Commissioning of steam condensate system
Thread Content
In such a situation, the condensate from the steam heater is first buffered in the flash tank and then merged into the condensate main pipe. How can such a steam condensate system main pipe be put into use? Does it need to be heated before being merged into the condensate when the pipe is empty? How to warm it? Thanks!
Before the condensate is merged into the main pipe, the condensate is discharged locally because of the low temperature. When the condensate temperature is close to the temperature of the condensate main pipe, when the condensate reaches 140 degrees, the condensate can be merged into the condensate main pipe. Before merging into the main pipe, the valve from the flash tank to the condensate main pipe must be closed and the valve opened. The backwash between the liquid main pipe and the condensate control valve of the flash tank, warm the pipeline between the flash tank and the condensate main pipe, close the backwash after completion, then close the backwash for on-site discharge of the condensate, and then connect the flow of the flash tank and the condensate main pipe. One key point is that it must be turned off first and then turned on to prevent cross-voltage.
The 2nd floor made it clearer, I’ll add a few more: The condensate from the steam heater is first introduced into the flash tank for buffering, the flash tank is preheated, its inlet and outlet pipes are warmed, and the flash tank outlet diversion valve is discharged locally (recycling is better! ). After the temperature of the condensate discharged from the diversion valve rises (observation with the naked eye indicates that there is more steam in the condensate flashing), it can be directly merged into the condensate main pipe.
OK, thank you! But if there is no condensate in the main pipe, there is no way to use the hot condensate in the main pipe to preheat the pipe between the buffer tank and the main pipe. What precautions should be taken when merging? Is it necessary to use steam from elsewhere to preheat the main pipe? In other words, this condensate is the first user merged into the condensate main pipe in time. This post was last written by lianhua * Edited by aoqu on 2009-2-3 22:48 ]
If the main pipe is empty, steam condensate can be used to pass into the main pipe when the commissioning conditions are reached. If the temperature is not high, there is no need to heat the pipe.
Heat the water to prevent water hammering?
Can it be understood that after the condensate in the main pipe is drained out, the condensate is directly incorporated and the condensate is used to directly warm the pipe?
