  • the present invention relates to a control system for an incinerating furnace and an incinerating furnace using the same.
  • the furnace To accomplish the complete combustion, that is no residue carbon in the exhaust gas, and toxic substances such as dioxin, PCB or the like are completely decomposed during the incineration, it is desirable to operate the furnace under the condition such that the temperature of the combustion chamber is kept more than 1,200 °C, the retention time of the combustion gas is more than 2 seconds, and the oxygen concentration in the combustion chamber is more than 3%.
  • the retention time of the combustion gas the more complete combustion is accomplished, however the capacity of the furnace may be reduced. For example, if a volume load is 100,000 Kcal/m 3 hr, and in case the 3% of an oxygen concentration and 1,200 °C of the exhaust gas, the retention time becomes approximately 4 seconds which is considered to be within a reasonable condition.
  • the volume load is more than 200,000 Kcal/m 3 hr by increasing the charging rate of the materials to be incinerated, the retention time of the exhaust gas becomes too short to accomplish the complete combustion, consequently the residue carbon in the exhaust gas increases or the dioxin is not completely decomposed by combustion heat, furthermore, it is threatening that they remain in the exhaust gas and are emitted into the air.
  • an amount of air for combustion equals to the amount of primary air which is heated to high temperature by the high temperature exhaust gas through the heat exchanger and is forced into the furnace from the furnace bottom.
