REACTOR COMBUSTION CONTROL METHOD AND REACTOR

摘要

A reactor combustion control method using a high temperature air combustion technology capable of reducing a temperature difference in a reactor without producing cracking and caulking in reaction tubes and the reactor controlled by using the method, the reactor wherein second burners ( 8 ) are disposed in a space formed between two or more reaction tubes ( 7 ) adjacent to each other so as to inject fuel in the extending direction of the reaction tubes ( 7 ), and partial combustion air feeding devices ( 10 ) and ( 11 ) for the second burners discharging exhaust gas in a combustion chamber ( 2 ) to the outside of the reactor through a permeable heat reservoir and feeding combustion air heated to a high temperature by the latent heat of the heat reservoir to the second burners ( 8 ) are installed; the method comprising the steps of raising the temperature in the reactor by the combustion of only the first burners ( 3 a) to ( 6 a) until the inside of a reactor body ( 1 ) is brought into a high temperature air combustion state, starting the combustion of the second burners ( 8 ) after the inside of the reactor body ( 1 ) is brought into the high temperature air combustion state, and decreasing the amount of combustion of the plurality of first burners ( 3 a) to ( 6 a) according an increase in combustion amount of the second burners ( 8 ) whereby a necessary combustion state can be provided.
