Thermal Production and Combustion Gas Components of a Mixture of Waste Oil and Waste Liquid

摘要

The aim of the present study is to produce thermal energy from waste liquid. Emphasis is placed on the combustion gas analysis of free jets formed in stagnant air, in which a mixture of a waste liquid (e.g., pig-urine) and a waste oil is injected in the horizontal direction. Here the combustion gas components H_2, O_2, N_2, CH_4, CO, CO_2 and N_2O are measured with the aid of a gas chromatograph. Consideration is given to the effects of flow rates of waste oil, waste liquid and air on the concentration of N_2O. It is found that (ⅰ) the concentration of N_2O and its production are affected by the mix rate of waste oil and waste liquid, and (ⅱ) the corresponding production of N_2O is increased in the combustion gases of only waste oil.
