1. A method for starting a steam reformer arrangement up to a normal operating state, the steam reformer arrangement comprising a reactor comprising reformer tubes and a plurality of burners, the plurality of burners comprising a first group of pilot burners, a second group of startup burners, and third group of non-startup burners, the steam reformer arrangement configured for production of hydrogen, methanol, ammonia, or synthesis gas, the method comprising:
controlling and regulating burners that are coupled to a reactor comprising reformer tubes, wherein startup is performed and regulated in an automated manner by the non-startup burners that ensure normal operation, wherein the non-startup burners are ignited indirectly as a function of temperature by the pilot burners and the startup burners provided specifically for startup, as a function of at least one of automatically evaluated flame monitoring or temperature monitoring at least with respect to the pilot burners.
