摘要: Abstract Olivine is one of the refractory materials well-suited for fluidized-bed reactor technology. However, this material agglomerates at high temperatures due to presence sticky molten ash. The aim work investigate mechanism olivine agglomeration in reactors and determine risk factors agglomeration. A laboratory was designed study effect between ash bed material. systematic experiment performed ratio as a function different parameters (operating time, materials, content, temperature, gas flow additives). adhesion described, optimization prevent determined.
