and consequently no volume, materials, mass and weight of the elements that make up such projects. Therefore, the innovation presented by the combined cycle Brayton with binary is expressive.

[017] Combined cycle turbine engines based on the integration of a Brayton cycle engine with a binary cycle engine may be constructed of materials and techniques similar to conventional combined cycle engines, as the secondary binary cycle unit consists of a Closed-loop gas engine, considering the complete system, this closed-loop working gas concept with respect to the external environment indicates that the system should be sealed, or in some cases leaks may be permitted provided they are compensated. Suitable materials for this technology should be noted, they are similar in this respect to Brayton external combustion cycle engine design technologies. The working gas depends on the project, its application and the parameters used, the gas may be various, each will provide specific characteristics, as the gases may be suggested: helium, hydrogen, nitrogen, dry air, neon, among others.
