FIELD: starting a steam reformer in normal mode of operation.
SUBSTANCE: invention is related in particular to production of hydrogen, or methanol, or ammonia, or synthesis gas, and the burners connected to at least one reactor with reforming pipes are tuned and regulated. The start-up process takes place in successive start-up phases and is automatically controlled by the fact that the burners that ensure normal operation, in particular non-start-up burners, are ignited indirectly, depending on the temperature, by means of burners specially configured for starting, in particular pilot burners and starting burners, specifically depending on the automatically performed analysis of combustion control and/or temperature control, at least on the control burners. The burners that ensure normal operation are ignited indirectly, depending on the temperature, as a result of self-ignition, as at first the burners specially designed for starting are ignited indirectly by means of pilot burners, and the start is carried out and controlled automatically, as at first in the first start phase, the first group of burners is ignited as pilot burners, and then the next group of burners is ignited as starting burners, in particular by means of pilot burners, both of these first groups of burners are actuated in such a way that the temperature in the reactor rises above the autoignition temperature. After reaching the ignition temperature in the next start-up phase, the burners intended for normal operation in the next burner group are ignited and put into operation. The invention also relates to a control/adjustment device, a steam reformer and the use of a burner system.
EFFECT: reliable process optimization.
