Sod Peat or Milled Peat?
Peat is a multi-use biofuel, which can be utilised in the heat production of small houses as well as in big power plants. The heating target determines which peat is better. Milled peat is suitable for large-scale power and heating plants. Sod peat has many more possible uses.
Peat weighs more than wood chips, and it is good to take this fact into account when rationing the fuel manually into a burner. If the consumption of peat is great, it is advisable to get a system with an automatic extractor. This saves a lot of manual labour.
Multi-Purpose Sod Peat
Sod peat can be used as well in small-scale heating targets as in large heating plants. It is an affordable fuel and of uniform quality. Suitable heating targets are for example farms, greenhouses, and detached houses using a stoker burner. Sod peat is prepared especially for smaller heating targets.
Sod peat has a relatively high heat value. One loose cubic metre of sod peat has 1,4 MWh energy. Burning peat mixed with wood-based fuels decreases the corrosion of boilers. Corrosion usually occurs if only wood-based fuels are used.
The ash content of peat is 4–6 %. Compared to that of wood’s, 0,5 %, it is high. This fact is good to be taken into account, but it is not necessarily a very offending factor.
Sod peat in a nutshell:
- energy content approx. 3,6 MWh/tonne or 12,9 MJ/kg
- diameter 40–70 mm
- length 50–200 mm
- moisture content 25–40 %
- weight 350–400 kg/loose cubic meter
- ash content 4–6 %
