CONTROL FOR FUEL REFORMING REACTION BY WHICH METHANE IS PRODUCED

摘要

PROBLEM TO BE SOLVED: To provide a technique to achieve a high efficiency reforming reaction.

SOLUTION: The target value Tit of the temperature and the target value of the S/C (steam/carbon) of a gaseous starting material are set on the required load on a reformer 140 in ECU (control unit) 70. The temperature Ti of the gaseous starting material is controlled by a heating part 146 and the S/C is controlled by a pump 314. A desired temperature Tot of gas in the outlet side of a reforming part is set on the target value Tit of the temperature and the target value of the S/C of the gaseous starting material in ECU 70. The quantity of air is controlled by a pump 312 so that the temperature To of the gas becomes Tot. By this way, the fuel gas is produced in a quantity corresponding to the required load on the reformer by controlling the temperature and the S/C of the gaseous starting material properly. The reforming having high reforming efficiency is performed by controlling the quantity of air so that the gas temperature To becomes the desired gas temperature Tot.
