Afilaka, Daniel T. (2016) Avoiding the sintering of coal

2017-10-16 · absence and presence of coal (three types of bituminous coals) or coal ash. Results showed sintering and agglomerate formation of bed material can occur in the absence of coal or coal ash at a calcination temperature near 1200°C. Addition of coal or coal ash further promotes sintering and agglomerate formation at 1000°C.

Study on the Deposits Derived from a Biomass …

2012-6-14 · Biomass tends to form deposits and tends to slag during combustion. This study focused on deposits obtained from a circulating fluidized bed (CFB) in a biomass power plant. Analyses using scanning electron microscopy, energy-dispersive spectrometry, and X-ray diffraction are also included. The results indicate that the deposits are dense with a certain hardness, which resulted from the …

Circulating Fluidized Bed Combustion Technology …

Circulating Fluidized Bed Combustion Technology. Coal and peat ashes are usually trouble free at these temperatures, even if the melting point temperatures are in the same range with biomass fuels. Coal or peat is co-fired with biomass in many multi-fuel fired boilers. The woody biomass ashes are in general much more reactive than the
