Most high-temperature induced draft fans have the phenomenon of pulling a cart from a horse during use. In addition, due to changes in production and process, it is necessary to constantly adjust the gas flow, pressure, temperature, etc; At present, many units still adopt the backward way of adjusting the opening of the air baffle or valve to adjust the gas flow, pressure, temperature, etc. This is actually to meet the requirements of process and working conditions for gas flow regulation by artificially increasing resistance and at the cost of wasting electric energy and money. This backward regulation mode not only wastes valuable energy, but also has poor regulation accuracy, which is difficult to meet the requirements of modern industrial production and services, and has serious negative effects. The appearance of frequency converter has brought a revolution to AC speed regulation mode. With the continuous improvement and development of frequency conversion technology in recent ten years. The energy-saving and speed regulating performance of high-temperature induced draft fan is becoming increasingly perfect, which has been widely used in AC speed regulation in different fields. It has brought considerable economic benefits to enterprises and promoted the automation process of industrial production.
Operation curve of high-temperature induced draft fan
Dongguan Chengyi Energy Saving and Environmental Protection Equipment Co., Ltd. uses frequency converter to control the fan, which is an electricity saving method to reduce aerodynamic force. Compared with the commonly used method of regulating the air volume by regulating the air door, it has obvious energy saving effect.
