350MW supercritical boiler burner nozzle tube screen device and method. At present, domestic 300MW lignite boilers are all subcritical, and the steam parameters are low, which leads to low operating efficiency of power plants; according to the national "Eleventh Five-Year Plan" energy planning and the requirements of industrial structure adjustment and energy saving and consumption reduction, develop high-parameter, high-efficiency supercritical A boiler is imperative. A 350MW supercritical boiler burner nozzle tube panel device, which consists of a tube panel (1) connected to the pipes. The tubes and the load protruding part of the tube panel are connected to the burner and the water wall of the boiler by connecting pieces, and the burner and the water wall are connected to the frame beam through the tension plate. The invention is used for the nozzle tube screen of the 350MW supercritical boiler burner.
