Quality Control Of Coal Mill In Million Kilowatt Class Thermal Power Plant

Coal mill, an important auxiliary equipment of thermal power station, plays an essential role to ensure the safe and stable operation of thermal power station. The paper studies the quality control of the coal mill in processing details in million kilowatt unit in our country, including design, procurement, manufacture, installation, commissioning and maintenance process. Based on the obersavation and control of the coal mill in Wanzhou port electric company, the study analyzes the problems of the coal mill and the quality control of coal mill in each step is realized.The paper describes the problems and solutions in the installation and commissioning of the coal mill in Chaozhou Guangdong power plant, Huaneng Yuhuan power plant, Ninghai power plant and Wanzhou port electric company. In order to control the quality of the coal mill. The construction period of the coal mill in Chaozhou Guangdong power plant is estimated. Timely adjustment to ensure that the installation period of the coal grinding machine is reasonable. Analysis of installation quality in the process of the construction of the coal mill power plant of Huaneng Yuhuan power plant. In the next step, the emphasis of the construction quality is put forward. The construction organization of the coal mill in Ninghai power plant is introduced. To ensure the quality control in the construction process of the coal mill.The whole construction process of Wanzhou port electric company, Witness from the manufacturing process, Setup step decomposition control, Construction technical specification writing execution, Site important node acceptance, Not to comply with the notice, The quality control of the grinding coal machine is revealed by the multi angle of the implementation of the tracking file. Ensure the quality of the grinding machine in the installation phase, The importance of equipment supervision is demonstrated. It provides a valuable reference for quality control of boiler and steam turbine equipments for million kilowatt thermal power by analyzing coal mill in million kilowatt plant in the method of overall. quality-management.
