A Research on the Refuse Incinerators from the Viewpoint of Smoke Properties

抄録

The test results of the comprehensive investigations, which are carried out by the Department of Public Nuisance, the Tokyo Municipal Government, concerning the influence of the type and design principle of incinerators, operation conditions and refuse properties on the nuisances due to smoke and ash, give synthetic informations to improve the present policy of incinerator design, from the point of view of the public nuisance and also of incinerator maintenance. For instance, the upper limit of the furnace outlet temperature, which is supposed 950°C at present, is found slightly too high, considering the content of NO+NO₂ discharged from the furnace, and the maintenance of air preheater located immediately behind the furnace. Further, it is found difficult to decrease the content of organic acids even through high temperature incineration. In order to prevent the nuisances of these gases to the environment and the furnace itself, the present furnace volume design or other factors effective to decrease the content should be discussed.
