The Size Effect of Solid Waste Fuels on Their Combustion Characteristics in High Temperature Environment

Abstract

From the view point of effective use of solid waste fuels in the combustion furnaces, it is very important to examine the combustion characteristics of solid waste fuels in high temperature environment. Experiments have been carried out to elucidate the influence of initial diameter of solid waste fuels on their combustion properties such as ignition delay, total burning time and mass burning rate. The experimental conditions are 550℃ to 1100℃ of ambient temperature and 21% of oxygen concentration and the range of initial diameter of fuel sphere is 2.0mm to 5.0mm.
