提高Ф50 m環(huán)形加熱爐熱效率的措施

Measures to Increase Heat Efficency of Φ50 m Rotary Heating Furnace

摘要: 分析某公司Ф50 m環(huán)形加熱爐投產(chǎn)初期的情況；針對投產(chǎn)初期存在問題進(jìn)行改進(jìn)：建立合理的環(huán)形爐運(yùn)行與維護(hù)方案，管理燃燒系統(tǒng)，增大有效換熱面積，以及優(yōu)化待軋降溫制度，建立待軋降溫預(yù)警機(jī)制和燃?xì)鈱崟r查詢錄入系統(tǒng)與績效考核制度等。通過改造，逐步降低了Ф50 m環(huán)形加熱爐的天然氣消耗，提高其熱效率至60%以上。

Abstract: The condition of the Φ50 m RHF of a certain company in its early start-up stage is analyzed and corresponding improvements are put forward, including establishing a reasonable operation and maintenance plan for RHF, managing the combustion system, increasing effective heat exchange area, optimizing the temperature decreasing mechanism at interruptions, creating a warning system for temperature decreasing at interruptions, a real-time gas inquiring and entering system and a performance assessment system etc.Through these revamping measures, the gas consumption of the Φ50 m RHF is gradually decreased, and the heat efficiency is increased to more than 60%.
