blowing wool
1.When remembering blowing wool, every leg should be used a new razor blade and on the shave of full amount must cream, smear body latex wants to come after blowing wool moist the skin that just had been to cutin, cream after the beard that also can use a man will reduce the skin to be mixed aglow precautionary fine hair on the human body grows inside the skin.
2.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%.
