Supervision And Practice Of Boiler Installation Equipment Supervision For Large Thermal Power Units

Supervision is an important link to safeguard the quality of equipm ent.To better implement the equipment installation phase of the supervision of the power transmission and transformation project and combine with 1000 MW boiler installation engineering supervision practice,this paper puts forward the chemical cleaning,the wash pipe unit reference endoscopy and other advanced inspection means based on the structure of 1000 MW,and the key points of quality control,installation process and the basic scheme of large thermal power unit,the scene of the heating surface of boiler installation clean construction control.Through the equipment storage,composition,installation,hidden check to the branch of unit commissioning of process planning and control,the establishment of boiler installation clean construction control scheme,we have effectively guaranteed thr protection of unit start-up and commercial operation of a complete set of reliable safeguard.According to characteristics of boiler installation,we have made a risk assessment and safety supervision to ensure the quality of engineering construction,which has important guiding significance and economic benefits,thus can fundamentally guarantee the supervision effect.The main work and achievements are as follows:1.Combining with the PI of 1000 MW boiler equipment installation requirements,this paper introduces the important composition of the unit,optimizes the installation process and summarizes the key link of 1000 MW boiler installation supervision control measures.By installing supervision practice and b eing familiar with the structure,we set up quality inspection partition table,serving as a guide for boiler installation quality control standards.2.Ensure the stable boiler operation when doing the cleanness work and prvent the occurrence of pipe explosion.Through controlling the boiler overall clean construction measures,from equipment check to install process control,and to the chemical cleaning and the check of the wash pipe,this article has carried out various controls and obtained good control experience and control effect.3.Through controlling the key construction of major measures and the LECD analysis construction work on major construction,we must identify and prevent hazards in order to achieve a safe production environment.
