Within the reformer module, special fluid circuitry provides:
Splitting of anode offgas into staged combustion, giving an ascending temperature profile
Distribution and mixing of fuel into combustion air prior to each combustion stage
Efficient recovery of heat from flue gas and syngas for feed heating, steam raising and pre-reforming:
High grade heat used for high grade energy user - reforming
Pre-reforming converts C2+ in the feed to methane
Pre-reforming ensures low carbon activity above 600°C - reduced coking risk
Heat recovery sequence maintains desired temperature profile, even during turndown
