Abstract

The necessity to change systems generating electrical energy is evident. The best solution would be to use installations utilizing renewable energy sources, complemented by efficient electric energy storage. This process requires time and further development, as well as new achievements in this area. Improving the situation can also result from enhancing the efficiency of devices already in operation. For a coal-fired power block, an important aspect is the variability of loads and ensuring the highest efficiency of all devices that make up the technological chain of such a unit, especially in variable working conditions. The article presents a new solution for regulating the working parameters of a radial fan for use in power engineering, which has high efficiency over a wide range of loads. The proposed six-blade solution allows one to obtain 115 Pa higher total pressure compared to four-blade systems, and efficiencies higher by 4.6 percentage points. The process of selecting elements and design parameters of the fan and its control system is discussed. The performance characteristics of the device with the new control system are presented.
