Abstract
Recently a great deal of waste PET bottles has been accumulated in the stock yards without any management. In the other hand in the ceramic kiln furnace commercial grade LPG is generally employed as a gaseous fuel and used simply as a heat source. It is very useful and important to replace a part of gaseous propane with an alternative fuel such as PET-resin powder from the view point of energy saving and low environmental impact. In this paper based on physical and chemical properties of PET-resin powder, construction and dimensions of a ceramic burner suitable for twin fuel combustion are then designed to burn PET-resin powder as an auxiliary fuel, while gaseous propane is employed as a main fuel. By varying equivalence ratio under a constant combustion loading, combustion characteristics of the proposed ceramic burner are experimentally examined and analyzed by optical observation and measurements of temperature and composition.
