摘要

A fuel cell power plant and a method of operating a fuel cell power plant which allows indirect control of the reformer burner flame temperature are disclosed. A hydrocarbon fuel (4) is reformed to provide a hydrogen rich fuel stream and the hydrogen rich fuel stream (8) is oxidized in a fuel cell (15). A stream of anode exhaust (16) and an oxidant stream comprising cathode exhaust (18) and air (26) are combusted in the reformer burner (20). The mass flow rate and composition of the oxidant stream are controlled to maintain the oxygen content of the burner exhaust (30) within a predetermined range and thus maintain the flame temperature of the combustion mixture within a preferred range.
