The problem of drawer oil furnace tube perforation in furfural refining unit is analyzed. An urgent need the measure and effective settlement scheme are proposed.
The burning coke way of the furnace tube of the atmospheric distillation plant in small scale refinery was introduced. The views of attention in burning coke process were pointed out.
By material and crystal analysis of the swollen and cracked pyrolysis furnace tubes, summarizes reasons for the failure of the tubes, and proposes preventive measures.
The contrasting and analysis on every item properties of furnace tube that mostly used in pipe heating furnace at present, especially high temperature properties, has been done.
The weldability, repair quality and reliability of a furnace tube bear closed relation to the accumulated damage at microscale. Certain correlation between the hardness and damage could also be found.
The microstructure and creep process of HK 40 furnace tubes after different service duration were analyzed by means of micrography.
A model and a application model of coke laydown on inner wall of the coker furnace tube have been developed.
Failure Analysis And Countermeasure the blowout of furnace tubes in Propane Deasphalting Unit
Uses the ripple furnace tube , and the thread smoke tube, increased the heat transfer effect, enhances the boiler thermal efficiency;
It was found that repair of furnace tubes is difficult as damage rates are 4.5 or above. When damage rates are below 4.5, repair of furnace tubes is feasible.
The heating furnace tube is monitored by using the infrared. The trouble of tube is identified and diagnosed by analyzing the infrared thermogram, the temperature distributing and overheat appearance.
In the long-term operation of atmospheric and vacuum heat furnace that use vacuum heavy oil as fuel, thesurface of nailhead furnace tube in the convection chamber was seriously deposited.
By the analysis and experiment measurement of damage condition of HK40 furnace tube, it was regarded that the damage material had critical damage condition at the tip of crack.
The efficiency of renewal of furnace tube is increased.
When a reformer furnace tube locally failed, the whole furnace tube service life will be extended by replacing the failed furnace tube.
