    In situ exposures were carried out in a waste fired, 75 MW, CFB boiler in Händelö, Sweden. The plant is burning 30–50% of household waste and 50–70% of industrial waste and deposit was found to be dominated by Na, K, Ca, Cl, S, and O. Low alloyed ferritic steel EN1.7380 [Fe-2.25Cr-1Mo] and the austenitic EN1.7380 [Fe-18Cr-9Ni] were exposed during 4 hours on air-cooled probes.

    6/5/2017 · Systematic measurements were conducted on a cold CFB with annular furnace and six parallel cyclones to study gas-solids flow in the annular furnace and flow non-uniformity among six cyclones. The results show that axial solids holdup in the annular furnace decreases exponentially with height, similar to the conventional rectangular furnace. The uniform transverse distribution of solids holdup
