Pulverized Coal Flow Measurement Testing Requiremetns
Pulverized Coal Flow Measurement Testing Requiremetns
(OP)
I am an engineer at a fossil fired boiler power plant. We are redesigning the coal nozzles for lower NOx. The units in question are equipped with CE Raymond Bowl Mills (RB-533) and B&W MPS-67 Pulverizers. We have hired a testing outfit to perform an isokinetic coal flow test on the coal piping risers after the mills. I am not that familiar with the testing code that governs this and I don't have a vast PTC ot ASME library. My questions:
1. What are the upstream and downstream straight pipe requirements for the test ports?
2. Does a victaulic coupling qualify as a disturbance?
3. Is a gate valve wide open a significant disturbance?
Thanks.
