We operate a 1315 psig HRSG 24/7. We'd like to send the continuous blowdown from this HRSG to a standby package boiler (320 psig A-frame)). This blowdown will help keep this standby boiler warm.
I'd appreciate any information in regards to the injection of the blowdown water into the standby...
We've never used this brand of valve, and the quotes we have for them are considerably less than others (so this raised a red flag). But these also have a short delivery. Anybody out there with experience, either good or bad, with this brand of valve? They are sold by Newdell Company out of...
When the duct burners are NOT lit, HRSG flue gas occupies the volume inside of the burner piping. On the outside of the boiler where the fuel piping is subject to the ambient temperature the moisture in the flue gas condenses. This creates rust and clogs the burners and pilot gas lines...
When our back-pressure turbine is down, we must send the HP steam from our boiler (1315 psig, 905 F) through two steam conditioning valves to feed the two steam headers to the plant. One steam header operates at 145 psig/380 F and the other at 280 psig/ 480 F.
We are using BTG (now CCI) brand...
I am not a refrigeration guy, but I overheard an engineer in another section talking about purchasing another chiller for his section. The one he is getting consumes 935 kW to get 1200 tons of chilling. This is a COP of about 4.5. I'm no expert, but I am under the impression that a COP of 4.5...
I realize when most people talk about the dewpoint of their instrument air they are assuming the dewpoint measurement was made at line pressure. This is the pressure dewpoint.
I currently have our dewpoint analyzers set up to measure the dewpoint at very low pressure, then I do the conversion...
