课程名称：工业锅炉与除氧器 概述：本课程旨在详细讲解工业锅炉和除氧器及其相关设备。课程内容涵盖以下主题：锅炉的功能、工作原理，蒸汽鼓、沉淀鼓、上升管和水管的布局与功能，安全排放阀、视液位计、连续与间歇排污。锅炉设计中各相关设备的安装位置。对于锅炉中的过热器、过热蒸汽与饱和蒸汽的优缺点进行分析，并学习如何视觉识别这两种系统。经济器及其与过热器的区别，蒸汽鼓内部结构及不同类型的过滤系统（如挡板、旋风分离器、初级和次级分离器）的功能与优点。课程还讲解了除氧器的工作原理（包括加压和真空型），基于亨利定律，以简单易懂的方式说明功能。课程内容包括向除氧器腔内引入蒸汽的原因，加压和真空除氧器内设备（如喷嘴、托盘、真空引射器）及其如何在容器内创造真空的原理，包括抽吸、排放和动力蒸汽的功能。同时，课程提供了真实的压力和溶解气体的例子，分析不同类型的除氧器及其效率，以及除氧后氧气的数量。介绍了用于从除氧器中去除氧气的机械和化学机制。最后，还会讲解锅炉炉膛与燃烧系统，强制、引导与自然通风的原理，以及完全与不完全燃烧，不同类型的燃烧器及其功能。 该课程无大纲，适合希望深入了解工业锅炉与除氧器操作及设计的学员。
This course is created to explain Industrial Boilers and deaerators and their associated equipment. Topics like Boiler function, working principle, Layout and the function of steam drum, mud drum, riser and water tubes, safety relief valves, sigh gauge glass, continuous and intermittent blowdown. Location of all the associated equipment of the boiler according to boiler design. Superheaters need in boilers. Superheated steam and saturated steam and their advantages and disadvantages. Visual identification of saturated and superheated system. Economizer and its differences with superheater.Steam Drum internals and the function and benefits of using different types of filtration system in the steam drum as Baffles, cyclone separators, primary and secondary separators. Deaerators (pressurized and vacuum type) working principle based on henrys laws are explained in a very easy and understandable way. The reason of introducing steam into deaerator chamber. Pressurized and vacuum deaerators inside equipment's such as spray nozzles, Trays Vacuum ejector and how it creates Vacuum in a vessel with its suction, discharge and motive steam. Real Life practical example of Pressure and solubility of dissolved gasesTypes of Deaerators.Efficiency of Deaerator and oxygen quantity after Deaeration. The mechanical and chemical mechanisms used to remove oxygen from Deaerator. Boiler Furnace and combustion system. Forced, Induced and natural draft. Complete and incomplete combustion. Different types of burners and their function. are explained.
