Pool Combustion of Iso-Propanol Fuel including IPA and PCBs in different Type Vessel

Abstract

On the regulation demanded for a control of various toxic substances, PCBs(poly chlorinated biphenyl) has a fatal poisonous matter in the ecosystem and the environmental pollution as it is a kind of stable chemical substance. Especially, the gross product of PCBs is estimated at about one million tonnage all over the world. However, it is kept on storing in untreated state, then has a deterioration by the prolonged storage and a risk of overflowing. Therefore, this research examined the fundamental characteristics of combustion and emission for the target of using the IPA (iso-propyl alcohol) solution as a part of PCBs control. IPA was filled to three kinds of Vessel, i.e., Vessel Ⅰ, Ⅱ, and Ⅲ, and then was investigated as follows; combustion shape, flame temperature, mass burning velocity, and PM(particulate matter). A radial thermometer and a C-A thermocouple measured the flame temperature, and the optical extinction method by using He-Ne laser and the filter weight method used in the PM measurement.As a result, with an increasing of L/S ratio, the flame length become shorter and the burning velocity is more rapid, but the particulate matters is higher. It is supposed that the air flow rate is high on Vessel?U, and then the combustion is promoted in the surface area of the upstream zone. The future works plan to investigate the characteristics with an using of the mixing of IPA and PCBs
