1.Overview

In the boiler system, the operation efficiency of the fan directly affects the energy consumption and production cost, so the use of efficient and stable control technology is extremely important. The FGI FD5000 series high voltage frequency inverter is a solution designed for such needs, and its successful cases in boiler fan applications fully demonstrate its remarkable results in energy efficiency and system stability.

Fans play a vital role in modern industrial production and daily life, and are widely used in various scenarios to ensure the smooth progress of key processes such as air flow, heat exchange, environmental control and material transportation. Specifically, the applications of fans in different fields include: boiler systems, central air conditioning systems, cooling towers, production site exhaust systems, dryer production lines, etc. 

In view of the wide application of fans in various industrial and mining enterprises, they have become one of the main power equipment. According to statistics from relevant departments, the installed motor capacity of fans and pumps in China is as high as 35,000 megawatts, accounting for about 40% of the country's total power consumption. This means that the energy efficiency improvement of fans is of great significance for energy conservation and emission reduction, reducing enterprise operating costs and even promoting the optimization of the national energy structure. Therefore, the adoption of energy-efficient fan technologies and control systems, such as high-voltage frequency inverters, is essential to improve energy efficiency and promote sustainable development across the industry.

As the basic equipment in many industrial production, the operation efficiency and stability of industrial boiler system directly affect the energy consumption, production cost and environmental impact of enterprises. In the face of low operating efficiency, poor system stability, energy waste and other pain points, the introduction of the FGI FD5000 series high voltage frequency inverter has become an effective solution to optimize the performance of the boiler system and improve energy efficiency.

2. Implementation plans

In this boiler, there are four motors using FD5000 high voltage frequency inverter, respectively to control steam, hot oil, hot flue gas. The hot flue gas is controlled by two 315KW motors and sent to the main fan through the pipeline for drying the wood pulp. Two 315KW FD5000 high voltage frequency inverters respectively control the two fans.By using the FGI FD5000 series high voltage frequency inverter to adjust the output power of the fan, the precise control of the hot flue gas flow is achieved, which is compared with the traditional baffle or damper adjustment method,and is more energy saving than the hot smoke flow adjustment with the windshield.In this industrial process, the other two 132KW motors use advanced control technology, such as the FGI FD5000 series high voltage frequency inverter, to precisely adjust the output of the steam generator and the hot oil generator, its important role is reflected in the following aspects: Precise control of output, pressure and temperature management, energy efficiency, maintenance of equipment health, environmental and economic benefits.The FD5000 series high voltage frequency inverter also regulates the output of steam and the output of hot oil by controlling the output power of the motor, controlling the pressure and temperature of the steam generator and the temperature of the hot oil generator.
