Summer’s almost over, time to start thinking about heat

2013 Boiler design flow chart

I know it’s early on the calendar but my focus is starting to shift back to my heating hobby.  After two years of experimenting I have a proven performer with both the mechanical unit and the software I used last winter.  I could change nothing and go through the winter fairly smoothly but there is  always room for more improvement.   So this is my plan:  1) Build a new unit very similar to the proven unit I have been using but with greater feed range capability to allow the unit to feed wood chips as well as pellets.  By building a complete new unit I can always roll up the proven unit after the experiment is over and the data collected and resume heating without a hiccup.   2) Make slight modifications to the boiler to allow a larger interface plate between the feed unit and the boiler.  This will allow a greater range of experimentation with burner designs.  3) Continue making small experimental changes to the working pellet unit such as a vibrator for ash removal, different burner designs, different draft designs.  4)  Continue to make changes and improvements to the software.  To start I would like three modes of operation.  Continuous, run for some amount of time, and run until a set time.  I changed the software to run to a set time by calendar date last spring but it was built into the software by date not menu or button choice.  I would like to have the option of running for a few hours for both experimentation and also to occasionally heat hot water and be able to choose these options by menu.  This fall I am sure I would like the unit to be able to take the chill off and then shut down.    5) Build a chip dryer.  This is going to get to be a priority , I know the days are getting a little shorter and it is amazing how much less solar there is in the fall.  Time to giddy up on that one.

I know I have to prioritize the work, and work as time and cash flow allows.  But I think the first step will be to make a new interface plate and boiler opening.  This will allow standardization for the next design and this work can be done while there is no particular need for heat.  I went dumpster diving the other day and got a great new electrical box, so I guess I can get going on the that part of the new burner feed.  I like free stuff.  I may hit that dumpster again soon.

In the mean time it is still summer and there is still sailing weather.
