| Abstract: | Adopts the frequency conversion regulating velocity technology for boiler fans, may change the rotate speed of the fans, thereby change the feed wind capacity, the technology has hereinafter excellence: high precision of regulating velocity, small startup current, reducing the vibration and friction of mechanisms, operation briefness. Domestic power plants make widely use of the high-high and multiple electric balance mode of high voltage frequency conversion regulating velocity now. The application result of 100MW, 200MW and 300MW units s fans indicate: the frequency conversion regulating velocity technology may obtain high economic benefit in power plant. |
