How to Probed Examine the Operating Level of a Heater

Prodution practice has shown that, in the general economic examination target tor long crude oil pipeleine, it is not quit reasonable to take kg/10⁴t·km of fuel ucon-sumed to pipeline 10, 000 tonns crude oil as far as one kilometer as the fuel consumption target to be examined Citing the data obtained in operating practice, the article expounds the problems involved in taking the energy consumption value as an examination target. For example, the pump station with a lower energy consumption value is not high in its heater effect; in different months at the same station, it is quite similar in heater effect but different in energy consumption value; too little an energy consumption value will make the average heat effect of heaters deviates too far to be true; in the case of the different intervals, it is the same in energy consumption value, but quite different in transport distance. All these mentioned above are questions worth consideration. Therefore, the article suggests that the quantity of fuel consumed to make the temperature of 10, 000 tonns of crude oil rise by 1℃(kg/10⁴t·℃) be taken as the fuel consumption quota for a technical and economic target; and makes some explanations of such problems as to how to set the quota and have it carried out, and what to pay attention to. It is pointed out in particular that this proposal especially shows its comparable advantages in such long pipelines as running underload.
