Abstract
Description
[0001] HIGH EFFICIENCY POWER MACHINE
[0002] Technical Field
[0003] The invention relates to a high-efficiency power machine in connection with the thermodynamic field, such as a steam power plant, using liquid oxygen as the fluid, hydrogen as the combustor and demineralised water as the coolant.
[0004] Prior Art
[0005] Technically, water and water vapour are used in steam power plants. Steam power plants also have boilers. Various fuels such as LPG, diesel, fuel oil, natural gas and nuclear fuel etc. are used in these boilers. Some of these plants operate according to the supercritical Rankine cycle. In steam power plants in these closed systems, liquid and steam are heated and cooled at constant pressure.
[0006] In pumps the fluid is isoentropically compressed, in turbines and compressors it is isoentropically expanded and compressed. The fluid expands isoentropically. Differences in kinetic and potential energy are neglected and heat transfer in the heat exchanger takes place at constant pressure. Continuous process conditions apply and heat loss in the heat exchanger, tanks, combustion chamber and turbine is negligibly isolated.
[0007] In order to obtain the actual cycle of steam engines, the friction losses and heat losses at various points and the difference required for heat transfer in the heaters must be taken into account.
[0008] US11852044B2 discloses a steam power plant-like power machine system that can be used both stationary and mobile, using a mixture of liquid nitrogen and / or liquid air as a fluid and atmospheric air as an energy source.
[0009] When the existing studies in the art are examined, the need for the development of a high efficiency power machine related to the thermodynamic field similar to a steam power plant using liquid oxygen as the fluid, hydrogen as the combustor and demineralised water as the coolant was obtained.
[0010] Objectives of the Invention
[0011] The object of the present invention is to develop a high-efficiency power machine in connection with the thermodynamic field, such as a steam power plant, using liquid oxygen as the fluid, hydrogen as the combustor and demineralised water as the coolant.
[0012] Another object of the present invention is to develop a high-efficiency power machine in which the output temperature of the recuperator is maintained at a constant temperature in summer and winter.
[0013] Another object of the present invention is to develop a high efficiency power machine which can be produced at a lower cost than the machines available in the art for obtaining and utilising hydrogen and oxygen from a water source.
[0014] Another object of the present invention is to develop a high efficiency power machine in which ordinary water is discharged as exhaust.

[0033] The invention relates to a high-efficiency power machine using liquid oxygen as the fluid, hydrogen as the combustor and demineralised water as the coolant, comprising,
[0034] Tank 1 (1) containing liquid oxygen,
[0035] Pump (2) connected to tank I (1) for pressurising the liquid oxygen taken from tank 1 (1),
[0036] Recuperator (3) connected to the pump (2) and heating the liquid oxygen leaving the pump (2),
[0037] Tank II (5) containing hydrogen gas,
[0038] Tank III (6) containing water,
[0039] Combustion chamber (4) where the hydrogen from tank II (5) is combusted with oxygen gas from the recuperator (3),
[0040] Turbine (7) connected to the combustion chamber (4) and generating work with the liquid vapour from the combustion chamber (4),
[0041] Alternator (8) connected to the turbine (7) and generating alternating current with the work received from the turbine (7).
[0042] In the inventive power machine, the first starting tube (13) is used to generate the initial energy required for the operation of the power machine. The power machine consists of valves (12) for controlling the amount of fluid, positioned on the outlet lines of the pump (2), tank I (1), tank II (5), tank III (6) and the first starting tube (13) and on the inlet lines of the recuperator (3), combustion chamber (4) and turbine (7).
[0043] In the combustion chamber (4) of the inventive high efficiency power machine, there are platinum and palladium spark plugs for combustion of oxygen with hydrogen.
[0044] The inventive power machine has a two-cycle structure. In the first cycle, firstly, the liquid oxygen in tank I (1) is sucked with a pressure of approximately 10.0 MPa with the help of pump (2) and sent into the recuperator (3) by increasing the pressure. The cold liquid oxygen coming from the pump (2) is heated up to the oxygen critical pressure (5.08 MPa) and critical temperature (154.581 K) in the recuperator (3) and delivered to the combustion chamber (4) as gas. Oxygen gas enters the combustion chamber (4) from the recuperator (3) as fully vaporised superheated gas. After the superheated oxygen gas is introduced into the combustion chamber (4), the hydrogen gas in tank II (5) is introduced into the combustion chamber (4) and the combustion reaction is carried out in the combustion chamber (4). The pressure of hydrogen gas is approximately 15 MPa. Meanwhile, in order to control the temperature of the combustion chamber (4), the water in tank III (6) is fed into the combustion chamber (4) in a controlled manner and the temperature of the combustion chamber (4) is kept under control. The water taken from tank III (6) is pulverised with an injector and sprayed in the direction of flow to ensure an ideal combustion.
[0045] Normally, the adiabatic flame temperature of hydrogen is 2318 K. Since the strength of the objects cannot withstand this temperature, this flame temperature must be reduced. In this case, the heating of oxygen, hydrogen and water entering the combustion chamber (4) from the initial values to the flame temperature will determine the flame temperature. In fact, approximately 15 MPa demineralised water can be used (sprayed) to obtain a comfortable temperature from the initial values to the flame temperature. After the reaction, the output of the combustion chamber (4) will be completely water vapour. The superheated water vapour thus obtained is sent to the turbine (7). Thanks to the superheated water vapour, the turbine (7) will rotate and a work will be produced. The work obtained will enable energy to be obtained with the help of the alternator (8) connected to the turbine (7).
[0046] The outlet pressure of turbine (7) is approximately 0.101325 MPa. The inlet enthalpy of turbine (7) can be calculated with the help of formula I. hToutput=hliquid+x(h steam" hiiquid) (Formula I) x=0,87 will be determined according to the degree of dryness. x, if the degree of dryness is greater than 0.87, water droplets can damage the blades by impacting the turbine (7) rotor blades.
[0047] In the example application of the inventive power machine, the exhaust from the turbine (7) enters the recuperator (3), where it will help to heat the liquid oxygen coming from the pump (2) with a temperature of about 100 °C and a pressure of 0.101325 MPa. The water from the recuperator (3) is transmitted to the heat exchanger (10) and the water vapour liquefies at the outlet of the heat exchanger (10) and is discharged by taking water from the exhaust. The ambient air passing through the heat exchanger (10) with the fan (9) exits at +22 °C and enters the cabin (11). Thus, as long as the power machine is operated in the cabin (11), +22 °C is always maintained. This energy consumption in heating and air conditioning in mobile machines is accepted as approximately 10%. Here, the cabin (11) refers to the inside of the vehicle (car, aircraft, etc.) in which the power machine is used. This situation can be considered as the utilisation of the waste of the power machine.
[0048] The inventive power machine operates with an efficiency of over %70.
[0049] In the alternative application of the inventive power machine in petrol and diesel machines, the alternator (8) can be removed and the steam turbine (7) shaft can be connected to the gearbox input.
