I want to run new cooling water supply and return headers for a few air compressors. Headers will be taken off very large CW supply/return plant headers.
I have sized the supply header to the compressors.
Is it recommended to increase the return header diameter by one pipe size to promote...
1250psig 900F superheated steam is routed from a main to atmosphere through an 1-1/2" line. The line is about 150ft long with (3) 90's. How can I calculate the maximum flow to atmosphere?
thanks.
I have several traps that are running in individual lines to a vented receiver tank. I would like to combine the discharge of the traps into a single line that goes into a new vented receiver tank.
The traps are all operating at varying upstream pressures..30psig, 175psig, 400psig, and...
Hello,
I want to pipe the discharge from some steam traps to the bottom of a condenser that is maintained at about -27inHgA.
Since the condenser connection is only 10ft(net) higher than the trap, I believe the condenser vacuum will be able to pull the condensate from the trap without any...
I have a small blower that is taking coal dust from a rotary airlock and blowing it into a bunker. I know blower hp, rotary airlock rpm, blower rpm, cfm, pressure, density of coal dust, and conveying line size. Is there a way I can calculate/estimate performance?
Thanks.
I want to calculate how much gas we would need to burn to heat the water in the package boiler up from ambient to 375F.
Can I just assume that I'm only heating the water at the boiler efficiency provided by the manufacturer? Or do I need to take into account the heating of the tubes, drum...
We have a package boiler that feeds saturated steam into a common header that goes to process. There are two manual block valves right off the steam drum, but no non-return valves. There is a coal-fired boiler that also feeds into this header via a turbine. There is a control valve (with...
Hello,
I have snuff steam lines running to coal bunkers (mixture of IL and Western coal) and would like to verify that the lines are adequately placed and sized.
Does anyone know of references on the web that could provide information such as how much steam needs to flow in what period of time...
Hello,
I have snuff steam lines running to coal bunkers and would like to verify that the lines are adequately placed and sized.
Does anyone know of references on the web that could provide information such as how much steam needs to flow in what period of time to fight a fire in a coal bunker...
Assume ammonia vapor at 100F, 100psi, in a 3" SS pipe. Assume pipeline is very long and is connected to a bulk tank (also at 100psi, 100F) with an unlimited quantity of ammonia.
Now assume this pipeline breaks. So you have a 3" line that is vented to atmospheric. How can I calculate...
I have 1250psi superheated steam as supply to a turbine. There are 400psi and 175psi saturated steam extraction lines coming off the turbine.
Which steam traps are best for the drip legs on each line? I am leaning towards sarco thermodynamic traps for all lines but the bucket trap looks...
Hello,
I am injecting approx 100gpd of 36% muriatic HCl into a 16" 316SS line. 3750gpm of water is flowing through the 16" pipe.
I am looking for an injection quill that can easily handle the HCl as well as vibration in the pipe. Plastic/PVC/teflon/etc are not desirable. I prefer an...
I have a vertical turbine pump that puts out too much head for the application. Is it advisable to partially close a manual butterfly valve on the discharge side of the pump to create a pressure drop?
Thanks.
Hello,
I am looking for 12" PVC bell/spigot pipe for a fire main project. Pressure rating needs to be 250psi.
All I can find is C-900 and C-905 pipe which is rated for 200psi. The pressure rating only jumps to 250psi in 14" or larger diameter.
Anyone know of a vendor/manufacturer...
I am planning to install a loop off a fire main to service a firehouse for a cooling tower. Most of the loop will be plastic bell and spigot. However, I plan to change to S40 304SS under the building and closeby to reduce possibility of leaks under the building.
The pipe will 90-up into the...
We have concentrated bulk HCl storage on site. We also have a supply and return HCl header that is always pressurized. What is the best way to setup acid injection on the RO feedwater line?
I thought about using a daytank that operators could fill once per week and would draw down and get...
Hello all,
Our water treatment company is touting the benefits of a chlorine dioxide generator (from sodium hypochlorite, chlorine, and sulfuric acid). I think it's because they're going to make more money off of it rather than what's good for us necessarily.
I'm also considering the...
I have a 30' diameter carbon steel tank, approx 37' high. Acidic water has been stored in this tank in the past so there is substantial pitting. The tank has a fixed roof and is always at atmospheric pressure. I have UT'd the tank in several spots.
I would like to know how much water I can...
We have a safety relief valve on our 175psi steam header. The discharge of the relief valve is piped through the building and up through the roof. A drain leg w/ temp probe and control valve is piped to the floor.
I assume whoever installed this setup thought that as condensate cooled below...
We have 3 reverse osmosis units, each fed by a 200hp centrifugal pump capable of approx 1600gpm @280' head and 150psi. The actual vertical run between the pump and the inlet to the RO units is about 30'. I have verified the head/flow requirements and we're ok there.
There is a 6" V-ball...
