Background technique
Motor generally refers to heat engine, is a kind of by fuel, or other energy conversion heat energy that is working medium heat energy is further converted to a kind of device of mechanical energy output.
Along with socio-economic development, the mankind constantly increase power and electricity needs, but the exhausted and burning of fossil energy utilizes the environmental pollution that fossil energy causes to bring huge negative effect to society.Seek a kind of new efficient environmental-protection engine and can utilize various energy resources form such as gas, liquid, the many heat-source engines of many fuel of the solid form energy, renewable energy sources (solar energy, living beings, geothermal power etc.) are important means that solves at present energy source and power problem.
Internal-combustion engine is a kind of traditional, utilizes motor very widely.As its name suggests, internal-combustion engine is that a kind of fuel burns in cylinder interior, and modal is petrol engine and diesel engine.Because fuel combustion is carried out under the restrictive condition such as short time, intermittent type, cause fuel combustion insufficient, tail gas pollution is serious, off-design efficiency is poor, engine scuffing, and maintenance cost is high, high to fuel mass requirement, many shortcomings such as detonation and noise vibration.Internal-combustion engine is a kind of very ripe technology relatively at present, but its development is subject to certain limitation owing to being subject to above-mentioned disadvantages affect.
Outer heat engine is also a kind of ancient motor, and by external heat source, for engine interior working medium provides heat, the output of doing work after internal working medium absorption heat, if external heat source has burning to provide, also referred to as external-combustion engine.Common outer heat engine has Stirling engine.This motor is that the pastor Robert Stirling in London invented in 1816, is named as " Stirling engine " (Stirling engine).Stirling engine is unique heat engine, because their theoretic efficiency is no better than intrinsic peak efficiency (Carnot's cycle efficiency, Fig. 5 is the tephigram of Carnot's cycle, the efficiency upper limit of starting in theory function to reach, there is isentropic Compression process 1-2, decalescence process 2-3, isentropic expansion process 3-4 and isothermal exothermic process 4-1 composition).Fig. 3 is existing Stirling-electric hybrid structure principle chart.Fig. 4 is the tephigram of desirable Stirling-electric hybrid circulation, by isothermal exothermic process 1-2, waits and holds backheat exothermic process 2-3, and decalescence process 3-4, and wait and hold backheat endothermic process and form.Stirling-electric hybrid is a kind of outer thermo-motor, in the firing chamber of fuel outside working medium active chamber, burns continuously, by heat exchanger, heat is passed to the working medium of engine interior.Stirling circulation is a kind of closed cycle, can select working medium, hydrogen and helium etc. as internal working medium.
Outer heat engine is that with respect to outstanding advantages of internal-combustion engine it can utilize pluralities of fuel and various heating sources, and such as gas, liquid, solid fuel, the lower fuel ratio of calorific value is as biogas, living beings, complicated component fuels such as coal charcoal.Because outer heat engine can be utilized continuously, burning can, by full combustion of fuel, improve combustion efficiency for a long time, greatly reduces pollutant emission.Also utilize the thermals source such as solar energy, geothermal power, nuclear energy and some industrial waste heats, can also be used in some special devices, such as submarine and space power equipment etc.

As mentioned above, the burning of gas turbine is to carry out at engine interior, and products of combustion enters turbo machine, therefore from broadly also belonging to internal combustion engine, but due to its rotary movement, makes flowing continuously of air-flow, and then makes combustion process more complete.But because it still belongs to the mode of internal combustion, higher equally to the requirement of fuel.Therefore the concept of external heating gas turbine has been proposed very early.20th century the fifties, Donaid L. etc. is just studied coal-fired external heating gas turbine.The thermodynamic cycle process of external heating gas turbine: working medium is through compressor compresses, enter the hot device of high temperature heat exchange and fuel and carry out heat exchange at the high-temperature fuel gas of firing chamber discharge, after absorbing heat, become High Temperature High Pressure working medium, High Temperature High Pressure working medium enters the turbo machine acting of expanding, after expanding, pressure is barometric pressure substantially, the working medium of discharging from turbo machine enters firing chamber, burn with fuel mix, form high-temperature fuel gas, and enter high-temperature heat-exchanging, carry out heat exchange with the compression working medium of coming from compressor, heat is transferred to compression working medium, self reduces temperature, last waste gas is discharged.Its cycle specificity be working medium through overcompression, backheat, expand after just through burning, be a kind of thermodynamic cycle mode that utilizes tail part exhaust to burn again.Fig. 7 is the tephigram of existing external heating gas turbine cycle, has isentropic Compression process 1-2, isobaric heat absorption process 2-3, isentropic expansion process 3-4, and isobaric heating process 4-5 and isobaric exothermic process 5-1 composition.
Because the cycle specificity of gas turbine has determined there is the high thermal efficiency, working medium must be heated to very high-temperature, conventionally reach more than 1,000 degrees Celsius, therefore very high to the requirement of engine material, technique is more complicated.In addition after gas turbine design power diminishes (when as purposes such as automobile-used, distributed energies), due to reasons such as some flow losses increasings, makes its efficiency lower.
