Regarding steam flow rate calculation
Thread Content
Saturated steam is used in the facility. 16 kg is reduced to 3 kg and 8 kg by adding water, lowering temperature, and reducing pressure, measured in T/h. The problem now is that the flow rate at 16 kg does not match the flow rates at 3 kg and 8 kg. All measurements are carried out using orifice plates combined with transmitters. According to the process, at 16 kg, there is 15 T/h of steam; after adding 2 T of water, the amount drops to 3 kg. At 8 kg, the value should be around 17 T as well. I want to ask if this calculation is correct?
It’s possible to have too much water, resulting in inaccurate measurements
What is being measured is the mass flow rate; adding 2 tons of water results in an increase of just over 2 tons, so the process description is correct. However, the cumulative flow rate should be considered; the instantaneous flow rate changes too rapidly, making it difficult to determine whether it is correct or not...
Theoretically, it should be like that. But after spraying water, it might be humid air. Plus, the inaccuracy of the flow meter. The error is larger then.
