I played hookie today just cause. So I decided to work on the boiler project and get my new coil done. I have a little bit on it to redo (I did a small oops) but it is all together right now and working. I have done 2 test runs and I am Happy! This new coil kicks some seriuos butt. I ran everything the same as all my other tests except, this time I didn't insulate the steam line.
So, running 1 qt/min and at max fire I brought 6 gallons of 50* water to a boil in only 20min.
After letting it run a little while, I wanted to see it maintain a boil with no lid and it did. So I shut off the fire and let the water run to see about how well the coil would chill the water down. In 4 min I hit 149* but shortly after it kinda stalled at 130*. Now I didn't let it run for very long. I stopped running water through it after 8min. I wanted to see how long it would take to boil again from a higher temp. Trying to simulate a sparge situation. I also removed the insulation from the pot on this run and it boiled again from 120* in 14min.
That might seem a little odd but the first several degrees of increase are extremly fast. Starting at 50* it only took 5min to get to 103*.
Here is a teaser of the new coil I made. This one goes in the top and out the bottom. It is 1/4" tubing and has 4 10' coils.
Edit: I just deleted my videos cause they were freezing up my internet. I don't know why they would do that. I got rid of all three I had. Any ideas on this?
