Basis for time design of oxygen timeout interlock
Thread Content
doubt: 1. The actual measurement of valve action time is still given in the valve manual. Is the actual measurement significant? How long does the existing design take? 2. How to calculate the actual measurement of the furnace head pipeline (whether the burner diameter change and flow direction change are taken into account), especially the selection of the orifice plate aperture of the coal slurry circulation line. 3. Due to the rapid decrease in resistance flow after oxygen enters the furnace, can the hand valve behind the vent pipeline be closed to alleviate the problem? How to avoid the oxygen pipeline brushing caused by contamination of the vent pipeline? 4. There are so many issues with the design of the feeding and purging oxygen pipeline time in various places. Please correct me.
It is indeed a bit naive. The valve action time must be calculated by measuring the reducing diameter of the burner pipe in person. Don't forget the burner section. Oxygen enters the furnace, which is set by logical sequence. The patent company will tell you the purge time, which is determined by the patent company.
