英文
furnace heater-
Abstract : the causes for low efficiency of the heater in no. 2 crude unit of jpc refinery are described and analyzed including water leaking of steam soot blower, dew point corrosion caused by steam, soot deposits in convection chamber owning to poor soot blowing, high flue gas temperature, no heat recovery of flue gas, and poor performance of insulation lining, etc. by using sonic soot removing system, flue gas recovery system, spray coating of fiber and rock wool, as well as adjustment of flow scheme accordingly in the technical revamping. the dew point corrosion is completely eliminated, the insulation performance is improved, the heat loss is reduced by 1. 25 %, the flue gas temperature is reduced to about 170, and the heater efficiency is increased from 83 % to more than 90 %
文摘:分析了金陵石油化工公司煉油廠二套常減壓裝置加熱爐存在的因蒸汽吹灰器漏水，蒸汽引起露點腐蝕及吹灰效果差造成對流室積灰，排煙溫度高，煙氣熱量未回收利用以及爐子保溫襯里效果差等問題，提出採用聲波除灰系統、煙氣回收系統、纖維噴塗和巖棉噴塗及相應的流程調整等改造措施.測定結果表明，本次技術改造解決了因蒸汽吹灰器漏水所造成的露點腐蝕問題，提高了保溫效果，減少散熱損失1 . 25 % ，排煙溫度降至170左右，裝置的爐效率由83 %左右提高到90 %以上The causes for low efficiency of the heater in no. 2 crude unit of jpc refinery are described and analyzed including water leaking of steam soot blower, dew point corrosion caused by steam, soot deposits in convection chamber owning to poor soot blowing, high flue gas temperature, no heat recovery of flue gas, and poor performance of insulation lining, etc. by using sonic soot removing system, flue gas recovery system, spray coating of fiber and rock wool, as well as adjustment of flow scheme accordingly in the technical revamping. the dew point corrosion is completely eliminated, the insulation performance is improved, the heat loss is reduced by 1. 25 %, the flue gas temperature is reduced to about 170, and the heater efficiency is increased from 83 % to more than 90 %
