蒸汽锅炉

You must prevent circumfluenting to the boiler if the boiler closes chake valve. Rail pressure valve and buffer pistons in the act of gravity can realize the pressurize immediately to make the steam and condensate water not to circumfluent to the boiler in low pressure.

如果锅炉没有关闭截止止回阀，则必须防止回流到锅炉上，阀瓣压铁和缓冲活塞，在重力的作用下，能够迅速实现密封，使得蒸汽和冷凝水即使在低压下也不会回流到锅炉里。

boiler is a important power equipment,the require is to provide qualified vapour,let the amount of vapour maked by boiler suit for the load.because of this,every main parameter in the process of the product should be strict controlled.this paper is introduced same main control system in the process of boiler control、concentrate and disperse control system 、the characteristic and the develop of the MCGS compose status software.integrate with the technique of the boiler, discuss the single momentum, double momentum, three momentum boiler control system distinguishly.we think in the process of micro boiler control, three momentum control is the best choice,and has been well implemented in the water level mediation.further more,use the concentrate and disperse control and MCGS compose statue sofeware can achieve the control of the boiler,and can reach a fine effect..

锅炉是一个重要的动力设备，其要求是供给合格的蒸汽，使锅炉发气量适合负荷的需要。为此，生产过程的各个主要参数必须严格控制。本设计了研究锅炉控制过程的几个主要控制系统，以及集散控制系统和MCGS组态软件的特点和发展状况。结合锅炉的工艺情况，针对单冲量、双冲量、三冲量锅炉控制系统，对它们存在的利弊做出了比较和分析。结合生产实践，对三冲量的算法进行比较，认为在小型锅炉控制过程中，三冲量控制是最好的选择，并在水位调节中得到很好的应用。

On account of the fact that the signal of total boiler radiant energy fully embodies the changes of combustion conditions in a boiler and can foreshow the variation trend of inlet flue gas temperature , the signal of total boiler radiant energy is introduced in the control system for superheated steam temperature .

鉴于锅炉总辐射能信号充分体现了锅炉内燃烧工况的变化，能提前反映烟道进口烟温变化趋势，为此，在过热蒸汽温度控制系统中引入了锅炉总辐射能信号，通过检测烟气温度及其变化趋势来提前调节减温水量，从而改善主蒸汽温度调节的品质。

According to the running state of the Boiler in Datang Huxian County Second Power Plant, the steam atomizing oil gun was reconstructed to the air atomizing oil gun. The compressed air was used to the atomizing medium of the oil gun that a great quantity of the steam was reduced when the boiler had been no running and steady boiling. Definitely the steam may be supplied by the steam turbine the fourth pulling out section,oil gun's use was not limited by the pressure of the atomizing steam at lower load. It has been realized the energy conservation efficiency function.

大唐户县第二发电厂根据锅炉运行的实际情况，通过将蒸汽雾化大油枪改造为空气雾化油枪，采用压缩空气作为油枪雾化的介质，大大降低燃煤锅炉起停及稳燃时蒸汽耗量，辅汽联箱不需要冷段再热部分供汽，完全可以由汽轮机四段抽汽供汽，油枪的使用不受低负荷时雾化汽源压力低的限制，达到了节能增效的作用。

For the proposed project the waste gas emission locations include: preheating furnace of hard alloy parts line (when natural gas is used for heating while excess heat heating system goes wrong), melting furnace, refining furnace, heat treatment furnace for machining unit and steam boiler. The pollutants are SO2, NOx and smoke dust contained in the smoke generated from the above locations. All the above pollution generating facilities use the most clean energy, natural gas, for burning. Meanwhile, on melting furnace and refining furnace low nitrogen combustion technology such as low NOx burner is applied, and the generated smoke is discharged via chimney.

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.
