What should be the nitrogen protection pressure for the electric capture insulation box?
Thread Content
As the title says. The nitrogen pressure in the electric capture insulation box at our factory is 0.4 MPa. We now want to reduce the amount of nitrogen used; we plan to install a pressure reducing valve, but we’re not sure what pressure level should be maintained, nor which model of pressure reducing valve to choose. Anyone who is familiar with this topic please offer some guidance
We control the flow, not the pressure. The flow rate is 80-100 cubic meters, and the equipment is operating perfectly fine. We once ran out of nitrogen for a month due to an air separation failure; as a result, the 4 electrostatic precipitators experienced 5 failures. Nitrogen is very important. If you want to save nitrogen, you can also use gas that has been purified and heated to 90-100 degrees; although no one has been known to use it, most people consider it feasible. However, safety measures must be properly implemented.
