| Research Abstract |
Spray combustions of kerosene or thiophene (C_4H_4S) added kerosene were carried out using a rectangular furnace with a spray burner, and behavior of secondary condensed particle in the stack was investigated. In addition, it was also investigated when a water-cooled heat exchanger was placed in the stack assuming that a latent heat recovery was introduced. As a result, it was found that the number of particles increased along the stack from the upstream to the downstream. This result showed that secondary condensation particles formed in the stack. pH of condensed water formed in the heat exchanger was measured. When pure kerosene used as fuel, the pH was about 4.0. However it was from 2.3 to 2.5 in the case of thiophene added kerosene combustion and it was clear that sulfur in fuel lowered the pH of condensed water.
