How to connect self-generated medium-pressure steam to the grid at startup, and what precautions should be taken? Should it be connected to the grid before the compressor is started, or after it is started? Everyone is welcome to engage in lively discussions.
During operation here, as the system temperature rises, steam is gradually introduced into the equipment; therefore, under normal conditions it will simply merge with the pipeline network on its own, without any need for switching operations!
There is a dehydrating tank where the steam enters and exits. Before starting up each steam-generating unit, flush it with demineralized water until the proper liquid level is reached; then introduce steam to maintain both pressure and liquid level. The temperature rises in line with the heating of the system, and during this process regular sludge removal should be carried out to ensure good water quality! As the temperature rises, when the pressure exceeds that of the pipeline network, it will automatically discharge into the pipeline network and turn into steam! The advantage of doing this is that the operation is relatively smooth, preventing water entrainment and water hammer phenomena from occurring during normal operation!
