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 % 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,提出采用聲波除灰系統、煙氣回收系統、纖維噴涂和巖棉噴涂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

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,提出采用聲波除灰系統、煙氣回收系統、纖維噴涂和巖棉噴涂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

According to disadvantages of common ( mineral ) wool rock plate for indoor flase ceiling , the company develops reinforced ( mineral ) rock wool powder coated steel sandwich plate for false ceiling ( also applicable for partition of wall , insulation material employs paper ( aluminum ) honeycomb 針對普通(礦)巖棉板的室內吊頂的諸多缺點,窩公司開發了系列加強型(礦)巖棉彩鋼板夾心吊頂用板(也可適用于墻體隔斷,芯材也可用紙(鋁)蜂窩。

High - strength rock wool board : used for various high / low temperature conditions , with good weight - bearing ability and compression - resistance , specially suitable for heat preservation and heat insulation for large ships , tanks , ovens , pipelines and other industrial facilities 高強度巖棉板:適用于高、低溫的各種條件下,有著很好的承載、抗壓特性,尤其適用于大型船舶、容器、烘箱和管道及工業設備的保溫、絕熱。

The operations of insulation division include glass wool tel process , rock wool , sound proof , special ceilings , and insulating foams which are developed in partnership with major chemical companies 隔音保溫材料部的生產始于1936年,是玻璃技術發展的產物,但更專業于保溫和隔音材料,產品包括:玻璃棉巖棉隔音天花板特殊天花板及發泡保溫材料。
