本课程旨在教授学员如何进行锅炉/蒸汽发生器的能源审计。 **课程概述：** 能源审计是一种测量能源流的方法。锅炉审计是监测蒸汽发生器性能的广泛采用的技术。蒸汽发生器在工业中广泛应用，特别是在流程工业中，对能源账单和碳足迹都有显著影响。在许多国家，能源审计是一项专业工作，由顾问为企业提供服务，帮助他们节省能源和资金。因此，掌握审计高能耗系统（如锅炉）的技能可以提高就业能力。 本课程首先介绍蒸汽的性质以及蒸汽表的用法。熟悉蒸汽性质的学员可以跳过这些入门视频讲座。 随后，课程将介绍能源审计师所采用的两种方法： 1. **直接法（输入-输出法）：** 这种方法通过较少的读数和简化的计算，帮助学生轻松了解锅炉的性能。然而，此方法准确性稍低，且难以深入分析降低蒸汽发生器损耗的方法。 2. **热损失法（间接法）：** 这是一种更全面的评估锅炉性能的工具。通过一系列视频讲座，课程将详细解释间接法。学生将学习如何测量和计算锅炉的各种损失，从而间接得出锅炉效率。课程还将重点讨论烟气显热损失对锅炉性能的关键影响以及如何减少这些损失，并对其他损失进行探讨。每项损失的计算都需要相应的测量，课程将讨论这些测量方法以及用于蒸汽发生器审计的仪表。
Energy Audit is a method to measure energy flows.Boiler audit is a technique widely adopted to monitor the performance of steam generators.Steam generators are widely used in industries and would contribute to both the energy bill as well as carbon footprint in a big way especially if it is a process industry.In many countries energy auditing is a specialized job which consultants do for industries and help those save energy and money.Thus acquiring skills on how to audit energy guzzling systems like boilers makes a person employable.In this course students are first introduced to the properties of steam and then introduced to the use of steam tables. Those conversant with steam properties can skip these introductory video lectures.Students are then introduced to the two methods employed by energy auditors.Direct method or input -output method helps students gain insights into the performance of boiler easily and through less number of readings and back to envelope calculations.However this method is a bit inaccurate and fails to give insights on the ways to reduce losses from steam generators.Heat loss method or indirect method is elaborate tool to assess the performance of boilers. Through series of video lectures ,indirect method is explained.Students would learn to measure and calculate the losses from boilers and arrive at boiler efficiency indirectly. Heat losses from dry flue gases are critical and how they affect boiler performance and how to reduce those losses are discussed from conceptual perspective. Other losses are also discussed.Every loss to be computed would require appropriate measurements and those are discussed.The instruments used to audit the steam generators are introduced to the student.
