Method of controlling operation of fuel gas production apparatus

Abstract

An ECU detects various conditions of a home fuel gas refining system before starting operation of the home fuel gas refining system using pressure sensors and temperature sensors. Then, it is determined whether the detected conditions are abnormal or not. If abnormal conditions are determined, a self-repair process is performed for a predetermined abnormal condition among the conditions determined as abnormal.

1 . A method of controlling a fuel gas production apparatus for reforming a hydrogen-containing fuel into a reformed gas, and refining the reformed gas to produce a hydrogen-rich fuel gas, the method comprising the steps of: 
 detecting various conditions of said fuel gas production apparatus when a start up signal of said fuel gas production apparatus is inputted; and    performing a predetermined process for a predetermined condition among said detected conditions.    
   
   
       2 . A control method according to  claim 1 , wherein the various conditions of said fuel gas production apparatus are determined by measuring pressure and temperature.  
   
   
       3 . A control method according to  claim 1 , further comprising the steps of: 
 determining whether the detected conditions are abnormal; and    performing a self-repair process for a predetermined abnormal condition among conditions determined as abnormal.    
   
   
       4 . A control method according to  claim 3 , further comprising the step of displaying information about an abnormal condition which has been determined after the self-repair process.  
   
   
       5 . A control method according to  claim 1 , wherein the various conditions of said fuel gas production apparatus comprise an abnormal condition, and the method further comprises the steps of: 
 determining whether the detected abnormal condition should be handled by a process according to a stop pattern among a plurality of predetermined stop patterns; and    stopping operation of said fuel gas production apparatus according to the process of the determined stop pattern.    
   
   
       6 . A control method according to  claim 5 , further comprising the step of outputting a signal indicating the abnormal condition if the abnormal condition cannot be eliminated by self-repair.  
   
   
       7 . A control method according to  claim 5 , further, comprising the step of notifying the abnormal condition to a maintenance service company if the abnormal condition cannot be eliminated by self-repair.
