Abstract:
A combustion chamber comprising at least one combustion zone defined by at least one peripheral wall, at least one first fuel and air mixing duct for supplying fuel and air respectively into the at least one combustion zone, means to supply air into the at least one first fuel and air mixing duct, at least one catalytic partial oxidation reaction zone, at least one additional fuel and air mixing duct for supplying fuel and air respectively into the at least one catalytic partial oxidation reaction zone, means to supply fuel and air into the at least one additional fuel and air mixing duct, the at least one catalytic partial oxidation reaction zone being arranged to produce a product gas comprising a mixture of hydrogen, carbon monoxide, water, carbon dioxide and unreacted fuel, means to supply additional fuel into the product gas produced by the at least one catalytic partial oxidation reaction zone, means to mix the additional fuel and the product gas, and means to supply the product gas and additional fuel into the at least one first fuel and air mixing duct such that the product gas and additional fuel mix with the air in the first fuel and air mixing duct before being supplied into the at least one combustion zone.
