When a waste oil incinerator was in operation exhaust gas high temperature alarm(at1200°C)sounded.The incinerator operation was immediately stopped and a check was made it revealed smoke coming from overheated paint on the back side of the incinerator casing threatening to develop into a fire in the engine room.
當廢油焚燒爐運行時，排氣高溫警報(1200°C)響起。 焚燒爐立即停止了運轉，并進行了檢查。發(fā)現焚燒爐背面外殼的油漆過熱產生了煙霧，進一步發(fā)展可能導致機艙起火。 (1)Scorched paint on the rear side of the casing(Photo1) (2)Bottom part of the air-cooling duct clogged with deposits ofThe furnace casing was cut open and after the solid sludge was re moved,the furnace casing was restored.The following precaution- ary measures were taken after the accident;打開爐膛，清除固體污泥后，恢復爐殼外觀。 事故發(fā)生后采取了以下預防措施; ：(1)Made an inspection/cleaning hole at the bottom of the backside of the cooling duck(Photo 3).(2)Disseminated an outline of this accident and instructed relevantvessels to inspect inside of cooling duct.Because the clogging of cooling duct was reported from more than 50 % of owned ships.(3)Inspect this part once every monthand include it in the periodic maintenance plan.（1）背面底部檢查/清潔進風口，如圖3，冷卻風道的側面； （2）通報事故情況，因超過百分50的船舶報告?zhèn)让胬鋮s風道因積碳阻塞；（3）每月檢查一次，并將此部分列入定期維護計劃 ； The accident is attributed to the blockage of the air-cooling duct with deposits of sludgeThe ductthough fitted with a drainpipe was not provided with an inspection holewhich inherently pre vented itsinternal inspection. 本次事故主要原因是由于側面風冷管道淤積的污泥堵塞造成進冷卻風受阻。風冷管道雖然裝有排水管，但沒有設置檢查孔，這本身就妨礙了內部檢查。
經驗教訓：每次用完焚燒爐，務必及時清除內部垃圾，特別是底部或側面的進風口要注意清通。
