The venturi outlet temperature is high; what could be the reasons?
Thread Content
In our sulfuric acid plant, the temperature at the inlet of the venturi is now 170°C, while it drops to 72°C at the outlet. Previously, the inlet temperature was over 200°C and the outlet temperature was only 50°C. The instruments have been checked, and the acid pressure on the pump is 400 mm.H2O. May I ask what other issues can cause a high temperature at the venturi outlet?
1. Detect system load； 2. Is the moisture content of the raw materials too high, or are there faults in previous equipment (such as boilers)? ； Increase the spray volume appropriately.
The main things to check are the nozzle of the reverse jet nozzle and the water flow rate
