Have any of you had any success in lowering the Silt Density Index (SDI) of your water with chemical injections, such as coagulants or dispersants, before it enters the Reverse Osmosis (RO) filters? We've tried one company, but we had no luck. We've also modified the filters to various sizes...
Can you explain how I should take this into account? The fouling resist. are low, about .0005.
I was considering having pressure guages installed on the 3/4" bleeder valves to give an idea of pressure drop.
We don't have any inlet/outlet points for flow either. Is it okay to use the original...
IF ANYONE ELSE COMES ACROSS THIS PROBLEM HERE IS MY SOLUTION:
I’ll tell you what I’d do. On the original spec sheet for the exchanger you should find the design heat transfer coefficient (U) and the surface area of the tubes. The heat transfer coefficient is the best way to tell how well the...
Hello gents,
I'm an intern and I've been tasked to run an analysis on our heat exchangers. We have HXs that are 1 pass and 2 pass exchangers. Water-to-Water and water-to-seawater. How can I calculate their efficiency/performance based on original design specs?
I have inlet/outlet temps...
Our isolation valves cannot fully stop the steam from getting to the steam turbine (combined cycle plant). At around 40psi, the MWs drop or jump by 10-20 MW within a second. I think it is a crack on the stem of the control valve. Could it be something else?
Is there anyway to fix this...
I work at a combined cycle plant and we also send steam to 2 hosts. Where can I get information or how can I calculate the heat rate when taking this into consideration?
How can I calculate the GE-7FA's HRSG efficiency? Total unit efficiency (compressor+Turbine+HRSG)?
I have calculated the compressor efficiency and the thermal efficiency.
Also, how can I calculate the Steam adjusted heat rate? Or what resources should I use to figure this out?
I appreciate...
