World's first pulverized coal burner with variable flame vector tested

A Russian thermal engineering institute, JSC VTI, has successfully tested the world’s first pulverized coal burner with a variable flame vector, marking a significant innovation in the global energy sector. This new vortex burner design enables vertical and horizontal adjustment of the flame direction within the combustion chamber, allowing adaptation to different fuel types and boiler operating conditions. The technology aims to reduce atmospheric pollution, particularly nitrogen oxide emissions, by optimizing the distribution of fuel and oxidizer along the flame. It also enhances economic efficiency and supports the technological independence of Russia’s domestic energy industry. The burner was pilot-tested at Tomsk State District Power Plant-2 under various loads, demonstrating stable operation of its mechanical components and effective control systems over a year-long trial. The variable flame vector helps stabilize superheated steam temperature, regulate heat absorption, and maintain uniform temperature distribution, thereby improving boiler reliability and efficiency. This flexibility is particularly valuable for switching between coal grades with differing ash content and calorific values, reducing slagging risks and maintaining optimal
