Since early 2000, Mr. Jörgen Linnér has been instrumental in developing the fourth generation of the switched integrated rectifier (SIR), ANDRITZ´s latest version of its advanced ESP energizer. It combines modern solid-state power electronics with switching technology and uses advanced energy management software to optimize the power consumption while ensuring compliance with emission limits.
In recent years, Jörgen has further increased the electrical efficiency of the SIR unit by successfully introducing silicon carbide (SiC) components in its design. With SiC-based power modules, ANDRITZ can now offer its customers a product with an electrical efficiency of over 97%, the benchmark in this industry.
In addition, Jörgen and the R&D team have enhanced the operating capabilities of the SIR so that it can be used in applications with high resistivity fly ashes.
Mr. Ronnie Uhr, Head of ANDRITZ Air Pollution Control PMCS, said: “We are extremely pleased that one of our engineers receives this award. The SIR drastically reduces particulate emissions and improves the overall electrostatic precipitators (ESP) performance to meet the demands of plant operators in reducing dust emissions from various combustion and industrial processes. It is a clear sign that with its SIR product, ANDRITZ is at the forefront of the ESP technology development”.
