Abstract
The invention discloses a method for realizing the intelligent temperature control of a combustor, comprising the following steps of: (1) arranging a regulating throttle on an air inlet of the combustor, thereby realizing multilevel wind-power control and effectively controlling flame intensity; (2) improving a backward impeller structure of the combustor, thereby shortening the height of the combustor and maintaining the original air volume and air pressure; (3) covering a fire-resistant tile structure of the combustor, thereby realizing a medium-speed flame mode; (4) strengthening the disturbance of outlet airflow of the combustor, thereby supplying proper air to the root of an atomizing torch in order to prevent oil gas from being pyrolyzed into carbon black for high-temperature oxygen shortage; (5) setting sharp levels by regulating the throttle, thereby controlling the proportion of fuel quantity and air quantity. Under the condition of sufficient combustion, combustion-supporting air which passes through the air inlet can realize the highest combustion temperature by using minimum limited quantity. The invention greatly improves the performance of air distribution quality and an air mixing system, and fuel is sufficiently combusted and has stable combustion effect.
