Abstract

The present invention relates to a novel electric power electric drive device which uses high-temperature and high-pressure fuel gas generated by the combustion of liquid fuel or gas fuel in limited space for vaporization, simultaneously, water entering a combustion chamber is made to form high pressure steam injected from a nozzle, and the high pressure steam is directly input to a turbine generator for doing work. The present invention has the obvious characteristics of no atmospheric pollution, heat transfer without media, simple and compact structure, rapid startup and high safety. The novel electric power electric drive device can be used for generating electricity, and can be used for providing power to large devices of other corresponding stationary situations by steam.

Description

Internal combustion steam generator

The present invention is the water that a kind of the high-temperature high-pressure fuel gas vaporization that utilizes liquid or gaseous fuel to produce in confined space internal combustion enters the combustion chamber simultaneously, forms high steam and sprays with jet pipe, directly imports the novel electric power power set of steam turbine generator work done.

Existing heating power power set, what have utilizes the fuel combustion expansion working, as gasoline engine, diesel engine, gas-turbine unit etc., the 〈 ﹠﹠ that has〉can produce steam by boiler, input steam engine, vapor wheel 〈 ﹠﹠ 〉.They can utilize aspect, internal combustion engine has only utilized fuel 〈 ﹠﹠〉the crunch work done that produces of limit space internal combustion, and do not have 〈 ﹠﹠ use heat energy, and fuel time of staying in the combustion chamber is of short duration, it is very incomplete to burn; The boiler plant of steam is provided for steam engine, steam turbine, the heat energy that has only utilized fuel combustion to produce, and do not utilize the crunch potential energy that it produces in combustion process, and equipment is huge, and need strict water treatment, more than hot machine also have a common shortcoming, be exactly atmosphere pollution, and the thermal efficiency is low, and other hot machine also has similar disadvantage.

Task of the present invention is: break the outmoded notion of " not mixing like water and fire ", change the traditional approach that conducts heat by medium, concentrate the advantage of internal combustion engine and steam boiler, internal combustion and vaporization are carried out simultaneously.

The present invention is a kind of internal combustion steam generator as shown in the figure, mainly formed by jet pipe (1), stack shell (2), top cover (3), wherein in the spray chamber of top cover (3) top atomizer (4) is arranged, there is the (operating) water nozzle (7) of spark plug (5), fire-fighting mouth (6) and water-dividing chamber pass-out at the middle part, and combustion gas eddy current kuppe (8) is arranged at the bottom.

Technical solution of the present invention is: in spray chamber, utilize the direction of rotation of fuel and combustion air different, make its uniform atomizing or mixing; In the combustion chamber, utilize the appropriate oblique angle of fuel nozzle, in combustion gas eddy current kuppe, form eddy current type combustion centre, make fuel completing combustion under the condition of high temperature, high pressure and fully oxygen supply; In vaporization zone, utilize the eddy current direction of rotation difference of combustion G﹠W, form the random motion of combustion gas and steam, quicken the vaporization of water; At whole steam generator inwall, utilize the moisture film of the high-speed screw motion formation of water under high pressure that high-temperature fuel gas is all surrounded, the heat that the combustion centre position is distributed all is pressed into moving water.Because what contact with the steam generator inwall mainly is water, temperature is not high, and auxilliary outside and heat preserving and insulating material can drop to bottom line with its heat loss, increases substantially the thermal efficiency.

Distinguishing feature of the present invention is:

One, there is not atmosphere pollution.Because of fuel in the steam generator internal-combustion, combustion gas directly mixes with water and produces steam, after the work done of input steam turbine, steam reduction Cheng Shui, and other combustion product is soluble in water, water through processing accordingly after, promptly reusable.

Two, do not conduct heat by medium, need not too strict water treatment, and be not subjected to the influence of heat-transfer matcrial thermal conductivity factor, so can increase substantially the thermal efficiency.

Three, simple in structure, compact, start rapidly, be convenient to maintenance.

Four, have good security performance,, do not have incrustation scale to form, be difficult for having an accident because of steam is in high-speed motion state.

Accompanying drawing is the internal combustion steam generator sketch, and wherein the A-A section is an atomizer, and the B-B section is the fire-fighting mouth, and the C-C section is a (operating) water nozzle.

This device steam generation process is as follows:

The water of six (operating) water nozzles is supplied with by high-pressure hydraulic pump in the steam generator, because nozzle all is close to the generator inwall in same direction, and an oblique angle arranged, so the water of high pressure ejection all is close to the inwall curl and is advanced, again because action of centrifugal force, make the water formation moisture film that scatters, so both can increase heating surface area, can reduce the loss of heat again, also heat time heating time can be prolonged, and, also can produce certain heat and acceleration absorption for position institute of combustion centre distribute heat because the high speed circular motion of water makes water generates acutely rub, roll, collide.The fuel of fuel nozzle in the combustion chamber, supply with by petrolift, combustion air is supplied with by air compressor or high pressure blower, fuel adopts the vortex generator of different directions to make it uniform atomizing in apex cavity with combustion air or mixes, be pressed into combustion chambers burn again, the combustion gas of six nozzles on every side is along the imaginary circle tangential direction ejection that is equivalent to two times of diameters of steam (vapor) outlet, after spark ignitor, in combustion gas eddy current kuppe, form combustion centre, the combustion gas eddy current is opposite with water (flow) direction, the formation of combustion gas eddy current can prolong the burning time of combustion gas in kuppe, also can produce certain centrifugal force, make combustion gas after breaking away from kuppe, press to moving water on every side, thereby all heats all will fully contact it by the steam of positive and negative eddy current mixing back formation and the random motion of combustion gas under the eddy current action of centrifugal force, can allow the water that is not vaporized fully accept heat energy on dried up of the water band that has been vaporized.Because temperature difference, vapour density are also different, so the good inevitable rotation direction of the steam central authorities of vaporization, at this moment the combustion gas of top of combustion chamber nozzle is heated once more to it, because the heat absorption capacity of steam is extremely strong, thereby the high temperature of combustion gas all is absorbed, form superheated steam, spray by steam (vapor) outlet.

Implement the present invention, as long as there is the factory of certain boiler for producing experience and tester all can produce, specification requirement is also roughly the same with the production boiler, just combustion gas eddy current kuppe, the most handy oxida-tion-resistant steel manufacturing, other position require have enough intensity and good sealing property to get final product.

The present invention preferably and the supporting use of steam turbine generator, but the relatively large equipment that also can be used for other relative fixed occasion provides power with steam.
