The Mathematical Model and Emperiences Algorithm of Activation Energy of Mixed Wastes

Abstract:

Through the single center of gravity mixture experiment design, the thermogravimetric combustion experiments of the cotton, easy chopsticks, food bags and its mixed components were done. Then the combustion characteristics curves of thermogravimetric and thermogravimetric differntial, and each group point average activation energy were obtained by above experiments. Using three Scheffe polynomial and the average activation energy of each waste component combustion, we get the activation energy calculation empirical formula of mixed waste combustion empirical formula. Through the three vertices of gravity method mixed waste combustion test, the experimental results of mixed waste activation energy fit well with the activation energy calculated from empirical formula. The activation energy calculated from empirical formula is correct, therefore, can be used to calculate the empirical formula derived from mixed waste activation energy. Application of this method has important guiding significance to the design of waste incinerator actually works and the waste combustion adjust.
