Control of High-Temperature Furnace Field Heat Loss and Energy Efficiency Optimization Under Multiple Operating Conditions

摘要

高温热炉场是冶金、化工、建材等工业核心热能装备，能效直接关联企业生产成本、产品质量与环保水平。多工况切换为其典型特征，过程中炉内温度、压力等参数剧烈波动，致热损失路径复杂、损耗量波动大，严重制约能效提升。本文基于传热学，分析热损失类型及机理，探究工况切换影响规律，从五维度提优化方案，结合实例验证可行性，为该类装备节能降耗提供理论支撑与工程参考。

Abstract

High temperature furnaces are core thermal equipment in industries such as metallurgy, chemical engineering, and building materials. Energy efficiency is directly related to production costs, product quality, and environmental protection levels of enterprises. Multi condition switching is its typical feature, during which parameters such as temperature and pressure inside the furnace fluctuate violently, resulting in complex heat loss paths and large fluctuations in loss amounts, seriously restricting energy efficiency improvement. This article is based on heat transfer, analyzing the types and mechanisms of heat loss, exploring the impact of working condition switching, proposing optimization solutions from five dimensions, and verifying feasibility with examples, providing theoretical support and engineering reference for energy conservation and consumption reduction of such equipment.
