项目摘要

Compared with the conventional combustion technology, in which the chemical energy is converted to heat, , the current study presents a new concept to extract and/or produce high quality of energies such as kinetic energy(power), photo energy(radiation) , the synthesis of valuable materials, and, even the feasibility of direct electric power and also at high rate of conversion through the combustion processes, not via thermal energy. The major results are summarized in the followings :1. Direct conversion to kinetic energy : Special considerations are focused on the power generations to accelerate the gas flow for the kinetic energy conversion through the isothermal combustion during the expansion processes. The basic analytical and some relevant experimental studies are carried out for aiming at the applications to the gas turbine as well as to the reciprocating engine. Some related study on energy analyses are executed to show the excellent characteristics of the proposed combustion … More scheme.2. Syntheses of valuable materials : The combustion is applied to produce the valuable materials as the combustion products, i.e. TiC heat-resisting material, hydrogen gas, etc. The reciprocating flow combustion methods in porous media are applied to show the prominent features for the drastic improvement for the energy saving. The experimental results indicate the conversion rate of methane in the direct steam reforming (partial combustion) up to 80 - 90% and also energy efficiencies to 85% even on the laboratory scale experiment and, in consequence, this method might be extended to the industrial technology.3. Conversion to photo (radiation) energy : Despite of the rather high conversion rate to the photo-energy compared with the existing technology in gas mantle combustion, the technical standard is still not high enough. Consequently, the new materials are necessary to be developed for higher conversion among the rare earth elements.4. Conversion to electric power : To begin with the feasibility study on direct energy conversion to the electric power, a preliminary experimental examination has been performed to reveal the flame structures of two different cases of extremely fuel-rich and lean combustion in some detail and lead to the better perspectives for a future technological development.

与将化学能转化为热量的传统燃烧技术相比，目前的研究提出了一种新的概念，以提取和/或产生高质量的能量，如动能（功率），光能（辐射），合成有价值的材料，甚至直接电力的可行性，并通过燃烧过程，而不是通过热能，以高转化率。主要研究结果如下：1.直接转换为动能：特别考虑的是发电，以加速气体流动，通过膨胀过程中的等温燃烧进行动能转换。本文针对在燃气涡轮机和往复式发动机上的应用进行了基础分析和相关的实验研究。通过能量分析，验证了该燃烧方式的优越性 ...更多信息方案2.有价材料的合成：利用燃烧生产有价材料作为燃烧产物，如TiC耐热材料、氢气等。多孔介质中往复流燃烧方法的应用显示出显著的节能效果。实验结果表明，直接蒸汽重整（部分燃烧）的甲烷转化率高达80 - 90%，即使在实验室规模的实验中，能量效率也高达85%，因此，该方法可以推广到工业技术.转换为光（辐射）能：尽管与现有的气体幔燃烧技术相比，光（辐射）能的转换率相当高，但技术标准还不够高。因此，为了提高稀土元素之间的转化率，需要开发新的材料.转换为电力：开始的可行性研究直接能源转换为电力，初步的实验研究已经完成，揭示了两种不同的情况下，极端富燃和贫燃燃烧的火焰结构的一些细节，并导致更好的前景，为未来的技术发展。少
