Abstract
A method for regenerating a reformer to which fuel (12, 14) and an oxidant (16, 18, 20) are continuously fed, the feed rate of the fuel (12, 14) being reduced for the purpose of regeneration as compared to the feed rate in the continuous operation. According to the invention, the feed rate of the fuel (12, 14 is reduced during a plurality of successive regeneration intervals as compared to the feed rate in the continuous (normal) operation. The feed rate of the fuel (12, 14) between the successive intervals is higher than during them. A corresponding reformer has temperature sensors for implementing control of the fuel feed.

A method for regenerating a reformer fed with fuel and an oxidant in continuous operation, the feed rate of the fuel being reduced as compared to the feed rate in continuous operation for the purpose of regeneration, comprising the steps of:
- periodically reducing the feed rate of the fuel as compared to the feed rate of the fuel during continuous operation, and
- based on temperature conditions detected in the reformer during regeneration periods, temporarily increasing the feed rate of the fuel to above the reduced rate of the regeneration periods.
A reformer comprising:
- an oxidation zone and a reforming zone,
- means for supplying heat to the reforming zone,
- means for supplying a mixture of fuel and oxidant to the oxidation zone,
- means for supplying fuel to the reforming zone, and
- a controller for controlling operation and regeneration of the reformer,
- wherein the controller is adapted to feed the reformer with fuel and an oxidant during continuous operation,
- wherein the controller is adapted to periodically reduce the feed rate of the fuel as compared to the feed rate of the fuel during continuous operation for regeneration of the reformer, and
- wherein, during regeneration periods, the controller is adapted to temporarily increase the feed rate of the fuel to above that of the regeneration periods based on temperature conditions detected in the reformer.
