【摘要】：锅炉安装过程是制造过程的继续。锅炉生产高温高压蒸汽,适用各种燃料,热效率高、受热面复杂。现代电站锅炉庞大、复杂,技术成套性强,是多学科、多门类工业产品综合而成的蒸汽发生装置。本文主要研究靖边能源化工综合利用启动项目装置内热电联产热动力站4台320T/H高温高压锅炉现场施工安装工艺和现场施工成本控制。锅炉型号:HX320/10.6-II1。本锅炉为高温高压π型自然循环汽包煤粉炉,单炉膛、四角切圆燃烧方式、平衡通风、固态排渣、受热面采用全悬吊结构,炉架钢结构采用双排柱,半露天布置的燃煤锅炉。由于高参数、大容量,电站锅炉体积庞大、结构和系统复杂且多为悬吊式结构、部件数量大、安装工艺要求高而复杂、安装质量控制环节多,安装工期长而紧凑,安装工程量大,且均在施工现场进行组合、安装,与散装工业锅炉安装相比,有其典型的安装工艺特点。本文以靖边能源化工综合利用启动项目整个装置内热动力站4台320T/H高温高压锅炉安装为例,就锅炉锅炉钢架、锅炉汽包、空气预热器、燃烧器、受热面等主要部件的安装工艺进行了研究和总结,并结合生产实际,对施工过程中出现的质量缺陷提出了防治措施,最终取得了良好的效果。
[Abstract]:The boiler installation process is the continuation of the manufacturing process. The boiler produces high-temperature and high-pressure steam, which is suitable for all kinds of fuels. The thermal efficiency is high, the heating surface is complex. This paper mainly studies the installation technology and site of 4 320 T / H high temperature and high pressure boilers in the project of comprehensive utilization and start-up of Jingbian energy and chemical industry. Construction cost control. Boiler type 1: HX320 / 10.6-II1.The boiler is a high temperature and high pressure 蟺 type natural circulation drum pulverized coal furnace. Single furnace, tangential combustion in four corners, balanced ventilation, solid slag discharge, full suspension structure for heating surface, double row column for furnace frame steel structure, semi-open layout for coal-fired boiler. Because of high parameters and large capacity, the volume of power station boiler is huge. The structure and system are complex and most of them are suspended structures, with large number of components, high and complex installation process requirements, many installation quality control links, long and compact installation period, large amount of installation works, and combination and installation at the construction site. Compared with the installation of bulk industrial boilers, this paper takes the installation of 4 320 T / H high temperature and high pressure boilers in the whole unit of Jingbian Energy and Chemical Industry Comprehensive Utilization Start-up Project as an example. The boiler steel frame and boiler drum are used as examples. The installation technology of air preheater, burner, heating surface and other main parts are studied and summarized. Combined with the production practice, preventive measures are put forward to prevent and cure the quality defects in the construction process, and good results are finally achieved.
