W5-48 high temperature fan performance fan performance and selection generally refers to gas transport performance in specified state. Specifies the state of the fans is: Pa = 101325Pa kiln atmospheric conditions of high temperature fans, media w472-temperature flue gas fan, the gas temperature t = 400 ℃, gas density ρ = 0.522kg / m3. Performance Table with damper fans refer to the parameter when the damper blade is fully open (0 °) when. Many often occurs excess or shortage flow in use, the reasons for this phenomenon. As large a small event in the course of the phenomenon, mainly due to the resistance of the pipe network in big, sometimes small. As in the course, over a longer time decreases, or a sudden decrease in a short time, mainly due to the fan flow channel or pipe blockage. After installation, the excessive or insufficient flow behavior can occur when a formal operation, the main reasons are the following: the pipe network resistance difference between the actual value and the calculated value is too large by the general pipe network characteristic equation: P = KQ2, where K - the actual value of the drag coefficient as the flow rate increases less than the calculated temperature fan when K K, otherwise the flow rate decreases. 2. Select the fan itself is not considered when the full impact of the deviation △ P pressure value, the actual value is positive when the fan is poor, the flow rate increases, the difference is negative, then the flow rate decreases. 3, the fan occur in the course of heavy traffic or too small can be used to regulate the flow damper. When adjusting the doors open, the flow rate is still too small, the elimination of one of the following methods may be used: ① change the pipe network, reducing the drag coefficient of the tube network. ② increase the fan speed high temperature turbine prices, but not greater than the maximum speed of the aircraft performance table number. ③ Select the new high pressure turbine. W5-47 boiler centrifugal induced draft fan with low noise, simple structure, flexible regulation of the air volume, wind direction, and is applicable to various coal-fired industrial boilers are equipped with smoke and dust removal device. Delivery gas temperature ≤900 ℃. The fan drive way there are two kinds of C-type and D, with water-cooled bearing overall air volume damper. Such as the choice of shock absorbers, the user can directly place the fan on a concrete plane, without bolt, easy installation.
