The purpose of the rectifier grid: In recent years, with the continuous development and progress of technology, the domestic boiler manufacturing industry has also made rapid development. Small-capacity boilers have gradually been eliminated, and large-capacity, high-parameter boilers have become the mainstream of the current power industry. On the boilers used nowadays, denitrification requires the use of large-area rectifier grids. Specification and size of the rectifier grid: The commonly used steel grating plates generally have a height of less than 60mm. The rectifier grids used in China generally have a height of more than 300mm and a thickness of more than 3mm. The mesh size is between 100mm/321mm, and the plates are produced by opening and inserting full welding, which has strict requirements in welding requirements and other aspects. The size varies, generally with a long length of about 10 meters and a width of about 3 meters. As the length is long, the processing and production cycle is relatively long. It is recommended that customers pre-order in advance, and the size is generally customized according to the drawing. Material of the rectifier grid: The rectifier grid for boilers must be made of Q345材质 flat steel, and cannot use Q235 material. Surface treatment: As the rectifier grid is relatively heavy in weight, the surface treatment methods are relatively simple, generally surface anti-rust paint treatment, and then one surface paint is applied.
