@ February 23, 2013 10:51 PM in Question about pro pressI once crimped 2 sides of a tee, and then couldn't reach the bull because of ductwork.
After scratching my head a little, I pulled out the rubber, wrapped a wet rag around the fitting, and soldered it together.
Still don't like the stuff though.
@ February 23, 2013 10:48 PM in Question about pro pressThe consensus in our outfit is that it is a crackerjack shutdown tool, but for a full installation is awful. Every time you crimp a fitting it pulls the joint out of line, and if you have to make a change for any reason, you have to throw the old fitting out. Sure, it cuts down on the time it takes to train a guy, but do you really want someone so inexperienced that he can't solder pipe doing your work without supervision?
@ February 21, 2013 9:30 PM in Coal- the cleanest fuel source for steam heat? See linkReal, yes, but a long way from being feasible yet.
@ February 21, 2013 9:28 PM in Coal- the cleanest fuel source for steam heat? See linkIf you search the topic, you'll find that the method actually still produces the same amount of CO2, just in a manner that is easier to capture. Which is great, but now what do you do with the CO2? Impressive science, and it sounds like it would help deal with some of the nastier pollution problems like acid rain.
@ February 19, 2013 7:34 PM in Clean Steam generatorHumidifier panels have two steam ports- one for humidifier steam (which could come from a separate source) and one to run a small heat exchanger that guarantees that all the humidifier steam is evaporated. It's the second one that creates the condensate. In our case all this steam is generated from softened water at the (power plant) steam powered steam generator. I am worried about sending back the untreated water from a source outside of the boiler feedwater system. Even if it works in practice, the theory bugs me.
@ February 17, 2013 9:02 PM in Clean Steam generatorWe are building a new mechanical room in a hospital, and using power plant steam (90 psi) to generate clean steam (15 psi) from softened water with Aerco steam generators for humidification. We are using Dristeem Ultra-sorb Model XV steam dispersion panels in the ductwork. The panels produce condensate, which our engineer has us collecting and sending back to the power plant along with the regular condensate. Is this a good idea? I would think it would throw off the power plant water chemistry.
