Testing with feedback, Step 9 of a DIY recordPosted: December 11, 2012
If last years burner was a vehicle it would have been a freight train, powerful and hard to throttle back. This new burner is a Jeep, dependable and at at this point slightly underpowered. The burner design will no doubt need to be tweaked but it was a great first day. As you can see the burner was having a hard time getting well lit. Those of you with a wood stove I am sure can relate. At about 118 minutes in the flames finally took over and the slope looks good.
The saw tooth effect you see up top is the result of the circulator pump turning on and off. I turned up the thermostat on the shop floor which has radiant tubes so this was a big load and it did not have the power to overcome the load. Although from the frequency change at the end you can see it was starting to catch up. But I am going to redesign the burner to direct the air flow a little better.
