Paper presented at the 8th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Mauritius, 11-13 July, 2011.
This study presents results of gas fuels combustion - propane
and low calorific fuel. Low calorific fuel is produced during
e.g. biomass gasification, which has got of 13% H2, 4% CH4,
30% CO, 13% CO2, 40% N2. This composition is very similar
to composition of fuel obtained from wood pellets gasification.
Investigations have been performed at room temperature and at
conditions typical for High Temperature Air Combustion, i.e.
high temperature of the oxidizer (above the level of autoignition)
and low oxygen content (lower than 21 % as for
conventional combustion). Such environment has been created
on the base of exhaust gases coming from conventional gas
burner in small scale single fuel jet furnace. The temperature of
the exhaust gas as well as oxygen content has been adjusted in
order to achieve test conditions. Experimental results show
difficulties with burning of low calorific fuel at room
temperature and stable combustion at high temperature.
