An experimental investigation of the combustion performance of human faeces

View Article: PubMed Central - PubMed

ABSTRACT

Dry human faeces have a Higher Heating Value (HHV) of 24 MJ/kg.

Faeces combustion was investigated using a bench-scale downdraft combustor test rig.

Combustion temperature of 431–558 °C was achieved at air flow rate of 10–18 L/min.

Fuel burn rate of 1.5–2.3 g/min was achieved at air flow rate of 10–18 L/min.

Combustion temperature of up to 600 ± 10 °C can handle 60 wt.% moisture in faeces.

Combustion temperature of up to 600 ± 10 °C can handle 60 wt.% moisture in faeces.

No MeSH data available.


(a and b): Combustion of simulant faeces (60 wt.% moisture): (a) at combustion temperature of 600 °C, air volumetric flow rate of 14 L/min, (b) at combustion temperature of 500 °C, air volumetric flow rate of 14 L/min, adjusted to 10 L/min after ∼1500 s.
