火电厂300MW机组热力部分和制粉燃烧系统设计(抚顺烟煤)摘要

1、火电厂300MW机组热力部分和制粉燃烧系统设计（抚顺烟煤）摘 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

2、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，烟风管道的计算及选取。 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 milling (Fushun coal)Abstract I ma

3、de this preliminary design，which is Combustion systems for thermal power plant 300MW unit of the milling and thermal part of the eight heating system, . As technology advances, the capacity of the units of thermal power plants is increasing, and relatively lower investment per kilowatt of installed

4、capacity building. Although the power plant capacity of the units is growing, but needed less and less staff, which fully reflects the high-tech in its workers wages are relatively reducing personal income increasing, the efficiency is improved . Joint project on the basis of the full absorption of

5、the former experience, the actual situation, already more mature thermal system has been further optimized to make it more realistic, but also to make the investment can be reduced. This design was completed for the calculation of combustion systems, milling system calculation, the calculation of sm
