第一篇:华北电力大学热能与动力工程专业英语课堂作业翻译
1.如图1-1(a)所示,由活塞和气缸组成的装置中装有1kg水。假定活塞和其上的重物使气缸内压强维持在0.1Mpa,初始温度20℃。当有热量开始传递给水时,缸内水温迅速上升,而比容略有增加,气缸内压强保持恒定不变。当水温达到99.6℃时,如若再增加传热量,水将发生相变,如图1-1(b)所示。也就是说,一部分水开始气化变为蒸汽,在此相变过程中,温度和压强始终保持不变,但比容却有大幅度的增加。当最后一滴液体被气化时,进一步的加热将使蒸汽温度和比容均有所增加,如同1-1(c)所示。
现代660MW燃煤锅炉有大约6000吨的压力部件,包括500千米的受热面管材,3.5千米连接管与联箱和30000个管接头焊口。
这是经过大约50年发展的结果,并形成了煤粉在具有蒸发管束的炉膛燃烧,烟气然后流经对流过热器和热回收表面的基本概念并保留至今。蒸汽参数的提高,机组容量的增大及燃料燃烧特性的改进都要求在材料、制造技术和运行程序上相应发展。
所有大型汽轮发电机转子在制造时,都规定要做耐超速20%试验。这样在转子的运行转速范围内,能够保证很好的转子平衡。从而在由电网系统扰动引起的正常超速和超速螺栓试验中经常的10%超速中,能有足够的余度。另外对转子进行超速试验还能验证锻件,因为在超速运行时,转子的离心应力要大于常规运行中的离心应力,由此为衡量防止转子自发快速断裂的裕度提供了定量手段
凝汽器是一个大型表面式换热器,进入凝汽器的蒸汽被凝结,从附近的河或湖中抽取的循环水将所产生的潜热带走。循环水由电动或汽动循环水泵泵入凝汽器。因为进入凝汽器蒸汽的流量极大,不可避免的会有一定比例的气体不发生凝结。为了在凝汽器中建立并保持一个非常接近真空状态的负压,必须从凝汽器壳体中去除这些“不凝结气体”。通常通过射汽抽气器去除这些气体,它的主要组成是一个喷嘴,蒸汽通过喷嘴获得很高的流速,从而带走那些不凝结的的气体。然后流经喷嘴的蒸汽(作为原动力的蒸汽)和被其机械携带的不凝结气体进入通常被称作二次凝汽器的换热装置,蒸汽在环境压力下凝结,不凝结气体被排入大气。射汽抽气器置于一个或两个级内,本质上是一台压缩机,它将不凝结蒸气的压力从几乎完全真空提高到大气压来清除掉。
5.如图5-6所示的三冲量就是汽包水位蒸汽流量和给水流量。该系统中基本的控制是依据蒸汽流量和给水量之间的关系。该闭环系统中在正常的稳定状态下汽包水位处于恰当值此时蒸汽流量和给水流量之比为11。该条件的仸何变化都将产生一施加在给水控制阀上的控制信号液位信号也会引起给水阀的重新调整仍而把液位信号调整回期望值。控制系统中的给水流量测量信号用于决定给水管路中调节阀的开度仍而使得流入的给水量和锅炉的蒸汽输出量相等。因此调节阀前给水压力的仸何变化所导致的给水流量变化将由流量计立刻检测出来调节阀将起作用。
第二篇:热能与动力工程专业英语
强度量:intensive properties do not depend on mass(e,g,p,ρ,ν=1/ρ,u and h),extensive properties depend on the total mass of the system(e,g,V,M,U,and H).Uppercase letters are usually used for extensive properties.准平衡:equilibrium:states of a system are most conveniently described when the system is in equilibrium, i.e.it is in steady-state.Often we will consider process thatchange “slowly”-termed quasi-equilibrium or quasi-static process.A process is quasi-equilibrium if the time rate of change of the process is slow relative to the time it takes for the system to reach thermodynamic equilibrium.It is necessary that a system be quasi-equilibrium before applying many of the thermodynamics relations to that system.热力学第一二定律:In simplest terms,the law of thermodynamics dictate the specific for the movement of heat andwork.Basically,the First Law of Thermodynamic is a statement of the conservation of energy-the Second Law is a statement about the direction of that conservation-and the Tired Law is a statement about reaching absolute Zero.The first law of thermodynamic is a statement of the principle of conservation of energy.It can also be considered as defining a property,the internal energy.The Second law of Thermodynamic states that in all energy exchanges,if no energy enters or leaves the system,the potential energy of the state will always be less than that of the initial states.This is also commonly referred to as entropy.举例说明热力学定律应用:a cup of hot coffee left on a table eventually cools,but a cup of cool coffee in the same room never gets hot by itself.The high-temperature energy of the coffee is degraded(transformed into a less useful form at a lower temperature)once it is transferred to the surrounding air.An ordinary house is,in some respects,an exhibition hall filled with womders of thermodynamics.Many ordinary household utensils and applicances are designed,in whole or in part,by using the principles of thermodynamics.Some examples include the electric or gas range,the heating and air-condition systems,the refrigerator,the humidifier,the pressure cooker,the water heater,the iron,and even the computer,and the TV.On a large scale,thermodynamics plays a major part in the design and analysis of automotive engines,rockets,jet engine,and conventional or nuclear power plans,solar collectors,and the design of vehicle form ordinary cars to airplanes.绝热系统:isolated systems:not exchangeing heat,matter or work with their environment.开口系统:exchanging energy(heat and work)and matter with their environment.