Description

A kind of in-line arrangement thermal powerplant and work method thereof
Technical field
The invention belongs to thermal powerplant field, the thermal power transfer such as the high-temperature gas that the high-temperature gas, engine thermal energy or the tail gas that especially utilize solar energy, underground heat, combustible combustion to produce, factory discharge become the power machine of kinetic energy.
Background technique
Traditional power equipment has steamer, internal-combustion engine, external-combustion engine.
Steamer: be unable to do without boiler, whole device not only heaviness but also huge; The pressure and temperature of initial steam can not be too high, and exhaust pressure can not be too low, and the thermal efficiency is difficult to improve; It is a kind of reciprocator, and inertia limits the raising of rotating speed; Working procedure is discontinuous, and the flow of steam is restricted, and also just limits the raising of power.
Internal-combustion engine: complex structure, higher to demanded fuel, strict to the purity requirements of fuel, environmental pollution.
External-combustion engine, if Stirling engine is wherein a kind of, Stirling engine compares with internal-combustion engine and possesses following advantage:
Be applicable to the various energy, no matter be liquid, gaseous state or solid-state fuel, when adopting heat-carrying system (as heat pipe) indirect heating, almost can use any high temperature heat source (solar energy radioisotope and nuclear reaction etc.), and motor itself (except heater) does not need to do any change.Stirling engine is without the need to compressor boost simultaneously, uses general blower fan to meet the demands, and allows fuel to have higher impurity content; Stirling engine single-machine capacity is little, unit capacity from 20-50kw, the increase and decrease power system capacity that can suit measures to local conditions; Structure is simple, number of components fewer than internal-combustion engine 40%, and room for price-cut is large; Maintenance cost is low.
Stirling engine operationally, due to continuous burning in the firing chamber of fuel outside cylinder, working medium independent of combustion gas is absorbed heat by heater, and externally do work by Stirling cycle, therefore avoid pinking acting and the intermittent combustion process of similar internal-combustion engine, thus achieve efficient, low noise and low emission runs.Efficient: overall energetic efficiency reaches more than 80%; Low noise: in 68dBA at the bottom of 1 meter of bare machine noise; Low emission: exhaust emissions reaches Europe 5 standard.
Because working medium is not burnt, external-combustion engine avoids the quick-fried acting problem of shake of traditional combustion engine, thus achieves high efficiency, low noise, low stain and low operating cost.External-combustion engine can burn various inflammable gas, and as rock gas, biogas, petroleum gas, hydrogen, coal gas etc., the also liquid fuel such as incendivity diesel oil, liquefied petroleum gas (LPG), can also burn wood, and utilizes solar energy etc.As long as hot chamber reaches 700 DEG C, equipment can do work operation, and ambient temperature is lower, and generating efficiency is higher.The maximum advantage of external-combustion engine to be exerted oneself and efficiency does not affect by altitude, is very suitable for high altitude localities use.
Simultaneously Stirling engine remain subject matter and shortcoming be: manufacture cost is higher, and working medium sealing technique is more difficult, and reliability and the life-span of Sealing also have problems, and cost of material is high, and power adjustments control system is more complicated, and machine is comparatively heavy; The cost of expansion chamber, pressing chamber, heater, cooling chamber, regenerator etc. is high, and heat loss is 2-3 times of explosive motor etc.
Organic rankine cycle system comprises pump, vaporizer, decompressor, generator, condenser etc.Heat collector absorbs solar irradiance, and in heat collector, heat exchange medium temperature raises, and heat transferring medium passes to organic working medium by vaporizer heat.Organic working medium is level pressure heating in vaporizer, and the gaseous state organic working medium of high pressure enters expander acting, and drive electrical generators generates electricity; The organic working medium that decompressor afterbody is discharged enters level pressure condensation in condenser, and the organic working medium of condensator outlet enters vaporizer and completes a power generation cycle after pump pressurization.
It is not high to there is conversion efficiency in organic rankine cycle system, and volume is large, needs to do work by baroque decompressor.
In line engine compact dimensions, stability is high, and low-speed torque characteristic is good and fuel consumption is also less, and resultant is that manufacture cost is also lower, adopts the motor volume of cylinder in line layout also compact simultaneously, can adapt to layout more flexibly.Also the device arranging pressurized machine class is convenient to.Major defect is that the power of motor itself is lower, and is not suitable for the automobile of more than outfit 6 cylinder.
Summary of the invention
The cost that instant invention overcomes the expansion chamber of existence, pressing chamber, heater, cooling chamber, regenerator etc. is high, and heat loss is the problems such as 2-3 times of explosive motor; Overcome organic rankine cycle system and need decompressor or steam turbine, the technical barrier that manufacture cost is high; Overcome the problem that internal-combustion engine pancake engine structure is comparatively complicated, machine oil easily leaks, manufacture cost is high.The in-line arrangement thermal powerplant that the present invention proposes utilizes existing in line engine structure, in conjunction with the thermodynamic apparatus of Stirling engine, organic rankine cycle system and internal-combustion engine in line engine advantage.After heat absorption, gasification reactor is heated by heat collector, make the swollen promotion piston of working medium high-temperature gasification Peng produce kinetic energy acting.
The invention provides that a kind of thermal energy conversion efficiency is high, working medium can recycle, working medium quantity can be adjusted to adjust output power, to carry out adjusting the thermal powerplant of output power, machine stable output power by adjustment temperature within the scope of peak output.
