Abstract
The design chooses the different pulverizing equipment and projects the different pattern pulverizing system according to the boiler’s capacity of Qinghe power plant extension project and the difference of the coal type. It also determines related equipments through the calculation on boiler burning, thermal calculation and aerodynamic calculation on the pulverizing system as well as calculation on shaping examination. The scope of pulverizing system including all equipment, components, piping and its components and instrumentation, regulation and control device which located in the original coal to the burner.This design besides basic equipment and components such as coal mill, coal feeder, separator, a fan or row machine, the original coal, coal gas and lock, the selection of design pieces separator, coal pulverizing pipeline, pipe and pipe etc of feeding pipeline design and reasonable decorate.Based on the system and equipment to make the parameter calculation, coal pulverizing system can adapt to the characteristics and has good performance and technical and economic indexes.
