A Study On High Temperature And High Pressure Pulverized Coal Fired Boiler Installation Engineering Technical Improvement And Cost Control

Boiler installation process is a continuation of the manufacturing process. The boiler products high temperature and high pressure steam, and it is suitable for all kinds of fuel, high thermal efficiency, heating surface complex. Modern power plant boiler is most large, complex, technology of complete sets of sex is strong, is a multidisciplinary and integrated many kinds of industrial products formed of the steam generator.This article main research on Jingbian Energy comprehensive utilization project thermal power station 4 units of 320 t/H high temperature and high pressure boiler construction site installation process and field construction cost control.The boiler models:X320/10.6-II1.This for π type of high temperature and high pressure natural circulation boiler steam drum pulverized coal furnace, single furnace, a tangential firing method, balanced ventilation, solid-state slag discharge, full suspension structure is used in heating furnace frame steel structure with double row of column, half open layout of coal-fired boiler.Due to high parameter, large capacity, power plant boiler huge volume, complex structures and systems and more for the suspension structure, large parts number, high technical requirements and complex, installation quality control links, compact installation period long, work quantity is big, and combination, installation in construction field, compared with bulk industrial boiler installation, the installation technology has its typical characteristics.Start the project of comprehensive utilization to jingbian-yanshuiguang pipeline energy chemical industry the entire unit internal heat power station 4 units of 320 t/H boiler installation of high temperature and high pressure, for example, boiler steel, boiler drum boiler, air preheater, burner, heating and other main components installation process are studied and summarized, and connecting with the actual production, the construction process of quality defects prevention and control measures are put forward, finally has obtained the good effect.
