Burner cooling water inlet and outlet flow
Thread Content
It is found that the inlet and outlet flow rates of the burner cooling water are inconsistent. The inlet and outlet flow rates of some burners differ by about 2 square meters. Is this normal?
It's normal, the measuring instrument also has errors.
Burner cooling water is an important indicator. If you want to judge whether the burner cooling water coil is burned out, you need to refer to the displays of several other instruments.
If it's 2 cubic meters, I think it's normal. Our company only jumped when the difference was 8 cubic meters.
Is the return water flow 2 cubic meters lower than the inlet flow? If there is no change in the outlet temperature, it should be normal. Because it is difficult to avoid bubbles in the general return pipe.
Just looking at the flow rate will be misleading. You should also refer to whether the liquid level in the water buffer tank has changed.
I agree with what was said above. You can't just look at the flow difference. If there is a buffer tank, you can observe the liquid level changes in the buffer tank. You can also observe the temperature of the nozzle and the pressure of the inlet and outlet water.

In addition to the instrument error, another reason is that bubbles will inevitably appear when the burner cooling water passes through the cooling water coil. Most of the flow meters we use are pressure differential flow meters. This flow rate is only suitable for single-phase fluids. The pressure difference flow curves corresponding to different phase fluids are different. If bubbles appear in the burner cooling water, the flow meter will definitely have errors!
