| Summary: | A experiment was conducted in a laboratory scale controlled-air incinerator in to observe the effect of secondary combustion air temperature to secondary burner operation and its fuel consumption. Sawdust was partially burned in a primary combustion chamber while feeding with primary air at 30% of stoichiometric condition. An incomplete product of combustion flowed into the secondary combustion chamber to be re-burned with preheated secondary combustion air. It was discovered that increased secondary combustion air temperature affected the characteristics of the operation of the secondary burner and reduced its fuel consumption to a factor of 7.7 and 22.9% at a preheated secondary combustion air temperature of 500oC and 1000oC, respectively. |
