As a result, nutrient-rich additives such as manure, urine and food waste are used to enhance and accelerate the process.
One of the most common application of biological wood oxidation is in a compost heater or "Biomeiler".
Now, it has been developed in Germany.,[1] Romania,[2] Netherlands,[3] Australia and some other countries like Italy, France, US, Belgium, Czech Republic.
These coils are completely filled with water, which runs through a heat-exchanger mechanism, like a radiator.
The percolated water is usually collected on the bottom of turbomeiler and flowed to a buffer tank for heat recovery.
[3] The next advantage of biological wood oxidation is that it is an environment-friendly technology and can reduce the environmental pressure caused by combustion of fossil fuels.
With the rapid increase of worldwide energy demand, the generated heat from biological wood oxidation gains more and more interests, as it can be seen as a sustainable alternative to fossil fuels and one of the primary possibilities for preventing global warming [13] The main disadvantage of biological wood oxidation is that the heat production rate is low and it is not possible to drain enough hot water for a longer period of time.
[17] In order to get a reasonable hot water service, the pile mass of biological wood oxidation is usually large.
Biomeiler is a big pile of woodchips and its core part has low rate of air exchange.
Biological wood oxidation is an aerobic process, which is strongly inhibited by the low oxygen availability.
[22] The temperature in the outside part of biomeiler may be low because the generated heat is likely lost to the ambient air.
Tons of water is initially added to the biomeiler pile in order to wet the woodchips.
However, it was reported that the maximum temperature of turbomeiler is only 37 °C due to the poor insulation condition.
