Guide to Ceramic Sponge Wool Use in Bioethanol Burners

Guide to Ceramic Sponge Wool Use in Bioethanol Burners

When I was designing bioethanol fireplaces one of the problems I noticed was that the burner tray would naturally get hot during the operation of the fire and this in turn caused the fuel to vent off faster than it was being burnt. The problem also existed when the burner was shut off. This causes the running costs to be exaggerated. Read my guide to bioethanol fireplace running costs for more details on that subject. The solution I found was to use ceramic wool fibre matting in the burner tray.

However, note this cannot be any old foam or sponge, it should be properly approved for use with a bioethanol burner tray. Read the sellers instructions and confirmation that what you are buying is suitable for this application.

Advantages of using the Ceramic Sponge In Bioethanol Burners

Here is a summary of what advantages I noticed when the bioethanol fireplace ceramic wool is used in a burner tray.

  1.  Reduces the capacity of the tray to a safer level.
  2. Extends the running time and therefore reduces the cost of using the bioethanol fireplace overall.
  3. Reduces the amount of fuel that vents off due to heat and again this reduces cost.
  4. Improves the safety as the fuel is absorbed by the sponge. This is most effective when using a portable fire for example a table top bioethanol fireplace or outdoor bioethanol fireplace. If no ceramic sponge wool is used any unburnt fuel will likely get spilt when the fire is moved. This will be dramatically reduced with the ceramic sponge in the burner.
  5. The flame seems to be more stable.

Ceramic Sponge Wool and Gel Fires

Personally, I would not use the ceramic sponge with gel fuel, only bioethanol fuel. There is a difference to how the gel fuel and bioethanol fuel burns, if you are unsure read my guide to the differences between bioethanol fuel and gel fuel.

Where to Buy Ceramic Sponge In Bioethanol Burners

There are a number of suppliers available online offering the ceramic sponge wool specifically for this application. Also, at the cost of not much more than a couple of bottles of fuel you can reduce the overall fuel usage. Most suppliers offer a specific size that can be cut down using scissors (wear gloves when you handle the wool). Measure your burner tray.
