The experiments focus on analyzing the properties of the ash deposits, and determining how these properties are altered by a change in fuel type or boiler conditions. The properties of the ash determine whether it will corrode the boiler, hinder heat transfer, or pollute the environment. By performing experiments, we can determine the optimum boiler operating conditions and fuel types, so we can effectively utilize our knowledge of combustion processes to produce power.
Thermal Conductivity: a material property that gives the time rate of heat flow through a unit thickness of homogenous material
Emissivity: a material property that tells how much radiation a surface emits compared to an ideal black-body radiator
Mass and Volume Growth: the addition of matter to a particle by means of various processes
Sintering: the formation of a solid from a collection of particles, by "densifying" the material
Composition: the elements or chemicals that make up a material and their relative proportions
Corrosion: the chemical reaction between the metal surface and the ash deposits that produces a deterioration of the metal and its properties
NOx Formation: combustion of biomass and coal causes the production of NOx gases, which can be minimized with the proper fuel blend
