Description
Technical field
The utility model relates to LNG fuels and energy technical field of ships, especially a kind of novel LNG ship oceangoing ship power plant system.
Background technique
LNG Liquefied natural gas (LNG) main component is methane, colourless, tasteless, the nontoxic and non-corrosiveness of LNG, and as the energy of a kind of economy, green, environmental protection, safety, advantage is given prominence to.Shipping progressively adopts LNG as fuels and energy, is just becoming the developing direction that shipbuilding industry is new.International Maritime Organization (IMO) control to marine engine toxic emission is more and more stricter, to on January 1st, 2016, IMO Tier III emission standard will come into force, this means that the motor that the boats and ships of henceforth navigation in emission control district (ECA) are installed must meet this standard in toxic emission, therefore LNG becomes first-selected as the fuel of ship power.Since entering 21 century, along with the date of petroleum resources in world wide is exhausted, rock gas just progressively replaces the energy pattern that oil becomes main in world wide.LNG is as the relatively traditional fuel oil rich reserves of a kind of emerging energy and environmental advantage is obvious, other emerging energies such as relative solar energy and fuel cell, the advantage highly significant of LNG in Economy.LNG peculiar to vessel mainly contains single use LNG fuel and uses duel fuel engine two profiles formula.From the ship type researched and developed both at home and abroad at present, LNG cargo ship generally adopts single LNG as the energy of mainly advancing by leaps and bounds, but not LNG cargo ship adopts duel fuel engine mostly.But boats and ships directly use LNG easily to occur that burning is insufficient as fuel, the problem that energy utilization rate is low.
Model utility content
LNG is directly used easily to occur that burning is insufficient as fuel in order to solve boats and ships, the problem that energy utilization rate is low, the utility model provides a kind of novel LNG ship oceangoing ship power plant system, first by LNG cracking in chemical heat regenerator, and then be transported to Ship Power Equipment burning and provide power for boats and ships, improve the utilization ratio of LNG gas on the one hand, also improve the power performance of LNG ship oceangoing ship.
The utility model solves the technological scheme that its technical problem adopts: a kind of novel LNG ship oceangoing ship power plant system, comprise: LNG storage tank, plate type heat exchanger, chemical heat regenerator, steam generator and Ship Power Equipment, LNG in described LNG storage tank by pipeline through plate type heat exchanger to chemical heat regenerator, NG in chemical heat regenerator cracking under steam generator provides the condition of water vapour, described chemical heat regenerator by LNG cracking gas by Pipeline transport to Ship Power Equipment for ship power provides fuel.
Further, also comprise for reclaiming the exhaust gas heat exchanger of LNG cracking gas at Ship Power Equipment calory burning.
Particularly, described exhaust gas heat exchanger is used for providing heat to chemical heat regenerator.
Particularly, described exhaust gas heat exchanger is used for providing heat to steam generator.
The beneficial effects of the utility model are: the one that the utility model provides novel LNG ship oceangoing ship power plant system, first by LNG cracking in chemical heat regenerator, and then be transported to Ship Power Equipment burning and provide power for boats and ships, improve the utilization ratio of LNG gas on the one hand, also improve the power performance of LNG ship oceangoing ship, the cracking gas of CH4 improves 206.4KJ/mol than the chemical energy of the CH4 of coordinate quality, methane is endothermic pyrolysis before entering firing chamber, generates CO, H
2, this process causes fuel grade to reduce, and thus reduces chemistry in combustion process
to physics
transform
loss; The application of exhaust gas heat exchanger, has reclaimed Ship Power Equipment waste heat, and uses it for chemical heat regenerator and/or steam generator heat supply, improves the comprehensive utilization ratio of LNG.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
In figure: 1.LNG storage tank, 2. plate type heat exchanger, 3. chemical heat regenerator, 4. steam generator, 5. Ship Power Equipment, 6. exhaust gas heat exchanger.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of novel LNG ship oceangoing ship power plant system, comprise: LNG storage tank 1, plate type heat exchanger 2, chemical heat regenerator 3, steam generator 4 and Ship Power Equipment 5, LNG in LNG storage tank 1 by pipeline through plate type heat exchanger 2 to chemical heat regenerator 3, NG in chemical heat regenerator 3 cracking under steam generator 4 provides the condition of water vapour, chemical heat regenerator 3 by LNG cracking gas by Pipeline transport to Ship Power Equipment 5 for ship power provides fuel.
Specifically, this novel LNG ship oceangoing ship power plant system also comprises for reclaiming the exhaust gas heat exchanger 6 of LNG cracking gas at Ship Power Equipment 5 calory burning, and exhaust gas heat exchanger 6 provides heat for giving chemical heat regenerator 3 and steam generator 4.
Specifically, the heat of chemical heat regenerator 3 is by the small part NG combustion heat supplying in plate type heat exchanger 2.
Its working principle is: theoretical foundation is CH
4the main chemical reactions occurred in chemical heat regenerator is as follows:
Steam reforming reaction:
Δ H
298K=206.4KJ/mol
Partial oxidation reaction:
Δ H
298K=-36.0KJ/mol
CO2 reforming reaction:
Δ H
298K=247.0KJ/mol
Autothermal catalysis is reformed:
Methane cracking reacts:
Δ H
298K=74.8KJ/mol
Water-gas shift reaction:
Δ H
298K=-41.0KJ/mol
The NG of LNG after plate type heat exchanger 2 is vaporized is cracked into CO, H in chemical heat regenerator 3
2, water conservancy used heat is vaporized, and portion of methane incendivity eliminates the lower defect making methane cracking conversion ratio on the low side of taste because of waste gas residual heat temperature to chemical heat regenerator 3 heat supply.With vaporized LNG for ship power power plant provide fuel, using waste heat from tail gas conversely cracking methane is (main
), allow NG cracking gas (main CO and H2) replace NG to provide fuel for ship power power plant.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
