Trying to diagnose some vibration issues here in a large Combustion Air Fan with a VFD driven electric motor. Bearings are oil lubricated rolling bearings. Frame is rigidly bolted to a concrete foundation and properly shimmed. Rotating frequency is 3042 rpm maximum, and rated frequency of 2982...
I have attached the PNID.
The coal crusher reduces the size of bituminous coal. The crushed coal is burnt in Furnace.
Bituminous coal is provided by external coal handling system and stored in 2 coal bunkers. From the silos the fuel is discharged by discharge though chain conveyors. The...
We have a coal hammer mill. It reduces coal size from 50 mm to 1 mm. We have been observing air on the top of the hammer mill and it feels like hammer mill is operating as a propellar?
Is it possible, if so, how to control it?
I have attached the PNID of the coal system.
We have a manual valve on this line as well. I want to optimize the flow, need the maximum flow so that I'm trying to quantify it first.
The flow values are to be quantified just for information and optimization.
The pipe opens into large surface area with cylindrical shape of 2m diameter.
The air is used to remove blockages from restricted area in Boiler house return leg.
ID of the pipe,
The ID is 16.45 mm
Length of the pipe
Pipe length from 50 DN header is 10 MTR till the discharge.
Pressure at or needed at the end of the pipe.
Pressure at the discharge is unknown. We are using this air to remove blockage of coal.
Does the header pressure change when the is...
Hello everyone,
I was wondering if anyone could help me with calculating the flow of air through a 12 DN SS pipe. The compressed air header is at 9.5 barg. I am not completely familiar with the calculations needed for this and would appreciate some guidance. Any advice or resources you could...
