Another shutdown, clogged flame retention head


Tonight the boiler shutdown. I opened it up and discovered the expected coked up flame retention head. I cleaned it with some acetone, a gasket scraper, a small wire brush and a flattened piece of 10 AWG solid copper wire. After 20 minutes of cleaning, I closed the door, started the boiler up again and had good flame.
We went from March 01, 2008 to today (March 17, 2008) before needing to clean. That is not really improved since the before the nozzle check valve and nozzle heater.
Next I will order a Delevan nozzle check valve and try that with a new Delevan nozzle. The two pictures on top are the "post" cleaning and the four pictures on bottom are the "pre" cleaning.
We will keep trying and monitoring.

Looks like barbeque sauce. Or maybe fried food that was left in the fryer for too long.

If you like, I can send you a sample, you can spread it all over your next tofu dish.

clearly you simply just pulled images from The Matrix and the back of Neo's (or whomever else's) neck for that socket-bioport-whatever thingy. don't insult your readers. (thanks for the vent. j/k)

lesson learned: in addition to anything-valve, other-stuff-nozzle also is important.
