The temperatures in the biomeiler pile are measured with thermocouples buried in several locations. Nine of them are found at three heights (1’, 2’, and 3’ above the ground) in the inner core, outer core, and mantle of the pile. The graph in today’s post shows the temperatures measured by thermocouples at 2’ height. These […]

The graph shows the temperature in the chicken coop, the temperature of the air in the vent pipe coming from the biomeiler, and the temperature of the outdoor air. The electrical energy usage is shown for any days when the electric heater was used. The scale is the same, but the units are in kWh.

While running the compressor to aerate the biomeiler pile, I noticed that the back pressure was unusually high; about 30 psi. Typically, the gauge reads about 5 psi. Yesterday, the reading was about 12 psi, but that wasn’t unusual enough to catch my attention. I looked for kinks in the hose, but found none. My

The temperature readings in the pile have been puzzling me. Today, I’ll describe how I have tried to improve matters. While doing the morning chores, I run the air compressor to aerate the biomeiler pile. I expected that the internal temperature would increase after the recent upgrade to the aeration system. There should now be

After purchasing the parts to upgrade the aeration system, the temperatures have been high enough that the tire valve and clip-on chuck have functioned with no troubles. That temporarily removed my motivation to make the planned upgrade. This is the tire valve fitting I made for a soda-bottle-rocket launcher. It was repurposed to make the

Our luck ran out. The recent cold spell lasted long enough that I had to turn on the electric heater in the coop. The temperatures were in the -20s, with the coldest recorded temperature being -29F. The fresh air coming in through the pipe that coils inside the biomeiler is still reading 32-37F, but the
