When the coal pulverizing system, first of all according to the boilers given parameters and characteristic of coal kind were auxiliary boiler calculation; then based on coal characteristics determine the pulverizing system and the type of coal mill; and the pulverizing system of thermal calculation, pulverizing system of aerodynamic calculation, pulverizing system, pipeline design and calculation, selection of auxiliary equipment for pulverizing system, and ultimately determine the suitable for Huainan bituminous coal pulverizing system and the coal machine type grinding. Calculation of the burner design, you first need to the burner combustion mode was determined, and then calculating the primary air and secondary air outlet layers, at the end of the primary and secondary air ratio and selecting etc. some design calculations that burner arrangement, output and size.
