Can someone point me to steam nozzle photo - not sure what it is? I'm sizing a 100HP 150 psi steam boiler for a process and the manufacturer recommends a 2-1/2" steam nozzle.
The boiler comes with a 4" flanged supply connection & thought I would use a 4" stop check & OSY valve. Is the nozzle...
Here's what I found from Armstrong:
Thermodynamic Disc
The disc type of trap is a time cycle device. As soon as the pressure above the disc is dissipated, the trap will open. It cycles whether or not there is condensate behind it. Since very little condensate will be present even at the trap in...
I contacted a few superheater manufacturers and none were very reassuring. I requested sales literature or piping diagrams but nothing is available on the drain piping.
I am designing a 150 psi natural gas fired steam boiler with an electric superheater raising the delivery temp to 600F.
The horizontal electric superheater has a 3/4" npt drain at the bottom of the vessel.
Any suggestions on how to handle the drain? Bucket trap to vented receiver then waste to...
I struggle with Plant Operators all the time on this very subject. My projects are located in Northeast US.
Bringing moist, humid air into the plant during the summer is not a good idea. One area which is a problem is the pipe gallery underneath the filter banks. If the ventilation fans...
I am a HVAC engineer working on an exhaust design project for a water treatment plant. The plant is having air quality issues with chlorine odor in the filter bed gallery. Workers at the plant are complaining about sore throats after a full day work.
We are planning on building enclosures to...
Does anyone know of any good books for water treatment / wastewater treatment plant ventilation design?
These buildings are simple yet very complicated from a ventilation standpoint. Chlorine odors, high humidity below grade in pipe galleries, etc.
I am having a hard time convincing plant...
The water temps will fluctuate based on groundwater temperatures. There is little air movement in the space.
I'm asked to evaluate the insulation properties of the enclosure to determine if condensation will occur.
So, if no outdoor air is introduced you think the Wet bulb of the space will...
What is the resulting RH of air in a warehouse heated to 50-55F with a 35F open tank of water?
Knowns:
Building is 200x200
Open tank is 100x100
Ambient Outdoor 10F/20%RH
Indoor 50-55F
RH of Air?
Underground garages have no sizing codes. Be careful with local inspectors interpreting the need for oil interceptors. Around the Chesapeake Bay Maryland & VA they are concerned with oil getting into the storm system.
Just run 4" system to 4" drains. In the NE, many building owners are...
Where do you account for the antifreeze losses in GSHPCalc software?
If you have a 300 ton system load you need 300+ tons of cooling due to the antifreeze i.e. more wells required.
Or should I try to get my load calc program to account for the additional antifreeze load?
I am working on a LEED water treatment plant project. According to ASHRAE 90.1 the process areas are semi-heated (less than 15 BTU/hr-ft2 Zone 4) spaces and the office areas are conditioned.
When preparing the simulation model, I'm thinking the envelope should be broken into 2 values. One...
So you are saying that bare sanitary drain piping is not permissible in an open parking garage? You think that the pipe should be insulated. This is contrary to all of the installations that I've designed in the past. Also, I never saw this in any of the parking garages I've been in.
