Burner system for solid oxide fuel cell involves reforming fuel, preheating air with non-stoichiometric combustor and recovering heat energy from fuel cell exhaust

摘要

Burner system comprises solid oxide monolithic fuel cell (15). Natural gas fuel is partially reformed before introduction into cell using a POX reformer (40) and air is preheated. Heat energy is recovered from the exhaust (46) of the fuel cell. 23-30% of fuel is supplied to the air preheater. The air preheater combustor and fuel burner are non-stoichiometric.
