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 s o 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 (3a) to (6a) until the inside of a reactor body (1) is brought into a high temperatu re air combustion state, starting the combustion of the second burners (8) afte r 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 o f first burners (3a) to (6a) according an increase in combustion amount of the second burners (8), whereby a necessary combustion state can be provided.
