Enhanced waste heat recovery using pre-reformers in combination with oxygen and fuel preheating for combustion

摘要

Supplying a non-pre-reformed hydrocarbon fuel gas stream to a pre-reformer to form a pre-reformed hydrocarbon fuel gas stream; Supplying the fuel gas to the fuel cell, burning the oxidant and the pre-reformed hydrocarbon fuel gas using the combustion device to generate the fuel gas, and heating the air by heat exchange with the fuel gas in the recuperator. And transferring the heat from the heated air to the pre-reformer tubes of the pre-reformer. A glass furnace system is also disclosed. [Selection diagram] Fig. 1
