A year ago, wrangling over the price of gas sold by Russia to Ukraine briefly diminished the flow of gas through Ukraine to Europe. At the end of 2006, Belarusian resistance to Russia's demand that it too pay more for gas threatened to unleash another so-called "gas war".

一年前，围绕俄罗斯销往乌克兰的天然气价格之争使得途经乌克兰输送至欧洲的天然气量锐减。2006年底，俄罗斯提出要对销往白俄罗斯的天然气进行涨价，白俄罗斯人对此进行了抵制，新一轮所谓的&天然气之战&一触即发。

Russia and Ukraine have been disputing more intensify in gas prices and gas transit issues for many years. The natural gas dispute between the two countries has become regular program after the"Orange Revolution". At the beginning of this New Year, a"gas war"once again cast a shadow on relations between Russia and Ukraine. But an agreement ultimately has been reached between the two countries through many times coordination by the European Union, that means the end of the struggle.

多年来，俄罗斯和乌克兰两国在天然气价格和天然气过境问题上的争执愈演愈烈，两国之间的天然气纠纷几乎成了&橙色革命&之后的定时节目。2009年初的一场&天然气大战&再次给俄乌关系蒙上阴影，但在欧盟多次协调下两国最终以达成协议方式而结束了争斗。

The temperature of flue gas out of air preheater in boiler is normally about 120～180℃, the flue gas enter the absorb tower from the bottom via pre-deduster and is accelerated by venturi tube at the bottom of absorb tower, then is taken to circulating fluid bed. The materials are in the circulating fluid bed, due to the effect of flow, the gas-phase and solid-phase generate fierce turbulence and combination and are fully contacted, then form polymers constantly during the ascending and return downward, while the polymers are constantly disassembled during fierce turbulence and elevated by airflow, which makes the slip velocity between gas and solid reach the tenfold times of single slip velocity.

首先从锅炉的空气预热器出来的烟气温度一般为120～180℃左右，通过预除尘器后从底部进入吸收塔，然后烟气通过吸收塔底部的文丘里管的加速，进入循环流化床，物料在循环流化床里，气固两相由于气流的作用，产生激烈的湍动与混合，充分接触，在上升的过程中，不断形成聚团物向下返回，而聚团物在激烈湍动中又不断解体重新被气流提升，使得气固间的滑移速度高达单颗粒滑移速度的数十倍。

The content of this design is examining and controlling the virulent gas. The system examines virulent gas with gas senor and reduces the density of virulent gas by ventilating fan and controls it in safe scope.

摘 要：本次设计内容是有毒气体的检测与控制，通过气敏传感器对有毒气体进行检测，并通过换气扇降低有毒气体浓度，将其控制在安全的范围内。

In the present work, based on the mechanism of low - temperature corrosion, an opinion was presented by theoretical analysis and computation, that is the vacuum boiler can not avoid being corroded completely under low temperature, but the corrosion is very weak no matter if the exhaust gas temperature is higher than the flue gas dew point; it was obtained the relationship between the corrosion velocity of metal wall and wall temperature along gas pass of vacuum boiler, and the one between the corrosion velocity of metal wall and wall temperature under the condition that the flue gas temperature is lower than the acid dew point.

文章从锅炉发生低温腐蚀的机理人手，通过理论分析计算并通过实践检验，提出了真空相变锅炉虽然不能完全避免低温腐蚀问题，但不论排烟温度是否高于烟气露点，低温腐蚀的程度都很弱的观点；给出了真空相变锅炉沿烟气流程金属壁面的腐蚀速度与壁面温度的关系曲线，和烟气温度低于酸露点时金属壁面的腐蚀速度与壁面温度的关系曲线；同时，文章推荐真空相变锅炉的设计排烟温度取130℃左右的低排烟温度。
