1、火电厂火电厂 300MW 机组热力部分和制粉燃烧系统设计（抚顺烟煤）机组热力部分和制粉燃烧系统设计（抚顺烟煤）摘摘 要要针对火力发电厂 300MW 机组的制粉燃烧系统及热力部分的八级加热系统，本人做出初步设计。随着技术的发展，火电厂机组容量不断增大，每千瓦装机容量的建设的投资相对降低。虽然电厂机组容量越来越大，但是所需要的工作人员越来越少，这也充分体现高科技在其上的，工人总的工资相对减少，而个人收入不断增加，效率也就提高了。在充分吸收前任经验的基础上，接合工程实际情况，对原已较成熟的热力系统作了进一步优化，使其更符合实际情况，同时还使投资得以降低。本次设计首先完列出了该设计总的概况，然后依次为
2、燃烧系统计算，制粉系统计算，烟风管道的计算及选取，原则性热力计算，以及全面性热力系统的拟定及其辅助设备的选择，其中主要是对全厂性热力系统的拟定。在热力系统的计算设计中，对各个局部热力系统及其辅助设备的选择，对原则性热力系统的计算和热力系统的拟定，对原则性热力系统的计算时采用按定汽轮机进气量的计算方法。在燃烧、制粉系统计算设计中，燃烧及制粉系统设备选择，0D烟风管道的计算及选取。关键词：关键词：燃烧系统；原则性热力系统；制粉系统；全面性热力系统300MW units in thermal power plant thermal combustion system design and flour
