At present, the effect of water-cooled with fans before the water can seal the final result is not easy to wear worn bearings leaking much time filling oil. Boiler Fan use higher temperatures, with tiny dust particles, low temperature, sulfur dioxide gas and water vapor will turn into sulfuric acid it will corrode the body, is still a large amount of carbon dioxide and other gases have some corrosion, so its easily broken. Boiler Fan the media, in addition to water vapor oxidation of fans, there are two things that damage Boiler Fan of the most important reasons: 1, dust on the fan casing, especially scouring effect on the impeller. 2, sulfur dioxide in the flue gas in contact with water generates sulfuric acid corrosion of the fan. Select fans need to be cautious to avoid accidents due to the current boiler centrifugal induced draft fan pressure is beyond the limits of the original fan pressure, the impeller design techniques used to strengthen the structure. After the intensity calculated according to the circumferential speed of the impeller, through the use of wheel cover imports stiffening ring, that is, first use of forged materials processing, and wheel covers juxtaposition. Meanwhile, the wheel cover export reinforcing ring and blade strengthen export structures, and computational requirements bend wheel, using roulette strengthened structure ensures that the centrifugal fan impeller welded construction for safe operation at high peripheral speed of Shanxi fan, in order to achieve meet the requirements of high pressure. Fan blade impeller blades linear logarithmic spiral. Exit angle is large, will help improve the function force the fan, fan blades and improve wear resistance. Leaf blade with a relatively narrow width, which will help improve the efficiency of the fan running in traffic on a smaller area, expand the operating range of the fan, improve the reliability of the fan. Consideration for high line speeds, fan blades can be curved design of two, in order to increase the force area, thereby increasing resilience flow problems caused by stress increases. Of course, making the induced draft fan, Shanxi, in the choice of product, first look at its parameters. In the choice of variable pitch axial fan parameters, in addition to the provisions given in accordance with the relevant regulations cited fan Shanxi margin givers offer, but also according to the actual situation of the power plant in Shanxi drawing fan pictures, not only considering the maximum guaranteed operating point, but also consider Ignition safety and working conditions as well as the fan case turner. After two conditions often overlooked and difficult to debug and run the fan, so in actual operation must be very careful to avoid accidents.
