摘
要:天然气加热炉是工业中重要的加热设备,固成本、技术等原因导致目前普遍存在加热方
式落后、效率低、浪费严重等问题,如何节能是一个垂待解决的问题。本文综述了目前加热炉在燃烧器、炉村材料、余热回收等方面采取的节能方法,炉内传热进行分析的基础,提出了一些小型加热炉的节能措施,对于加热炉的优化设计和应用推广有一定参考价值。
关键词:天然气加热炉节能

Abstract: As an indispensable heating equipment, gas-fired furnace is commonly faced up with low
eficiency and energy wastage due to cost limitation and technology issues. Energy conservation is a serious problem remaining to be solved. In this paper some technical measures to save energy was discussed, including burners, linings, waste heat recovery, etc. Based upon heat transfer analysis, energy conservation methods was put forward for small-size furnace. The conclusion was helpful for optimum design and utilization of natural gas in furnaces.
Keywords:natural gasindustrial fumaceenergy conservation
5.2结论
通过对城市燃气钢制管网防腐层检测方法的比较,认定目前比较实用的检测方法是人体电容法;将此技术应用于惠州城市燃气管网的外防腐层检测并结合开挖验证了此技术的科学性和实用性;通过此次检测和挖坑发现有以下问题存在:燃气管线与其他管线间距不合理、燃气管线敷设埋深不合理、管道阴极保护安装的牺性阳极不合理,部分管道欠阴极保护效果
等,并对于以上问题提出合理建议。万方数据
