120kw Electric Steam Generator

In addition, the steam in the steam pipe that is not directly heated will condense when it encounters local low pressure, causing the steam to carry condensate and impact to the low pressure. Water hammer will cause the pipe to deform, shock and damage the insulation layer, and the situation is serious. Sometimes the pipeline can crack. Therefore, the pipe must be warmed before sending steam.
Before heating the pipe, first open various traps in the main steam pipe to drain the condensed water accumulated in the steam pipe, 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 and slowly increase the temperature. After the pipeline is fully heated, 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. The pipe heating 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 started, and use the steam produced during the steam generator boosting process to slowly heat it. .
The pressure and temperature of the pipeline are increased due to the pressure and temperature increase of the steam generator, which not only saves the time of heating the pipe, but is also safe and convenient. Single operating steam generator. For example, steam pipes can also be heated using this method soon. When heating the pipes, if it is found that the pipes are expanding or there are abnormalities in the supports or hangers; or if there is a certain shock sound, it means that the heating pipes are heating up too quickly; the steam supply speed must be slowed down, that is, the opening speed of the steam valve must be slowed down. , to increase the heating time.
If the vibration is too loud, immediately turn off the steam valve and open the drain valve to stop heating the pipe. Wait until the cause is found and the fault is eliminated before proceeding. After warming the pipes, close the traps on the pipes. After the steam pipe is heated, steam can be supplied and combined with the furnace.
