Abstract
Heat recovery from flue gas is very effective in order to economize fossil fuel consumption, and results in the reduction of CO_2 emission. However, the temperature of flue gas decreased with increasing the amount of recovery heat. It seems that the decrease of temperature causes formation of secondary condensed particles in a flue gas, and these particles is probably serious problem for air pollution and human health effect. In addition, the use of vegetable oil has an advantage as an alternative to fossil fuels for reduction of CO_2 emission. In this study, kerosene and kerosene with vegetable oil was burned using a spray combustion furnace and the flue gas was cooled by a heat exchanger. Flue gas was sampled from the stack, and PM size distribution and PM composition in the gas were analyzed. As the result, the mass of PM decreased by addition of vegetable oil. However, particles which were speculated as secondary condensed particles increased.
