A model has been developed to describe asymmetric burning effects on the surface of particles in agglomerate. The model calculates the surface area of the particles that is available to burning from the geometric formation of the agglomerate. Average diameter of particles bonded in agglomerate is shown to have a burning time commensurate to the burning time of a single particle. Nevertheless, the burning time of agglomerate formed by the coalescing of liquid droplets, is shown to be greater than the burning time of a single particle.
