A study was undertaken to provide information on which a more rational design of incinerators for human waste can be based. The laboratory techniques and method of data analysis may be adapted to provide similar information on sewage sludge solids or domestic refuse. The volatile matter and carbon remaining as a function of time was determined for different operating conditions of the volatilization chamber. The time rate of loss of material was found to be proportional to an exponential function of the fraction of material remaining. An equation is proposed to describe the volatilization process, and the dependence of the constants in the volatility equation on temperature and on the rate of air supply to the volatilization chamber was determined. Volatilization temperature as low as 300○C may be feasible for some incinerator designs that provide a reactor for the oxidation of the material volatilized.
