18kw electric steam generator for pharmaceutical

In addition, the steam in the direct steam delivery pipe that has not been heated will condense at once, which will generate local low pressure/cause the steam to carry condensed water to impact to the low pressure place, and water hammer will deform the pipeline, damage the insulation layer, and the situation is serious. Sometimes the pipeline can be broken. Therefore, it is necessary to warm the pipe before sending steam.
Before heating the pipe, first open the various traps in the main steam pipeline to discharge the condensed water accumulated in the steam pipeline, and then slowly open the main steam valve of the steam generator for about half a turn (or slowly open the bypass valve); let a certain amount of steam Enter the pipeline to make the temperature rise slowly. After the pipeline is fully heated, then fully open the main steam valve of the steam generator.
When multiple steam generators are running at the same time, if the newly put into operation steam generator has an isolation valve connecting the main steam valve and the steam main pipe, the pipeline between the isolation valve and the steam generator needs to be warmed up. The warming operation can be carried out according to the method mentioned above. You can also open the main steam valve of the steam generator and various traps before the isolation valve when the fire is raised, and use the steam that appears during the boosting process of the steam generator to heat slowly. .
The pressure and temperature of the pipeline are increased due to the increase in pressure and temperature of the steam generator, which not only saves the time for heating the pipe, but also is safe and convenient. Single operating steam generator. Such as the steam pipeline can also use this method to do the heating pipe soon. When heating the pipe, once the expansion of the pipeline and the abnormality of the support and hanger are found; or if there is a certain vibration sound, it indicates that the temperature of the heating pipe is raised too fast; the steam supply speed must be slowed down, that is, the opening speed of the steam valve should be slowed down. , to increase the warm-up time.
If the vibration is too loud, turn off the steam valve immediately and open the large drain valve to stop heating the pipe, and then proceed after finding the cause and eliminating the fault. After the warm pipe is finished, close the steam trap on the pipe. After the steam pipeline is heated, the steam supply and furnace can be carried out.
