使燃烧

In other words, the results novelty broke the conclusion in the pervious reports that combustion synthesis can't occur once Fe content in Fe-Ti-C system is more than 60wt%, and gave more engineering meaning to combustion synthesis of iron-based composites.

而这正是本研究的创新点之一，即打破了前人研究所得出的"Fe-Ti-C体系中Fe含量超过60wt％就不能实现燃烧合成"的界限，从而使Fe-Ti-C体系燃烧合成制各铁基复合材料更具有工程意义。

Firstly, the two parts are solved separately, and the results are then coupled together. Because the thickness of the combustion reaction zone at high Re and Da numbers is less than the turbulent diffusion scale in diesel engines, the flame is extremely thin, its micro-structure keeps the laminar structure, so the turbulent flame can be regard as the ensemble of locally one dimensional, thin laminar flamelet embedded within the turbulent flow field.

由于柴油机中在高雷诺数和高Damkoeler数的情况下，燃烧反应区厚度小于湍流耗散尺度，火焰极薄，其微元保持层流结构，因此，湍流火焰可视为嵌入湍流流场内局部具有一维结构的薄的层流小火焰的系综，这便构成了层流小火焰模型主导思想，同时也使层流小火焰模型模拟柴油机湍流燃烧过程成为可能。

The invention is capable of increasing the air pressure in the air inlet manifold and improving the aeration coefficient in the cylinder while in instantaneous acceleration, thereby changing the combustion conditions of the internal combustion engine at a medium and low speed, resolving the problem of the poor accelerating performance of the turbocharger at the medium and low speed, improving the output torque at the medium and low speed, optimizing the accelerating performance and greatly shortening the acceleration response time of the automobile; moreover, because the fuel is fully burned, the utilization factor of the fuel is also improved and the discharge capacity of the internal combustion engine is reduced.

本发明能够增加进气歧管内的空气压力，提高加速瞬时缸内的充气系数，从而改变内燃机中低速的燃烧状况，并改变涡轮增压机中低速加速性能差的问题，提高中低速的输出扭矩，优化加速性能，使车辆的加速响应时间大大减短；同时，由于燃料获得了充分燃烧，也提高了燃料的利用率，降低了内燃机的排放量。

A new desulfurization apprach for pulverized coal combustion is introduced in this paper; pulverized coal is first burn in a precombustion furnace under oxygen deficient condition (about 30% air needed in boiler is provided for precombustion), in precombustion moust of sulfur in coal is decomposed and oxidized, and evolved, the sulfur evolved is trapped in a desulfurizing fluidized bed by calsuim, and then the char and gas are introduced to the boiler furnace for complete combustion.

本文提出了一种煤粉燃烧脱硫新方案，利用煤中硫优先氧化分解释出的原理，用少量的空气（大略为锅炉实际空气用量的30％），在一前置燃烧室中，使煤粉中硫的绝大部分被分解氧化，释放出来，释放出来的硫在脱硫流化床中被石灰脱硫剂脱除，未燃烧的炭粒与烟气再吹进锅炉膛中完全燃烧。

This process organically combines the circulating fluidized bed combustion technology with boiler-front low-temperature dry distillation technology, the hot ash of circulating fluidized bed is used as the hot carrier to pyrolyze the coal and generate tar and gas. The semi-coke after pyrolysis is fed into boiler to generate steam for power generation and heat supply. The total energetic efficiency of this process is 10% higher than the single power generation process.

中科院山西煤化所开发的煤炭干馏-循环流化床燃烧多联产技术，是将循环流化床燃烧技术与炉前低温干馏技术有机地结合起来，用循环流化床锅炉的高温循环热灰作为载热体使煤发生热解，产生焦油和煤气，热解后的半焦作为锅炉燃料送入炉内燃烧以生产蒸汽，用来发电和供热，多联供集成系统比单纯发电系统的总能效率提高约10％。

The conducting wall in micro-tube preheats the inlet mixture by axial heat transfer. The existence of conducting wall will help to reach full reaction in the micro-tube. As the inlet velocity increases, both the existence of the surface catalytic combustion and the gas phase combustion become the limiting factors on combustion. Wall material and equivalence ratio of hydrogen/air mixture have important influence on catalytic combustion of hydrogen.
