The invention relates to a processing method of preventing frostbite and restarting of hydrogen electric pile, whose characteristic lies in the treating processes includes: When the electric pile turns off, the unsaturated fuel gas or the nitrogen, through the circle boast to clean the dissociate water; drying the MEA film module to keep the water content below the stipulated temperature which does not ice up; then the recycle gas through a wet exchanger to dry and the dried gas is continue used in the dry pile step; when restarting the electric pile, the recycle gas must heats then through the pile to elevate the temperature, then heats the fuel gas and the oxidant of the gas source, through the weting of the wet exchanger enters to the calefactive pile, enhances the wet step of the film module in the pile, starts the power output of the pile.

本发明涉及一种氢电堆的防冻和重新启动时的处理方法，其特征在于处理过程包括：电堆停机时，将水蒸气不饱和的燃料气体或氮气，通过循环吹扫除去电堆的游离水；干燥其中的MEA膜组件，使膜组件含水量降低到规定低温下不结冰的程度；而后再令循环气体通过一个湿交换机将循环气体干燥，以及被干燥后的循环气体继续用来干燥电堆的步骤；在电堆重新启动时，须将循环气体加热后通过电堆，使电堆升温，然后再将气源的燃料气及氧化剂加热，通过湿交换机加湿后进入已升温的电堆，提高电堆中膜组件的湿度的步骤，开始电堆的功率输出。

The invention is characterised in that the gaseous fuel containing hydrogen or consisting of hydrogen is fed into the swirl generator (1) largely axially and/or coaxially to the burner axis, forming a fuel flow, with a largely spatially defined flow form (9) which is maintained inside the burner and opens up in the region of the burner outlet.

本发明的特征在于，所述含有氢气或者由氢气所组成的气态燃料在涡流发生器(1)内相对于燃烧器轴线尽可能轴向地和/或同轴地、在形成燃料流的情况下以尽可能空间受限制的流动形状(9)被输入，该流动形状(9)在燃烧器内得以保持，并且在燃烧器出口的范围内绽开。

Clean energy economy will lead to higher consumption per capita than harmful energy economy when CER value is high enough and the cumulative net capacity is zero. On the contrary, clean energy economy will lead to lower consumption per capita than harmful energy economy when CER value is not high enough, which means it is not able to counterweigh the cost of ethanol, or when ethanol production efficiency is low enough.

3当CER价值足够高而净资本累积为零时，洁净能源体系会较污染性能源经济体系造成较高之人均消费；反之若CER价值不够高，亦即不足以弥补燃料酒精生产成本时，或者燃料酒精生产效率足够低，则可能获得较低的长期人均消费水准。

The industry of biomass fuel ethanol is in the cubhood. The quantitative research with enterprise practice on circulatory economy conception is insufficiency at present. The study on energy income of biomass fuel ethanol has not got creditable explanation.

我国的生物质燃料乙醇产业还属于幼稚产业，目前对该产业的基于循环经济理念的企业实践的定量研究还很不足，对生物质燃料乙醇能量收益的研究也还没有给出令人信服的解释。

The experimental results indicated that under the steady operating conditions, the ignition timing of the base fuel (PRF90-90% iso-octane+10% n- heptane), which is equivalent to RON 90, delayed and the peak value of the heat release rate was low compared to the base fuel with single additive (Ditert-butyl peroxide-DTBP, Dicumyl peroxide-DCP, Tert-butyl hydroperoxide-TBHP, Tert-butyl cumyl peroxide -TBCP or Cumene hydroperoxide-CPO) which advanced ignition timing and increased the peak of the heat release rate obviously.

试验结果分析表明，在HCCI发动机燃烧稳定工况下，没有添加剂的基础燃料记作PRF90(为90%异辛烷与10%正庚烷的混合，相当于90号汽油)着火滞后，燃烧放热率峰值低，而混有单一添加剂(Ditert-butyl peroxide-DTBP、Dicumyl peroxide-DCP、Tert-butyl hydroperoxide-TBHP、Tert-butyl cumyl peroxide-TBCP或Cumene hydroperoxide-CPO)的基础燃料则着火明显提前，燃烧放热峰值升高。

An analytical model was presented to study the cloud expansion during near field regime, and the liquid fuel expanding velocity-radius relation and the liquid breakup model were given. A 2-dimensional axisymmetrical diphasic flow numerical simulation for cloud expansion during far-field regime was carried out, and the distribution parameters of fuel in cloud were given.

Thereby, amount of air larger than amount of fuel can be provided, hydric gas activated as fuel and oxide-containing gas which is corresponded to the hydric gas with an appropriate or optimal proportion can be provided.

因此，可提供大于燃料量的空气量，而以合适的或最佳的比例提供作为燃料的氢气和与此相应的含氧空气。

Meantime, in order to value the ignition ability, an experiment to ignite the liquid and gas fuel with plasma ignitor was applied. From the results, this dissertation concluded the ignition boundary about the plasma ignitor.

同时，为了进一步考察等离子点火器的点火性能，作者在等离子点火器试验台上进行了液体燃料和气体燃料的等离子点火试验，考察了该型等离子点火器的点火边界和工作性能。

When diesel/CNG dual-fuel turbocharge intercooling engine D6114 runs in dual-fuel mode, only diesel fuel is supplied when starting and idling, and when engine speed is beyond the preset value,electronic control system send out command to limit diesel fuel injection amount,and natural gas begin to enter into cylinder through mixer to take part in burning, at this time small a mount of diesel fuel shall play mainly a role of ignition,and engine load is changed by altering natural gas supply amount.

D6114柴油/CNG双燃料增压中冷发动机当以双燃料方式工作时，发动机起动和怠速只燃用柴油；当转速超过某设定值，电控系统发出指令限制柴油的喷油量，天然气经混合器进入气缸参与燃烧，此时少量柴油供给主要起引燃作用，发动机负荷变化则通过改变天然气供给量的大小来实现。
