We have to look at the concept of Shanxi fan air volume and pressure, the air volume actually refers to the speed of the fan-ventilated area and the plane of the plot. The ventilation area is subtracted from the value of the projected area of ??the outlet area of ??the tongue at the vortex obtained, the plane is the velocity of the air flow rate through time. When the plane speed is constant, the larger the ventilation area, that is, the larger the outer diameter of the impeller blades, the greater the amount of wind. The larger the amount of wind, the air, the greater heat absorption, thermal effect is more obvious fan. Fan is a prime mover of the mechanical energy is converted to transport gas to give mechanical blower gas energy supply, which is essential for thermal power plants in the supply of machinery and equipment boiler fans, mainly blower, induced draft fan, a fan, sealing fan and ranked powder machine, power consumption accounts for about 1.5% to 3.0% of the power plant generating capacity. In actual operation of thermal power plants, fans, especially due to the induced draft fan operating conditions than the poor supply proof axial fans, high failure rate, according to the statistics, the annual average of the induced draft fan failure is twice the average annual efficiency motor blower failure was 0.4 times, resulting in unplanned outages or load shedding operation. Therefore, the supply fan, quickly determine the cause of the failure to produce the fan is running, to take effective measures to solve is to protect the safe operation of power plants. Although the failure of many types of fans, the reason is very complex, but the actual operation of the plant according to the survey more fan failure are: bearing vibration, bearing temperature is high, the rotor blades jam protection device malfunction.
