Melting point 3410 ℃, boiling point 560 ℃, relative density of 1935, F the external electronic structure of 5d46s2, in the chemical reaction time is very easy to lose 1-6 electronic, but also can get 1-2 electronic, so oxidation number of 0,± 1,± 2, 3, 4 , 5 and 6, with 6 price of the most stable compounds, such as WO3 does not dissolve in water, the air will form in the tungsten trioxide thin protective layer of tungsten, tungsten with fluorine at room temperature, chemical combination, red hot when there is no moisture and Bromine iodide together, red hot when you can and water reaction WO3, at room temperature reaction of tungsten with aqua regia, but the hot concentrated hydrochloric acid and sulfuric acid can only be played with its weak response, but molten nitrate, nitrite, too Hydrogen peroxide, sulfur steam, steam and other phosphorus can play intense reaction, high temperature can not be carbon, boron and silicon reaction of binary compounds, widely used in industrial tungsten steel and tungsten carbide, pure tungsten filament is used to the system, and X-ray tube Tube heating components, semiconductor components can be prepared tungsten silicide, tungsten industrial production is white or black tungsten ore tungsten ore refining.

熔点3410℃，沸点560℃，相对密度1935，F外围电子结构为5d46s2，在化学反应时很容易丢掉1—6个电子，也能得到1—2个电子，所以氧化数为0、±1、±2、＋3、＋4、＋5和＋6，以＋6价化合物最稳定，如WO3不溶于水，空气中的钨会形成薄层三氧化钨保护层，钨能与氟在室温下化合，红热并无潮气时能与溴、碘化合，红热时还能和水反应生成WO3，室温下钨可与王水反应，但热的浓盐酸和硫酸只能与其起微弱反应，但对熔融的硝酸盐、亚硝酸盐、过氧化氢、硫蒸汽、磷蒸汽等能起激烈反应，高温下不能与碳、硼和硅反应生成二元化合物，工业上广泛使用钨钢和碳化钨，纯钨用来制灯丝、电子管和X射线管的发热元件，硅化钨可制半导体元件，钨工业生产是将白钨矿石或黑钨矿石精炼。

Contract:This article disausses the principal of main steam temperature control system according the problems in running,including the unreasonable main steam pressure set point volue,hot air injection flow is not acciurate,Charge of steam temperature has the big delay and the common PID can′t satisfy the regulate′s demandthen take the according measures,adopt smith predictor,change to ABB intelligent positioner,add the hot air injection antiblock device,test the main steam temperature automation and optimization the specificator.

中国国电集团公司菏泽发电厂热工，山东摘要：本文论述汽温控制系统组成原理，针对运行中发现的问题，包括一次风母管压力自动设定值设计不合理，导致主汽温度和再热汽温度变化幅度加大，底部注入风量和汽温参数测量不准确，汽温变化迟延大，常规PID满足不了调节要求，采取了相应措施，改用史密斯预测器，更换为ABB定位器，增加底部注入风量等测点防堵装置，并对主汽温自动进行试验和参数优化。

It is different with the manual exhaust Slurry pumps valve is not required to run the wind man, it must be installed on the location of gas pipeline set point, the so-called water gas gathering point is the top horizontal tube of the highest point, this horizontal pipe 3 ‰ gradient requirements, does not allow for local conditions such as depression and bending, when the air into the valve, the valve automatically opens, the air removed, the water level rose, it will automatically close the valve, hot water can not spill, from a virtually eliminating Manual exhaust is not timely, easy to form a "vapor lock" effect caused by hot water heating effects and huge loss of the state.

它与手动排气闸阀不同点是不需要人为跑风，它安装的位置一定要在管路集气点上，所谓集气点就是顶层供水横管的最高点处，对此横管有3‰倾斜度要求，不允许出现局部凹陷和弯曲等情况，当空气进入阀体后，阀门会自动开启，调节阀空气排除后水位上升，它会自动关阀，热水不能外溢，从根本上消除了手动排气不及时，易形成"气阻"影响供热效果和造成热水大量流失的弊端。
