In addition to the pressure of the steam supplied by the boiler, the hydrophobicity of the steam piping system is also important. This is because when the base paper and the single-sided paperboard pass through each preheater, a large amount of heat is taken away, so that part of the saturated water vapor is condensed into liquid water. This part of the condensed water must be discharged in time, otherwise it will affect the heating effect of the preheater.

In daily work, if the preheating roller using the steam head has a low temperature or a temperature difference of 5 ° C or more at both ends, it indicates that the suction pipe is damaged or the installation position is incorrect, and it must be disassembled for inspection. In general, the flow index of the trap should be 2 to 3 times that of the condensate. If the amount of water is not enough, the trap should be replaced. In addition, in the daily operation of production, should develop good habits, check the drain outlet of the trap every week, and find that the blockage should be cleaned in time.

During the start-up operation of the corrugated paper production line, the above parts should be inspected at any time and adjusted at any time. Only in this way can we guarantee the production of qualified products.