闭口系统:exchangeing energy(heat and work)but not matter with their environment.孤立系统:rigid boundary :not allowing exchange of work.辐射换热:The mechanism in this case is electromagnetic radiation.We shall limit our discussion to electromagnetic radiation which is propagated as a result of a temperature difference;this is called thermal radiation.对流传热:when a fluid at rest or in motion is in contact with a surface at a temperature different from the plate ,energy flows in the direction of the lower temperature as required by the principle of thermodynamics.we say that heat is convected away ,and we call the process convection heat transfer.对流传热的方式:There are two convection modes :forced convection and natural convection.If a heated plate were exposed to ambient room air without an external source of motion ,a movement of the air would be experienced as a result of the density gradients near the plate.We call this natural ,or free ,convection as opposed to forced convection ,which is experienced in the case of the fan blowing air over a plate.传热学:Heat transfer is the science that seeks to predict the energy transfer that may take place between material bodies as a result of a temperature difference.传热学和热力学的区别:Thermodynamics teaches that this energy transfer is defined as heat.The science of heat transfer seeks not merely to explain how heat energy may be transferred ,but also to predict the rate at which the exchange will take place under certain specified conditions.The fact that a heat-transfer rate is the desired objective of an analysis points out the difference between heat transfer and thermodynamics.Thermodynamics deals with systems in equilibrium;it may be used to predict the amount of energy required to change a system from one equilibrium state to another;it may not be used to predict how fast a change will take place since the system is not in equilibrium during the process.Heat transfer supplements the first and second principles of thermodynamics by providing additional experimental rules which may be used to establish energy-transfer rates.As in the science of thermodynamics ,the experimental rules used as a basis of the subject of heat transfer are rather simple and easily expanded to encompass a variety of practical situations.影响辐射传热的因素:To take account of the “gray” nature of such surface we introduce another factor into
Equation ,called the emissive ε:which relates the radiation of the “gray”surface to that of an ideal black surface.We must take into account the fact that not all the radiation leaving one surface will reach the other surface since electromagnic radiation travels in straight lines and some will be lost to the surroundings.热能与动力工程thermal energy and power engineering 能量转化energy-transfer 比例常数proportionality constant 比例系数proportionality factor 活性中心active center 对流传热convection heat transfer 电磁辐射electromagnetic radiation 角系数view factor 准静态过程quasi-static process 准平衡quasi-equilibrium 静态平衡static equilibrium 强度参数intensive property 广延参数extensive property 燃烧机理combustion mechanism平均分子运动average molecular motion 热反应堆thermal reactor 热力学性质 thermodynamic property 摩尔热容molar heat capacity 动能kinetic energy 压缩因子compressibility factor 温度传感器temperature sensor 测量电路measurement circuit 电压输出voltage output 静电荷electrostatic charge 励磁电源excitation power 内能internal energy 能量原理energy principle 能量平衡energy balance 能量守恒conservation of energy 剪切应力shear force/stress 角速度angular velocity 速度梯度velocity gradient 温度梯度temperature gradient 一维one-dimensional 机械能mechanical energy 内能internal energy 动能kinetic energy 势能potential energy 凝固/硬化take a set 流体动力学fluid dynamic hydrodynamics 蒸汽发生系统steam generating system 辅助设备auxiliary equipment 空煤比the air-coal ratio 质量作用定律the law of mass action 阿伦尼乌斯定律arrhennius law 活化分子active molecule 活化分子碎片active molecule fragments 活化能activation energy
